+
+## Version Management
+
+This monorepo uses commitizen for version management with **independent versioning** for three components:
+
+### Components
+
+| Component | Scope | Bump Command | Tag Example |
+|-----------|-------|--------------|-------------|
+| MCP Server | `mcp` or none | `./scripts/bump-mcp.sh` | `v0.54.0` |
+| Helm Chart | `helm` | `./scripts/bump-helm.sh` | `nextcloud-mcp-server-0.54.0` |
+| Astrolabe App | `astrolabe` | `./scripts/bump-astrolabe.sh` | `astrolabe-v0.2.0` |
+
+### Commit Message Format
+
+Use conventional commits with **scopes** to target specific components:
+
+```bash
+# MCP server changes
+feat(mcp): add calendar sync API
+fix(mcp): resolve authentication bug
+
+# Helm chart changes
+feat(helm): add resource limits
+docs(helm): update values documentation
+
+# Astrolabe app changes
+feat(astrolabe): add dark mode toggle
+fix(astrolabe): resolve search UI bug
+```
+
+**Unscoped commits** default to the MCP server:
+```bash
+feat: add new feature  # → MCP server (v0.54.0)
+```
+
+### Release Workflow
+
+#### 1. Make Changes with Scoped Commits
+
+```bash
+git commit -m "feat(astrolabe): add dark mode toggle"
+git commit -m "feat(helm): add ingress annotations"
+git commit -m "feat(mcp): add calendar sync"
+```
+
+#### 2. Bump Component Versions
+
+```bash
+# Bump MCP server (reads commits with scope=mcp or unscoped)
+./scripts/bump-mcp.sh
+# → Creates tag: v0.54.0
+# → Updates: pyproject.toml, Chart.yaml:appVersion
+
+# Bump Helm chart (reads commits with scope=helm)
+./scripts/bump-helm.sh
+# → Creates tag: nextcloud-mcp-server-0.54.0
+# → Updates: Chart.yaml:version
+
+# Bump Astrolabe (reads commits with scope=astrolabe)
+./scripts/bump-astrolabe.sh
+# → Creates tag: astrolabe-v0.2.0
+# → Updates: info.xml, package.json
+```
+
+#### 3. Push Tags
+
+```bash
+git push --follow-tags
+```
+
+### Changelog Filtering
+
+Each component maintains its own `CHANGELOG.md`:
+
+- **MCP Server**: `CHANGELOG.md` (root) - includes `feat(mcp):` and unscoped commits
+- **Helm Chart**: `charts/nextcloud-mcp-server/CHANGELOG.md` - includes `feat(helm):` only
+- **Astrolabe**: `third_party/astrolabe/CHANGELOG.md` - includes `feat(astrolabe):` only
+
+### Manual Version Bumps
+
+For specific increments:
+
+```bash
+# Patch bump (0.53.0 → 0.53.1)
+uv run cz bump --increment PATCH
+
+# Minor bump (0.53.0 → 0.54.0)
+uv run cz bump --increment MINOR
+
+# Major bump (0.53.0 → 1.0.0)
+uv run cz bump --increment MAJOR
+
+# For non-MCP components, use --config
+cd charts/nextcloud-mcp-server
+uv run cz --config .cz.toml bump --increment MINOR
+```
+
+### Versioning Philosophy
+
+- **MCP Server**: Follows PEP 440, `major_version_zero = true` (0.x.x for pre-1.0)
+- **Helm Chart**: Follows PEP 440, starts at 0.53.0 (continues from current)
+- **Astrolabe**: Follows PEP 440, `major_version_zero = true` (0.x.x for alpha/beta)
+
+### Chart.yaml Version vs appVersion
+
+The Helm chart has TWO version fields:
+
+- **`version`**: Chart packaging version (bumped by `feat(helm):`)
+  - Example: `0.53.0` → `0.54.0` when adding resource limits
+
+- **`appVersion`**: MCP server version being deployed (bumped by `feat(mcp):`)
+  - Example: `"0.53.0"` → `"0.54.0"` when MCP server releases
+
+This allows the chart to evolve independently from the application.

+Database Migrations for nextcloud-mcp-server
+============================================
+
+This directory contains Alembic database migrations for the token storage database.
+
+Structure
+---------
+- env.py: Alembic environment configuration
+- script.py.mako: Template for generating new migration files
+- versions/: Directory containing migration scripts
+
+Usage
+-----
+Migrations are managed via the CLI:
+
+    # Upgrade database to latest version
+    uv run nextcloud-mcp-server db upgrade
+
+    # Show current database version
+    uv run nextcloud-mcp-server db current
+
+    # Show migration history
+    uv run nextcloud-mcp-server db history
+
+    # Create a new migration (developers only)
+    uv run nextcloud-mcp-server db migrate "description of changes"
+
+    # Downgrade database by one version (emergency use only)
+    uv run nextcloud-mcp-server db downgrade
+
+Direct Alembic Usage
+--------------------
+You can also use Alembic commands directly:
+
+    # Specify database URL via -x flag
+    uv run alembic -x database_url=sqlite+aiosqlite:////path/to/tokens.db upgrade head
+
+    # Or set in alembic.ini and run
+    uv run alembic upgrade head
+    uv run alembic current
+    uv run alembic history
+
+Writing Migrations
+------------------
+Since we don't use SQLAlchemy models, migrations are written with raw SQL:
+
+    def upgrade() -> None:
+        op.execute("""
+            ALTER TABLE refresh_tokens
+            ADD COLUMN new_field TEXT
+        """)
+
+    def downgrade() -> None:
+        # SQLite doesn't support DROP COLUMN, use table recreation
+        op.execute("""
+            CREATE TABLE refresh_tokens_new AS
+            SELECT user_id, encrypted_token, ... FROM refresh_tokens
+        """)
+        op.execute("DROP TABLE refresh_tokens")
+        op.execute("ALTER TABLE refresh_tokens_new RENAME TO refresh_tokens")
+
+Migration File Naming
+---------------------
+Format: YYYYMMDD_HHMM_<revision>_<slug>.py
+Example: 20251217_2200_001_initial_schema.py
+
+Notes
+-----
+- Migrations run automatically when RefreshTokenStorage.initialize() is called
+- Existing databases are automatically stamped with the initial version
+- SQLite has limited ALTER TABLE support - complex changes require table recreation

+# Database Migrations
+
+This document describes the database migration system for nextcloud-mcp-server's token storage database.
+
+## Overview
+
+The token storage database uses [Alembic](https://alembic.sqlalchemy.org/) for schema versioning and migrations. Alembic provides:
+
+- **Version Control**: Track schema changes in Git
+- **Rollback Support**: Safely downgrade schema if needed
+- **Audit Trail**: Migration files serve as schema changelog
+- **Automated Upgrades**: Database schema updates automatically on startup
+
+## Architecture
+
+### Migration Strategy
+
+The system handles three scenarios:
+
+1. **New Database**: Runs migrations from scratch to create all tables
+2. **Pre-Alembic Database**: Stamps existing database with initial revision (no changes)
+3. **Alembic-Managed Database**: Upgrades to latest version automatically
+
+### Directory Structure
+

+    └── migrations.py                     # Migration utilities
+```
+
+## Usage
+
+### Automatic Migration on Startup
+
+Migrations run automatically when the server starts:
+
+```bash
+uv run nextcloud-mcp-server
+```
+
+The `RefreshTokenStorage.initialize()` method:
+1. Checks if database is Alembic-managed
+2. Stamps pre-Alembic databases with initial revision
+3. Upgrades to latest version
+
+### Manual Migration Commands
+
+```bash
+# Show current database version
+uv run nextcloud-mcp-server db current
+
+# Upgrade database to latest version
+uv run nextcloud-mcp-server db upgrade
+
+# Show migration history
+uv run nextcloud-mcp-server db history
+
+# Downgrade by one version (emergency use only)
+uv run nextcloud-mcp-server db downgrade
+
+# Specify custom database path
+uv run nextcloud-mcp-server db current -d /path/to/tokens.db
+```
+
+### Environment Variables
+
+- `TOKEN_STORAGE_DB`: Path to database file (default: `/app/data/tokens.db`)
+
+## Creating Migrations (Developers)
+
+### Step 1: Create Migration File
+
+```bash
+uv run nextcloud-mcp-server db migrate "add user preferences table"
+```
+
+This creates a new migration file in `alembic/versions/` with empty `upgrade()` and `downgrade()` functions.
+
+### Step 2: Write Migration SQL
+
+Since we don't use SQLAlchemy models, write raw SQL:
+
+```python
+def upgrade() -> None:
+    """Add user preferences table."""
+    op.execute("""
+        CREATE TABLE user_preferences (
+            user_id TEXT PRIMARY KEY,
+            theme TEXT DEFAULT 'light',
+            language TEXT DEFAULT 'en',
+            created_at INTEGER NOT NULL
+        )
+    """)
+
+    op.execute("""
+        CREATE INDEX idx_user_preferences_user_id
+        ON user_preferences(user_id)
+    """)
+
+
+def downgrade() -> None:
+    """Remove user preferences table."""
+    op.execute("DROP INDEX IF EXISTS idx_user_preferences_user_id")
+    op.execute("DROP TABLE IF EXISTS user_preferences")
+```
+
+### Step 3: Test Migration
+
+```bash
+# Test upgrade
+uv run nextcloud-mcp-server db upgrade -d /tmp/test.db
+
+# Verify schema
+sqlite3 /tmp/test.db ".schema"
+
+# Test downgrade
+uv run nextcloud-mcp-server db downgrade -d /tmp/test.db
+
+# Verify removal
+sqlite3 /tmp/test.db ".schema"
+```
+
+### Step 4: Commit Migration
+
+```bash
+git add alembic/versions/YYYYMMDD_HHMM_XXX_description.py
+git commit -m "feat: add user preferences table migration"
+```
+
+## SQLite Limitations
+
+SQLite has limited `ALTER TABLE` support:
+
+### Supported Operations
+
+- ✅ Add columns: `ALTER TABLE table ADD COLUMN ...`
+- ✅ Rename table: `ALTER TABLE old RENAME TO new`
+- ✅ Rename column: `ALTER TABLE table RENAME COLUMN old TO new` (SQLite 3.25+)
+
+### Unsupported Operations (Requires Table Recreation)
+
+- ❌ Drop column
+- ❌ Change column type
+- ❌ Add constraints to existing columns
+
+### Table Recreation Pattern
+
+For complex schema changes:
+
+```python
+def upgrade() -> None:
+    # Create new table with desired schema
+    op.execute("""
+        CREATE TABLE refresh_tokens_new (
+            user_id TEXT PRIMARY KEY,
+            encrypted_token BLOB NOT NULL,
+            new_field TEXT,  -- New column
+            expires_at INTEGER,
+            created_at INTEGER NOT NULL
+        )
+    """)
+
+    # Copy data from old table
+    op.execute("""
+        INSERT INTO refresh_tokens_new
+        (user_id, encrypted_token, expires_at, created_at)
+        SELECT user_id, encrypted_token, expires_at, created_at
+        FROM refresh_tokens
+    """)
+
+    # Drop old table and rename new table
+    op.execute("DROP TABLE refresh_tokens")
+    op.execute("ALTER TABLE refresh_tokens_new RENAME TO refresh_tokens")
+
+    # Recreate indexes
+    op.execute("CREATE INDEX idx_user_id ON refresh_tokens(user_id)")
+```
+
+## Best Practices
+
+### Naming Conventions
+
+- **Migrations**: `YYYYMMDD_HHMM_XXX_description.py`
+- **Revision IDs**: Sequential numbers (`001`, `002`, `003`)
+- **Descriptions**: Imperative mood ("add table", "remove column")
+
+### Migration Guidelines
+
+1. **Test Thoroughly**: Test both upgrade and downgrade paths
+2. **Preserve Data**: Ensure data migration logic is correct
+3. **Document Changes**: Add comments explaining complex operations
+4. **Small Changes**: One logical change per migration
+5. **No Breaking Changes**: Maintain backward compatibility when possible
+
+### Downgrade Considerations
+
+- **Data Loss**: Downgrade may lose data (dropped columns, tables)
+- **Confirmation**: Downgrade command requires explicit confirmation
+- **Testing**: Always test downgrade path before deploying
+- **Emergency Only**: Use downgrades only for critical rollbacks
+
+## Backward Compatibility
+
+### Pre-Alembic Databases
+
+Existing databases created before Alembic integration are automatically detected and stamped with revision `001`:
+
+1. Server detects no `alembic_version` table
+2. Checks if `refresh_tokens` table exists
+3. If yes, stamps database with `001` (no schema changes)
+4. Future updates use normal migration path
+
+### Migration Path
+
+```
+Pre-Alembic DB → Stamp(001) → Upgrade(002) → Upgrade(003) → ...
+New DB → Migrate(001) → Upgrade(002) → Upgrade(003) → ...
+```
+
+## Troubleshooting
+
+### Migration Fails
+
+```bash
+# Check current state
+uv run nextcloud-mcp-server db current -d /path/to/tokens.db
+
+# View migration history
+uv run nextcloud-mcp-server db history -d /path/to/tokens.db
+
+# Manually inspect database
+sqlite3 /path/to/tokens.db ".schema"
+```
+
+### Reset to Initial State
+
+**WARNING: This destroys all data!**
+
+```bash
+# Downgrade to base (empty database)
+uv run nextcloud-mcp-server db downgrade -d /path/to/tokens.db --revision base
+
+# Upgrade to latest
+uv run nextcloud-mcp-server db upgrade -d /path/to/tokens.db
+```
+
+### Corrupted Migration State
+
+If `alembic_version` table is corrupted:
+
+```bash
+# Manually fix via SQL
+sqlite3 /path/to/tokens.db
+> DELETE FROM alembic_version;
+> INSERT INTO alembic_version (version_num) VALUES ('001');
+> .quit
+
+# Verify and upgrade
+uv run nextcloud-mcp-server db current -d /path/to/tokens.db
+uv run nextcloud-mcp-server db upgrade -d /path/to/tokens.db
+```
+
+## CI/CD Integration
+
+### Pre-Deployment
+
+```bash
+# Run migrations in test environment
+export TOKEN_STORAGE_DB=/app/data/tokens.db
+uv run nextcloud-mcp-server db upgrade
+
+# Verify current version
+uv run nextcloud-mcp-server db current
+```
+
+### Docker Deployment
+
+Migrations run automatically on container startup via `RefreshTokenStorage.initialize()`.
+
+### Rollback Plan
+
+1. Stop application
+2. Backup database: `cp tokens.db tokens.db.backup`
+3. Downgrade: `uv run nextcloud-mcp-server db downgrade --revision XXX`
+4. Deploy previous application version
+5. Restart application

 ```
 
+### CLI Subcommands
+
+The `nextcloud-mcp-server` CLI has two main subcommands:
+
+1. **`run`** - Start the MCP server (default command in Docker)
+   ```bash
+   uv run nextcloud-mcp-server run --oauth --host 0.0.0.0 --port 8000
+   ```
+
+2. **`db`** - Database migration management (Alembic)
+   ```bash
+   # Show current migration revision
+   uv run nextcloud-mcp-server db current
+
+   # Upgrade to latest migration
+   uv run nextcloud-mcp-server db upgrade
+
+   # Show migration history
+   uv run nextcloud-mcp-server db history
+
+   # Create new migration (developers only)
+   uv run nextcloud-mcp-server db migrate "description of changes"
+   ```
+
+### Database Migrations
+
+Token storage uses **Alembic** for schema management:
+
+- **Automatic migrations**: Database is upgraded automatically on server startup
+- **Backward compatibility**: Pre-Alembic databases are automatically stamped with the initial revision
+- **Migration files**: Located in `alembic/versions/`
+- **For developers**: When changing the schema:
+  1. Create a migration: `uv run nextcloud-mcp-server db migrate "add new column"`
+  2. Edit the generated file in `alembic/versions/` to add SQL statements
+  3. Test upgrade: `uv run nextcloud-mcp-server db upgrade`
+  4. Test downgrade: `uv run nextcloud-mcp-server db downgrade`
+
+See [Database Migrations Guide](database-migrations.md) for detailed information.

+## astrolabe-v0.2.0 (2025-12-19)
+
+### BREAKING CHANGE
+
+- Search algorithms now require Qdrant to be populated.
+Vector sync must be enabled and documents indexed for search to work.
+- All OAuth deployments must be reconfigured to specify
+resource URIs (NEXTCLOUD_MCP_SERVER_URL and NEXTCLOUD_RESOURCE_URI) and
+choose between multi-audience or token exchange mode.
+- FASTMCP_-prefixed env vars have been replaced by CLI
+arguments. Refer to the README for updated usage.

+                    GNU AFFERO GENERAL PUBLIC LICENSE
+                       Version 3, 19 November 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU Affero General Public License is a free, copyleft license for
+software and other kinds of works, specifically designed to ensure
+cooperation with the community in the case of network server software.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+our General Public Licenses are intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  Developers that use our General Public Licenses protect your rights
+with two steps: (1) assert copyright on the software, and (2) offer
+you this License which gives you legal permission to copy, distribute
+and/or modify the software.
+
+  A secondary benefit of defending all users' freedom is that
+improvements made in alternate versions of the program, if they
+receive widespread use, become available for other developers to
+incorporate.  Many developers of free software are heartened and
+encouraged by the resulting cooperation.  However, in the case of
+software used on network servers, this result may fail to come about.
+The GNU General Public License permits making a modified version and
+letting the public access it on a server without ever releasing its
+source code to the public.
+
+  The GNU Affero General Public License is designed specifically to
+ensure that, in such cases, the modified source code becomes available
+to the community.  It requires the operator of a network server to
+provide the source code of the modified version running there to the
+users of that server.  Therefore, public use of a modified version, on
+a publicly accessible server, gives the public access to the source
+code of the modified version.
+
+  An older license, called the Affero General Public License and
+published by Affero, was designed to accomplish similar goals.  This is
+a different license, not a version of the Affero GPL, but Affero has
+released a new version of the Affero GPL which permits relicensing under
+this license.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU Affero General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Remote Network Interaction; Use with the GNU General Public License.
+
+  Notwithstanding any other provision of this License, if you modify the
+Program, your modified version must prominently offer all users
+interacting with it remotely through a computer network (if your version
+supports such interaction) an opportunity to receive the Corresponding
+Source of your version by providing access to the Corresponding Source
+from a network server at no charge, through some standard or customary
+means of facilitating copying of software.  This Corresponding Source
+shall include the Corresponding Source for any work covered by version 3
+of the GNU General Public License that is incorporated pursuant to the
+following paragraph.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the work with which it is combined will remain governed by version
+3 of the GNU General Public License.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU Affero General Public License from time to time.  Such new versions
+will be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU Affero General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU Affero General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU Affero General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU Affero General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU Affero General Public License for more details.
+
+    You should have received a copy of the GNU Affero General Public License
+    along with this program.  If not, see <https://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If your software can interact with users remotely through a computer
+network, you should also make sure that it provides a way for users to
+get its source.  For example, if your program is a web application, its
+interface could display a "Source" link that leads users to an archive
+of the code.  There are many ways you could offer source, and different
+solutions will be better for different programs; see section 13 for the
+specific requirements.
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU AGPL, see
+<https://www.gnu.org/licenses/>.

+# Astrolabe: The Intelligence Layer for Nextcloud
+
+Your Nextcloud instance is more than just a bucket for files—it is a galaxy of ideas, projects, and knowledge. But until now, you've been navigating it in the dark, relying on exact filenames and rigid keywords.
+
+**It's time to turn the lights on.**
+
+Astrolabe is a fully integrated Nextcloud application that transforms your server into a semantic intelligence engine. It doesn't just store your data; it **maps it, understands it, and connects it** to the AI future.
+
+---
+
+## What You Can Do
+
+### 🔍 Search That Actually Understands
+
+Forget clunky external tools. Astrolabe registers as a **native Nextcloud Search Provider**.
+
+- **Seamless**: Lives right in the standard Nextcloud search bar you already use
+- **Semantic**: Type "marketing strategy for the winter launch" and Astrolabe finds the relevant PDFs, chat logs, and text files—even if those exact words never appear in the document
+- **Intelligent**: It finds the **concept**, not just the string
+
+### 🌌 Visualize Your Data Universe
+
+Data shouldn't just be a list; it should be a landscape. Astrolabe includes a dedicated dashboard that visualizes your document chunks as a **3D PCA Vector Plot**.
+
+- **See the Connections**: View your data as a constellation of points in 3D space
+- **Explore Clusters**: Visually identify how your documents relate to one another
+- **True "Astroglobe" Experience**: Rotate, zoom, and fly through your semantic universe just like navigators once studied the stars
+
+### 🤖 Power Your AI Agents
+
+Astrolabe isn't just for humans; it's for your AI agents, too. It acts as a bridge, running a **Model Context Protocol (MCP) Server** directly from your Nextcloud.
+
+- **Bring Your Own Brain**: Connect external AI clients (like Claude Desktop or Cursor) to your private data
+- **Agentic Workflows**: Enable LLMs to "sample" your files, read content, and perform complex reasoning tasks using your Nextcloud data as the source of truth
+- **Private & Secure**: Your data never leaves your infrastructure
+
+---
+
+## Installation
+
+### From App Store (Recommended)
+
+1. Open **Apps** in your Nextcloud
+2. Search for **"Astrolabe"**
+3. Click **"Download and enable"**
+
+### Manual Installation
+
+```bash
+# Clone into your Nextcloud apps directory
+cd /path/to/nextcloud/apps
+git clone https://github.com/cbcoutinho/nextcloud-mcp-server.git
+cd nextcloud-mcp-server/third_party/astrolabe
+
+# Install dependencies
+composer install
+
+# Enable the app
+php /path/to/nextcloud/occ app:enable astrolabe
+```
+
+---
+
+## Quick Start
+
+### 1. Configure the MCP Server URL
+
+Add this to your Nextcloud `config/config.php`:
+
+```php
+'mcp_server_url' => 'http://localhost:8000',
+```
+
+### 2. Start the MCP Server
+
+The MCP server handles semantic search and AI agent connections. See the [MCP Server Installation Guide](https://github.com/cbcoutinho/nextcloud-mcp-server/blob/master/docs/installation.md) for details.
+
+Quick start with Docker:
+
+```bash
+docker run -p 127.0.0.1:8000:8000 --env-file .env --rm \
+  ghcr.io/cbcoutinho/nextcloud-mcp-server:latest --oauth
+```
+
+### 3. Authorize Access
+
+1. Go to **Settings → Personal → Astrolabe**
+2. Click **"Authorize Access"**
+3. Sign in to your identity provider
+4. Approve the requested permissions
+
+That's it! You can now use semantic search and explore your data universe.
+
+---
+
+## Features
+

+
+- **Server Status**: Monitor MCP server health and version
+- **Vector Sync Metrics**: See how many documents are indexed, processing rates, and sync status
+- **Configuration Validation**: Verify server URL and connectivity
+- **Feature Availability**: Check which capabilities are enabled
+
+### Unified Search Integration
+
+Astrolabe integrates directly with Nextcloud's **Unified Search**:
+
+- Available in the top search bar across all Nextcloud pages
+- Returns semantic matches ranked by relevance
+- Shows excerpts from matching documents
+- Links directly to source files in Nextcloud
+
+---
+
+## Use Cases
+
+### For Individuals
+
+- **Research**: Find all notes related to a project, even if they use different terminology
+- **Organization**: Discover forgotten documents related to your current work
+- **Exploration**: Visualize how your knowledge connects and evolves over time
+
+### For Teams
+
+- **Knowledge Discovery**: Surface institutional knowledge that would otherwise stay buried
+- **Collaboration**: Find team members working on similar problems
+- **Documentation**: Locate relevant documentation without knowing exact titles
+
+### For Developers
+
+- **AI Integration**: Connect Claude Desktop, Cursor, or other MCP clients to Nextcloud
+- **RAG Workflows**: Build retrieval-augmented generation pipelines on your private data
+- **Custom Agents**: Use the MCP protocol to create specialized workflows
+
+---
+
+## Requirements
+
+- **Nextcloud**: Version 30 or later
+- **MCP Server**: Running instance (Docker recommended)
+- **Identity Provider**: OAuth provider supporting PKCE (Nextcloud OIDC Login or Keycloak)
+- **Vector Sync**: Optional but recommended for semantic search (see [configuration guide](https://github.com/cbcoutinho/nextcloud-mcp-server/blob/master/docs/configuration.md))

+
+### Troubleshooting
+
+**Cannot connect to MCP server:**
+- Verify `mcp_server_url` in `config.php`
+- Check MCP server is running: `curl http://localhost:8000/health`
+- Review logs: `tail -f data/nextcloud.log`
+
+**Authorization fails:**
+- Ensure MCP server is in OAuth mode
+- Verify identity provider is accessible
+- Check browser console for errors
+
+**Semantic search returns no results:**
+- Verify vector sync is enabled and running
+- Check indexing status in Admin settings
+- Allow time for initial indexing to complete

+# Astrolabe - Semantic Search for Nextcloud
+
+Find your content by meaning, not just keywords. Astrolabe brings AI-powered semantic search to your Nextcloud, helping you discover documents, notes, calendar events, and files through natural language.
+
+## Features
+
+- **Semantic Search**: Search across Notes, Files, Calendar, Deck, and more using natural language queries
+- **Unified Search Integration**: Results appear in Nextcloud's global search bar alongside traditional results
+- **Background Indexing**: Your content is automatically indexed for instant semantic search
+- **Vector Visualization**: Explore your content in an interactive 2D visualization showing semantic relationships
+- **Hybrid Search**: Combines semantic understanding with keyword matching for best results
+
+## How It Works
+
+Astrolabe connects to a semantic search service that understands the meaning of your content. Instead of exact keyword matches, you can search for concepts - ask "meeting notes from last week" or "recipes with chicken" and find relevant documents even if they don't contain those exact words.
+
+## Getting Started
+
+1. Install and enable the app
+2. Grant background access to allow indexing of your content
+3. Start searching with natural language in Nextcloud's search bar
+
+See [documentation](https://github.com/cbcoutinho/nextcloud-mcp-server) for configuration details.
