+# Nextcloud MCP Server Helm Chart
+
+This Helm chart deploys the Nextcloud MCP (Model Context Protocol) Server on a Kubernetes cluster, enabling AI assistants to interact with your Nextcloud instance.
+
+## Prerequisites
+
+- Kubernetes 1.19+
+- Helm 3.0+
+- A running Nextcloud instance (accessible from the Kubernetes cluster)
+- Nextcloud credentials (username/password for basic auth OR OAuth client for OAuth mode)
+
+## Installation
+
+### Quick Start with Basic Authentication
+
+```bash
+# Add the Helm repository
+helm repo add nextcloud-mcp https://cbcoutinho.github.io/nextcloud-mcp-server
+helm repo update
+
+# Install with basic auth (recommended for most users)
+helm install nextcloud-mcp nextcloud-mcp/nextcloud-mcp-server \
+  --set nextcloud.host=https://cloud.example.com \
+  --set auth.basic.username=myuser \
+  --set auth.basic.password=mypassword
+```
+
+### Using a values file
+
+Create a `custom-values.yaml` file:
+
+```yaml
+nextcloud:
+  host: https://cloud.example.com
+
+auth:
+  mode: basic
+  basic:
+    username: myuser
+    password: mypassword
+
+resources:
+  limits:
+    cpu: 1000m
+    memory: 512Mi
+  requests:
+    cpu: 100m
+    memory: 128Mi
+```
+
+Install with your custom values:
+
+```bash
+helm install nextcloud-mcp nextcloud-mcp/nextcloud-mcp-server -f custom-values.yaml
+```
+
+### OAuth Authentication Mode (Experimental)
+
+**Warning:** OAuth mode is experimental and requires patches to the Nextcloud `user_oidc` app. See the [Authentication Guide](https://github.com/cbcoutinho/nextcloud-mcp-server#authentication) for details.
+
+```yaml
+nextcloud:
+  host: https://cloud.example.com
+  mcpServerUrl: https://mcp.example.com
+  publicIssuerUrl: https://cloud.example.com
+
+auth:
+  mode: oauth
+  oauth:
+    # Optional: provide pre-registered client credentials
+    # If not provided, will use Dynamic Client Registration
+    clientId: "your-client-id"
+    clientSecret: "your-client-secret"
+    persistence:
+      enabled: true
+      size: 100Mi
+
+ingress:
+  enabled: true
+  className: nginx
+  hosts:
+    - host: mcp.example.com
+      paths:
+        - path: /
+          pathType: Prefix
+  tls:
+    - secretName: nextcloud-mcp-tls
+      hosts:
+        - mcp.example.com
+```
+
+## Configuration
+
+### Key Configuration Parameters
+
+#### Nextcloud Connection
+
+| Parameter | Description | Default |
+|-----------|-------------|---------|
+| `nextcloud.host` | URL of your Nextcloud instance (required) | `""` |
+| `nextcloud.mcpServerUrl` | MCP server URL for OAuth callbacks (OAuth only, optional) | Smart default* |
+| `nextcloud.publicIssuerUrl` | Public URL for browser-accessible OAuth authorization endpoint (OAuth only, optional) | Smart default** |
+
+**Smart Defaults:**
+- `*mcpServerUrl`: If not set, automatically uses ingress host (if enabled) or `http://localhost:8000` (for port-forward setups)
+- `**publicIssuerUrl`: If not set, defaults to `nextcloud.host`. **Only used for authorization endpoints** that browsers must access. All server-to-server endpoints (token, JWKS, introspection, userinfo) use URLs from OIDC discovery without rewriting
+
+#### Authentication
+
+| Parameter | Description | Default |
+|-----------|-------------|---------|
+| `auth.mode` | Authentication mode: `basic` or `oauth` | `basic` |
+| `auth.basic.username` | Nextcloud username (basic auth) | `""` |
+| `auth.basic.password` | Nextcloud password (basic auth) | `""` |
+| `auth.basic.existingSecret` | Use existing secret for credentials | `""` |
+| `auth.oauth.clientId` | OAuth client ID (OAuth mode, optional) | `""` |
+| `auth.oauth.clientSecret` | OAuth client secret (OAuth mode, optional) | `""` |
+| `auth.oauth.persistence.enabled` | Enable persistent storage for OAuth | `true` |
+| `auth.oauth.persistence.size` | Size of OAuth storage PVC | `100Mi` |
+
+#### Data Storage
+
+The `/app/data` directory is used for application data (token databases, Qdrant persistent storage, etc.). It is always mounted as writable to support the read-only root filesystem security context.
+
+| Parameter | Description | Default |
+|-----------|-------------|---------|
+| `dataStorage.enabled` | Enable persistent storage for `/app/data` | `false` |
+| `dataStorage.size` | Size of data storage PVC | `1Gi` |

+
+**When to enable persistence:**
+- Multi-user basic auth with offline access (stores `tokens.db`)
+- Qdrant persistent mode (stores vector database)
+- Any feature requiring persistent app data
+
+**When persistence is disabled:** Uses `emptyDir` (non-persistent, data lost on pod restart, but directory remains writable).
+

+
+## Examples
+
+### Example 1: Basic Auth with Ingress
+
+```yaml
+nextcloud:
+  host: https://cloud.example.com
+
+auth:
+  mode: basic
+  basic:
+    username: admin
+    password: secure-password
+
+ingress:
+  enabled: true
+  className: nginx
+  annotations:
+    cert-manager.io/cluster-issuer: letsencrypt-prod
+  hosts:
+    - host: mcp.example.com
+      paths:
+        - path: /
+          pathType: Prefix
+  tls:
+    - secretName: mcp-tls
+      hosts:
+        - mcp.example.com
+
+resources:
+  limits:
+    cpu: 2000m
+    memory: 1Gi
+  requests:
+    cpu: 200m
+    memory: 256Mi
+```
+
+### Example 2: Using Existing Secrets
+
+#### Basic Auth with Existing Secret
+
+Create a secret manually:
+
+```bash
+kubectl create secret generic nextcloud-credentials \
+  --from-literal=username=myuser \
+  --from-literal=password=mypassword
+```
+
+Then reference it in your values:
+
+```yaml
+nextcloud:
+  host: https://cloud.example.com
+
+auth:
+  mode: basic
+  basic:
+    existingSecret: nextcloud-credentials
+    usernameKey: username
+    passwordKey: password
+```
+
+#### OAuth with Existing Secret (Pre-registered Client)
+
+If you have a pre-registered OAuth client:
+
+```bash
+kubectl create secret generic nextcloud-oauth-creds \
+  --from-literal=clientId=my-oauth-client-id \
+  --from-literal=clientSecret=my-oauth-client-secret
+```
+
+Then reference it in your values:
+
+```yaml
+nextcloud:
+  host: https://cloud.example.com
+  # mcpServerUrl and publicIssuerUrl are optional!
+  # If not set, mcpServerUrl defaults to ingress host or localhost
+  # publicIssuerUrl defaults to nextcloud.host (only used for browser-accessible auth endpoint)
+
+auth:
+  mode: oauth
+  oauth:
+    existingSecret: nextcloud-oauth-creds
+    clientIdKey: clientId
+    clientSecretKey: clientSecret
+    persistence:
+      enabled: true
+
+ingress:
+  enabled: true
+  hosts:
+    - host: mcp.example.com
+      paths:
+        - path: /
+          pathType: Prefix
+  tls:
+    - secretName: mcp-tls
+      hosts:
+        - mcp.example.com
+```
+
+### Example 3: OAuth with Document Processing and Dynamic Client Registration
+
+This example shows OAuth without pre-registered credentials (using DCR) and optional URL values:
+
+```yaml
+nextcloud:
+  host: https://cloud.example.com
+  # mcpServerUrl will automatically use ingress host (https://mcp.example.com)
+  # publicIssuerUrl will automatically default to nextcloud.host (only used for browser-accessible auth endpoint)
+
+auth:
+  mode: oauth
+  oauth:
+    # No clientId/clientSecret - will use Dynamic Client Registration!
+    persistence:
+      enabled: true
+      storageClass: fast-ssd
+      size: 200Mi
+
+documentProcessing:
+  enabled: true
+  defaultProcessor: unstructured
+  unstructured:
+    enabled: true
+    apiUrl: http://unstructured-api:8000
+    strategy: hi_res
+    languages: eng,deu,fra
+
+ingress:
+  enabled: true
+  className: nginx
+  hosts:
+    - host: mcp.example.com
+      paths:
+        - path: /
+          pathType: Prefix
+```
+
+### Example 4: High Availability with Autoscaling
+
+```yaml
+replicaCount: 2
+
+autoscaling:

+### Example 5: Semantic Search with Qdrant and Ollama
+
+Deploy with vector search capabilities using embedded Qdrant and Ollama:
+
+```yaml
+nextcloud:
+  host: https://cloud.example.com
+
+auth:
+  mode: basic
+  basic:
+    username: admin
+    password: secure-password
+
+# Enable semantic search
+semanticSearch:
+  enabled: true
+  scanInterval: 1800  # Scan every 30 minutes
+  processorWorkers: 5
+
+# Deploy Qdrant as a subchart
+qdrant:
+  enabled: true
+  persistence:
+    size: 20Gi
+    storageClass: fast-ssd
+  resources:
+    requests:
+      cpu: 500m
+      memory: 1Gi
+    limits:
+      cpu: 2000m
+      memory: 4Gi
+
+# Deploy Ollama as a subchart
+ollama:
+  enabled: true
+  embeddingModel: nomic-embed-text
+  persistentVolume:
+    size: 30Gi
+    storageClass: standard
+  resources:
+    requests:
+      cpu: 1000m
+      memory: 2Gi
+    limits:
+      cpu: 4000m
+      memory: 8Gi
+```
+
+Or use an external Ollama instance:
+
+```yaml
+semanticSearch:
+  enabled: true
+
+qdrant:
+  enabled: true
+
+# Use external Ollama instead of deploying subchart
+ollama:
+  enabled: false
+  url: "http://ollama.ai-services.svc.cluster.local:11434"
+  embeddingModel: nomic-embed-text
+```
+
+Or use OpenAI for embeddings:
+
+```yaml
+semanticSearch:
+  enabled: true
+
+qdrant:
+  enabled: true
+
+# Use OpenAI instead of Ollama
+openai:
+  enabled: true
+  apiKey: "sk-..."
+  # Or use existing secret:
+  # existingSecret: openai-api-key
+  # secretKey: api-key
+```
+
+## Upgrading
+
+### To upgrade an existing deployment:
+
+```bash
+# Update the repository
+helm repo update
+
+# Upgrade with your custom values
+helm upgrade nextcloud-mcp nextcloud-mcp/nextcloud-mcp-server -f custom-values.yaml
+```
+
+### To upgrade with new values:
+
+```bash
+helm upgrade nextcloud-mcp nextcloud-mcp/nextcloud-mcp-server \
+  --set resources.limits.memory=1Gi
+```
+
+## Uninstalling
+
+```bash
+helm uninstall nextcloud-mcp
+```
+
+**Note:** This will delete all resources including PVCs. If you want to preserve OAuth client data, backup the PVC before uninstalling.
+
+## Troubleshooting
+
+### Check pod status
+
+```bash
+kubectl get pods -l app.kubernetes.io/name=nextcloud-mcp-server
+```
+
+### View logs
+
+```bash
+kubectl logs -l app.kubernetes.io/name=nextcloud-mcp-server --tail=100 -f
+```
+
+### Check health endpoints
+
+The application exposes health check endpoints for monitoring:
+
+```bash
+# Port forward to the service
+kubectl port-forward svc/nextcloud-mcp 8000:8000
+
+# Check liveness (if app is running)
+curl http://localhost:8000/health/live
+
+# Check readiness (if app is ready to serve traffic)
+curl http://localhost:8000/health/ready
+```
+
+**Example responses:**
+
+Liveness (always returns 200 if running):
+```json
+{
+  "status": "alive",
+  "mode": "basic"
+}
+```
+
+Readiness (returns 200 if ready, 503 if not ready):
+```json
+{
+  "status": "ready",
+  "checks": {
+    "nextcloud_configured": "ok",
+    "auth_mode": "basic",
+    "auth_configured": "ok"
+  }
+}
+```
+
+### Common Issues
+
+1. **Connection refused to Nextcloud**
+   - Verify `nextcloud.host` is accessible from the Kubernetes cluster
+   - For OAuth mode: Ensure MCP server can reach OIDC discovery endpoints (token, JWKS, introspection, userinfo URLs)
+   - Check network policies and firewall rules
+   - Note: Do not use internal Docker hostnames (like `http://app:80`) for `nextcloud.host` - use externally resolvable URLs
+
+2. **Authentication failures**
+   - For basic auth: verify username/password are correct
+   - For OAuth: check that OIDC app is properly configured
+
+3. **OAuth persistence issues**
+   - Verify PVC is bound: `kubectl get pvc`
+   - Check storage class exists: `kubectl get storageclass`
+
+4. **Resource constraints**
+   - Increase memory limits if seeing OOM errors
+   - Adjust CPU requests based on load
+
+## Security Considerations
+
+1. **Secrets Management**: Consider using external secret management (e.g., Sealed Secrets, External Secrets Operator)
+2. **TLS**: Always use TLS/HTTPS for production deployments
+3. **Network Policies**: Restrict network access to necessary services only
+4. **RBAC**: Review and customize ServiceAccount permissions as needed
+5. **App Passwords**: For basic auth, use Nextcloud app passwords instead of main account passwords
