From 286a3eb20f7b1c27498b5cde3ea4da83699b44dd Mon Sep 17 00:00:00 2001 From: Chris Coutinho Date: Sat, 20 Dec 2025 20:55:31 +0100 Subject: [PATCH] feat(auth): add multi-user BasicAuth pass-through mode MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implement multi-user BasicAuth pass-through mode (ADR-020) where each request includes BasicAuth credentials that are forwarded to Nextcloud APIs without persistent storage. Changes: - Add _get_client_from_basic_auth() in context.py to extract credentials from Authorization header (set by BasicAuthMiddleware) - Add AstrolabeClient for app password provisioning via Astrolabe API - Update oauth_sync.py with dual credential support (app passwords first, then refresh tokens as fallback) - Simplify oauth_tools.py provisioning logic - Add integration tests for app password provisioning and multi-user BasicAuth Features: - Stateless multi-user mode: credentials passed per-request - Optional background sync via app passwords (stored in Astrolabe) - Falls back to refresh tokens if app password not available - Test coverage for provisioning flow and pass-through mode Related: ADR-019 (Multi-user BasicAuth), ADR-020 (Deployment Modes) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 --- nextcloud_mcp_server/auth/astrolabe_client.py | 152 +++++++++++++++++ nextcloud_mcp_server/context.py | 69 ++++++++ nextcloud_mcp_server/server/oauth_tools.py | 160 +++++++----------- nextcloud_mcp_server/vector/oauth_sync.py | 40 +++++ .../test_app_password_provisioning.py | 151 +++++++++++++++++ .../integration/test_multi_user_basic_auth.py | 47 +++++ 6 files changed, 518 insertions(+), 101 deletions(-) create mode 100644 nextcloud_mcp_server/auth/astrolabe_client.py create mode 100644 tests/integration/test_app_password_provisioning.py create mode 100644 tests/integration/test_multi_user_basic_auth.py diff --git a/nextcloud_mcp_server/auth/astrolabe_client.py b/nextcloud_mcp_server/auth/astrolabe_client.py new file mode 100644 index 0000000..54d7080 --- /dev/null +++ b/nextcloud_mcp_server/auth/astrolabe_client.py @@ -0,0 +1,152 @@ +""" +Client for querying Astrolabe Management API for background sync credentials. + +This client uses OAuth client credentials flow to authenticate to Nextcloud +and retrieve user app passwords for background sync operations. +""" + +import logging +import time +from typing import Optional + +import httpx + +logger = logging.getLogger(__name__) + + +class AstrolabeClient: + """Client for querying Astrolabe API for background sync credentials. + + Uses OAuth client credentials flow to authenticate as the MCP server + and retrieve user app passwords that are stored in Nextcloud. + """ + + def __init__( + self, + nextcloud_host: str, + client_id: str, + client_secret: str, + ): + """ + Initialize Astrolabe client. + + Args: + nextcloud_host: Nextcloud base URL (e.g., https://cloud.example.com) + client_id: OAuth client ID for MCP server + client_secret: OAuth client secret + """ + self.nextcloud_host = nextcloud_host.rstrip("/") + self.client_id = client_id + self.client_secret = client_secret + self._token_cache: Optional[dict] = None # {access_token, expires_at} + + async def get_access_token(self) -> str: + """ + Get access token using OAuth client credentials flow. + + Tokens are cached with 1-minute early refresh to avoid expiration. + + Returns: + Access token string + + Raises: + httpx.HTTPError: If token request fails + """ + # Check cache + if self._token_cache and time.time() < self._token_cache["expires_at"]: + logger.debug("Using cached OAuth token for Astrolabe API") + return self._token_cache["access_token"] + + # Discover token endpoint + discovery_url = f"{self.nextcloud_host}/.well-known/openid-configuration" + + async with httpx.AsyncClient() as client: + logger.debug(f"Discovering token endpoint from {discovery_url}") + discovery_resp = await client.get(discovery_url) + discovery_resp.raise_for_status() + token_endpoint = discovery_resp.json()["token_endpoint"] + + logger.debug(f"Requesting client credentials token from {token_endpoint}") + + # Request token using client credentials grant + token_resp = await client.post( + token_endpoint, + data={ + "grant_type": "client_credentials", + "client_id": self.client_id, + "client_secret": self.client_secret, + "scope": "openid", # Minimal scope + }, + ) + token_resp.raise_for_status() + data = token_resp.json() + + # Cache with 1-minute early refresh + expires_in = data.get("expires_in", 3600) + self._token_cache = { + "access_token": data["access_token"], + "expires_at": time.time() + expires_in -
