+title: MCP Tool Integration
+description: Connect external tools to DocsGPT agents using the Model Context Protocol (MCP) standard.

+
+# MCP Tool Integration
+
+The [Model Context Protocol (MCP)](https://modelcontextprotocol.io/) integration lets you connect external tool servers to DocsGPT. Your agents can then discover and call tools provided by those servers during conversations — for example, querying a CRM, running code, or accessing a database.
+
+## Setup
+
+<Steps>
+
+### Step 1: Configure Environment Variables (Optional)
+
+Only needed if your MCP servers use OAuth authentication:
+
+```env
+MCP_OAUTH_REDIRECT_URI=https://yourdomain.com/api/mcp_server/callback
+```
+
+If not set, falls back to `API_URL/api/mcp_server/callback`.
+
+### Step 2: Add an MCP Server
+
+Go to **Settings** > **Tools** > **Add Tool** > **MCP Server**. Enter the server URL, select an auth type, and click **Test Connection** to verify, then **Save**.
+
+### Step 3: Enable for Your Agent
+
+In your agent configuration, enable the MCP tools you want the agent to use.
+
+</Steps>
+
+## Authentication Types
+
+| Auth Type | Config Fields |
+|-----------|---------------|
+| **None** | — |
+| **Bearer** | `bearer_token` |
+| **API Key** | `api_key`, `api_key_header` (default: `X-API-Key`) |
+| **Basic** | `username`, `password` |
+| **OAuth** | `oauth_scopes` (optional) |
+
+<Callout type="warning">
+For OAuth in production, `MCP_OAUTH_REDIRECT_URI` must be a publicly accessible URL pointing to your DocsGPT backend.
+</Callout>
+
+## API Endpoints
+
+| Endpoint | Method | Description |
+|----------|--------|-------------|
+| `/api/mcp_server/test` | POST | Test a connection without saving |
+| `/api/mcp_server/save` | POST | Save or update a server configuration |
+| `/api/mcp_server/callback` | GET | OAuth callback handler |
+| `/api/mcp_server/oauth_status/<task_id>` | GET | Poll OAuth flow status |
+| `/api/mcp_server/auth_status` | GET | Batch check auth status for all MCP tools |
+
+## Troubleshooting
+
+- **Connection refused** — Verify the URL and that the server is reachable from your backend.
+- **403 Forbidden** — Check credentials and permissions.
+- **Timed out** — Default is 30s; increase timeout in tool config (max 300s).
+- **OAuth "needs_auth" persists** — Verify `MCP_OAUTH_REDIRECT_URI` is correct and Redis is running.

+title: SharePoint / OneDrive Connector
+description: Connect your Microsoft SharePoint or OneDrive as an external knowledge base to upload and process files directly.
+---
+
+import { Callout } from 'nextra/components'
+import { Steps } from 'nextra/components'
+
+# SharePoint / OneDrive Connector
+
+Connect your SharePoint or OneDrive account to upload and process files directly as an external knowledge base. Supports Office files, PDFs, text files, CSVs, images, and more. Authentication is handled via Microsoft Entra ID (Azure AD) with automatic token refresh.
+
+## Setup
+
+<Steps>
+
+### Step 1: Create an App Registration in Azure
+
+1. Go to the [Azure Portal](https://portal.azure.com/) > **Microsoft Entra ID** > **App registrations** > **New registration**
+2. Set **Redirect URI** (Web) to:
+   - Local: `http://localhost:7091/api/connectors/callback?provider=share_point`
+   - Production: `https://yourdomain.com/api/connectors/callback?provider=share_point`
+
+### Step 2: Configure API Permissions
+
+In your App Registration, go to **API permissions** > **Add a permission** > **Microsoft Graph** > **Delegated permissions** and add: `Files.Read`, `Files.Read.All`, `Sites.Read.All`. Grant admin consent if possible.
+
+### Step 3: Create a Client Secret
+
+Go to **Certificates & secrets** > **New client secret**. Copy the secret value immediately (it won't be shown again).
+
+### Step 4: Configure Environment Variables
+
+Add to your `.env` file:
+
+```env
+MICROSOFT_CLIENT_ID=your-azure-ad-client-id
+MICROSOFT_CLIENT_SECRET=your-azure-ad-client-secret
+MICROSOFT_TENANT_ID=your-azure-ad-tenant-id
+```
+
+| Variable | Description | Required | Default |
+|----------|-------------|----------|---------|
+| `MICROSOFT_CLIENT_ID` | Application (client) ID from App Registration overview | Yes | — |
+| `MICROSOFT_CLIENT_SECRET` | Client secret value | Yes | — |
+| `MICROSOFT_TENANT_ID` | Directory (tenant) ID | No | `common` |
+| `MICROSOFT_AUTHORITY` | Login endpoint override | No | Auto-constructed |
+
+<Callout type="warning">
+`MICROSOFT_TENANT_ID=common` (the default) allows any Microsoft account to authenticate. Set this to your specific tenant ID in production.
+</Callout>
+
+### Step 5: Restart and Use
+
+Restart your application, then go to the upload section in DocsGPT and select **SharePoint / OneDrive** as the source. You'll be redirected to Microsoft to sign in, then can browse and select files to process.
+
+</Steps>
+
+## Troubleshooting
+
+- **Option not appearing** — Verify `MICROSOFT_CLIENT_ID` and `MICROSOFT_CLIENT_SECRET` are set, then restart.
+- **Authentication failed** — Check that the redirect URI matches exactly, including `?provider=share_point`.
+- **Permission denied** — Ensure admin consent is granted and the user has access to the target files.
