Notion Workspace MCP

Official proxy MCP — Pages, databases, blocks, search via Notion's official MCP

Live endpoint: https://mcp.aerostack.dev/s/aerostack/mcp-notion

---

Overview

Notion Workspace is a proxy MCP server that forwards requests directly to the official Notion MCP endpoint at https://mcp.notion.com/mcp. All tools are maintained by Notion — new tools are available immediately without any Aerostack update.

Type: Proxy (hosted by Notion)
Auth: Bearer token via NOTION_API_KEY

Important: OAuth Token Required

Notion's MCP endpoint requires an OAuth access token. Internal integration tokens (ntn_...) will NOT work — you'll get a 401 "Invalid token format" error.

How to Get a Notion OAuth Token

1. Go to notion.so/my-integrations
2. Click "New integration" → Set type to Public (not Internal)
3. Fill in the OAuth settings:
   • Redirect URI: Any URL you control (e.g., https://yoursite.com/callback)
   • Integration type: Public
4. Copy your OAuth client ID and OAuth client secret
5. Direct your browser to:

   https://api.notion.com/v1/oauth/authorize?client_id=YOUR_CLIENT_ID&response_type=code&owner=user&redirect_uri=YOUR_REDIRECT_URI
   

6. Authorize the integration → you'll be redirected with a code parameter
7. Exchange the code for a token:

   curl -X POST https://api.notion.com/v1/oauth/token \
     -H "Content-Type: application/json" \
     -u "YOUR_CLIENT_ID:YOUR_CLIENT_SECRET" \
     -d '{"grant_type": "authorization_code", "code": "YOUR_CODE", "redirect_uri": "YOUR_REDIRECT_URI"}'
   

8. Copy the access_token from the response — this is your NOTION_API_KEY

See: developers.notion.com/docs/authorization
