X API FastMCP Server

Run a local MCP server that exposes the X API OpenAPI spec as tools using FastMCP. Streaming and webhook endpoints are excluded.

Prerequisites

  • Python 3.9+
  • An X Developer Platform app (to get tokens)
  • Optional: an xAI API key if you want to run the Grok test client

Setup (local)

  1. Create a virtual environment and install dependencies:
    • python -m venv .venv
    • source .venv/bin/activate
    • pip install -r requirements.txt
  2. Create your local .env:
    • cp env.example .env
    • Required values (do not skip):
      • X_OAUTH_CONSUMER_KEY
      • X_OAUTH_CONSUMER_SECRET
      • X_BEARER_TOKEN (required for this setup; keep it set even if using OAuth1)
    • OAuth1 callback (defaults are fine):
      • X_OAUTH_CALLBACK_HOST (default 127.0.0.1)
      • X_OAUTH_CALLBACK_PORT (default 8976)
      • X_OAUTH_CALLBACK_PATH (default /oauth/callback)
      • X_OAUTH_CALLBACK_TIMEOUT (default 300)
    • Server settings (optional):
      • X_API_BASE_URL (default https://api.x.com)
      • X_API_TIMEOUT (default 30)
      • MCP_HOST (default 127.0.0.1)
      • MCP_PORT (default 8000)
      • X_API_DEBUG (default 1)
  • Tool filtering (optional, comma-separated):
    • X_API_TOOL_ALLOWLIST
  • Optional Grok test client:
    • XAI_API_KEY
    • XAI_MODEL (default grok-4-1-fast)
    • MCP_SERVER_URL (default http://127.0.0.1:8000/mcp)
  • Optional OAuth2 token generation:
    • CLIENT_ID
    • CLIENT_SECRET
    • X_OAUTH_ACCESS_TOKEN - X_OAUTH_ACCESS_TOKEN_SECRET (optional)
  • Optional OAuth1 debug output:
    • X_OAUTH_PRINT_TOKENS
    • X_OAUTH_PRINT_AUTH_HEADER
  1. Register the callback URL in your X Developer App:
http://<X_OAUTH_CALLBACK_HOST>:<X_OAUTH_CALLBACK_PORT><X_OAUTH_CALLBACK_PATH>

Example (defaults):

http://127.0.0.1:8976/oauth/callback
  1. Start the server:
python server.py

The MCP endpoint is http://127.0.0.1:8000/mcp by default.

  1. Connect an MCP client:
  • Local client: point it to http://127.0.0.1:8000/mcp.
  • Remote client: tunnel your local server (e.g., ngrok) and use the public URL.

Whitelisting tools

Use X_API_TOOL_ALLOWLIST to load a small, explicit set of tools:

X_API_TOOL_ALLOWLIST=getUsersByUsername,createPosts,searchPostsRecent

Whitelisting is applied at startup when the OpenAPI spec is loaded, so restart the server after changes. See the full tool list below before building your allowlist.

OAuth1 flow (startup behavior)

On startup, the server opens a browser for OAuth1 consent and waits for the callback. Tokens are kept in memory only for the lifetime of the server process. Set X_OAUTH_PRINT_TOKENS=1 to print tokens, or X_OAUTH_PRINT_AUTH_HEADER=1 to print request headers.

Available tool calls (allowlist-ready)

Below is the full list of tool calls you can whitelist via X_API_TOOL_ALLOWLIST. Copy any of these into your .env allowlist.

Generate an OAuth2 user token (optional)

  1. Add CLIENT_ID and CLIENT_SECRET to your .env.
  2. Update redirect_uri in generate_authtoken.py to match your app settings.
  3. Run python generate_authtoken.py and follow the prompts.
  4. Copy the printed access token into .env as X_OAUTH_ACCESS_TOKEN. If your flow returns a secret, store it as X_OAUTH_ACCESS_TOKEN_SECRET.

Run the Grok MCP test client (optional)

  1. Set XAI_API_KEY in .env.
  2. Make sure your MCP server is running locally (or set MCP_SERVER_URL).
  3. If Grok is not running on your machine, use ngrok to expose your local MCP server and set MCP_SERVER_URL to the public HTTPS URL that ends with /mcp. Example flow: ngrok http 8000 then MCP_SERVER_URL=https://<id>.ngrok-free.dev/mcp.
  4. Run python test_grok_mcp.py.

Notes

  • Endpoints with /stream or /webhooks in the path are excluded.
  • Operations tagged Stream or Webhooks, or marked with x-twitter-streaming: true, are excluded.
  • The OpenAPI spec is fetched from https://api.twitter.com/2/openapi.json at startup.
