Quick Install

First, go to https://6551.io/mcp to get your API Token.

Claude Code

claude mcp add twitter \
  -e TWITTER_TOKEN=<your-token> \
  -- uv --directory /path/to/twitter-mcp run twitter-mcp

Replace /path/to/twitter-mcp with your local project path, and <your-token> with your Token.

OpenClaw

export TWITTER_TOKEN="<your-token>"
cp -r openclaw-skill/opentwitter ~/.openclaw/skills/

Let AI Review & Install For You

Not sure if this MCP is safe? Paste the prompt below to your AI assistant — it will review the source code first, then install if safe:

Copy this prompt and send it to your AI assistant (replace <project-path> and <your-token> with actual values):

Please review and install the twitter-mcp MCP server for me. The project is at <project-path>.

Steps:
1. Review these files for security:
   - src/twitter_mcp/api_client.py — Confirm it only connects to ai.6551.io, no data sent elsewhere
   - src/twitter_mcp/config.py — Confirm token is only read from local config.json or env vars, no hardcoded secrets or leaks
   - src/twitter_mcp/tools.py — Confirm all tools only perform API queries, no file writes, command execution, or dangerous operations
   - pyproject.toml — Confirm dependencies are only mcp, httpx, no suspicious packages
2. Tell me your conclusion: safe / risky / problematic, with specific reasons
3. If safe, run the install (get Token from https://6551.io/mcp):
   claude mcp add twitter -e TWITTER_TOKEN=<your-token> -- uv --directory <project-path> run twitter-mcp

What Can It Do?

Once connected, just ask your AI assistant:
