MCP server that turns AI assistants into Twitter/X power users

What it does

This is a Model Context Protocol (MCP) server that bridges AI assistants to Twitter/X data through the 6551.io API. It exposes a suite of tools—profile lookups, advanced search, quote-tweet tracing, and account monitoring—through a standardized protocol so Claude, Cursor, and similar clients can query X as naturally as they read local files. Under the hood, it is essentially a thin adapter: the heavy lifting is done by the external 6551.io service, not by local scraping logic.

The interesting bit

The real-time WebSocket subscription is the stand-out feature: you can park an AI assistant on a watch list and get pushed events for new tweets, follower changes, profile edits, and even deleted posts. The README also includes a meta-prompt asking your AI to audit the source code for safety before installing—a neat acknowledgment that MCP servers are essentially remote-code execution vectors with extra steps.

Key highlights

• 13 MCP tools covering search, user profiles, KOL follower mapping, and deleted-tweet retrieval
• Real-time monitoring via WebSocket for tweet, follower, and profile-update events
• Broad client support: Claude Code/Desktop, Cursor, Windsurf, Cline, Zed, Continue.dev, Cherry Studio, and OpenClaw
• Event types include crypto-specific signals like CA (contract address) mentions and CA_CREATE
• Includes a “security review” prompt you can paste to your AI to audit api_client.py, tools.py, and dependencies before installation

Caveats

• Requires an API token from the third-party 6551.io service; the README is silent on pricing, rate limits, or data freshness policies
• Heavy crypto and influencer-marketing focus—KOL tracking and contract-address events may be noise if you just want general Twitter search
• Minor doc drift: the project tree claims tools.py holds “8 tools” while the tool table lists thirteen

Verdict

Worth a look if you want your AI assistant to monitor Twitter accounts, track sentiment, or catch deleted posts in real time without writing your own scraper. Skip it if you need official Twitter API guarantees, dislike third-party data intermediaries, or have no interest in crypto-influencer tracking.
