One tool, grok_search(query). Returns an answer and a sources list with x.com links when it pulls from posts. Works in Claude Code, Codex, Cursor, anything that speaks MCP.

Here's why I built it. My agent kept hallucinating current info. Package versions wrong, breaking changes it didn't know about, what people were saying on X about a library. All of it out of date because it only has its training data to work with.

I looked into the X developer API and the hosted X-data MCPs. Both were way too expensive for what I needed.

The Grok CLI already pays for itself. It reads X and the web live. So I wrapped that one capability as an MCP server.

There's a native Claude Code / Grok plugin in the repo too if you prefer slash commands over MCP tools.

On the coding features (review, delegate) - those are mostly redundant with whatever agent you already run. The differentiator is the live X/web data. It's a thin, dependency-free wrapper around your local grok CLI. No tokens stored, read-only. Needs the Grok CLI installed and signed in.

Feedback welcome, especially on whether the tool description makes your agent reach for it at the right time.

I wanted my coding agent to see what is actually current (new releases, breaking changes, what people on X say about a library) instead of guessing from old training data. The X developer API was too expensive for a side project, and hosted X-data MCPs were not cheap either.

So I used the Grok CLI I already pay for, since it can read X and the web in real time, and wrapped that one capability as an MCP server. It is a single tool, grok_search(query), that returns an answer plus a sources list (with x.com links when it uses posts).

Because it is MCP, it is not tied to one agent. It works in Claude Code, Codex, Cursor, or anything that speaks MCP, and there is also a native Claude Code / Grok plugin in the same repo if you prefer slash commands.

One thing that is good to be clear about: this needs the Grok CLI installed and signed in. It is a thin wrapper around that, not a standalone server. If you already pay for Grok, there is no extra cost. The main thing it adds is live X plus web data inside any MCP compatible agent.
