grok-faf-mcp

Persistent project context for xAI Grok

What it is

An MCP server delivering IANA-registered .faf context to xAI Grok over HTTP-SSE. Point your Grok integration at the endpoint, and Grok sees your project DNA — instead of starting every session from zero.

Two ways to use it: hosted at grok-faf-mcp.vercel.app/sse (zero config) or npx grok-faf-mcp locally.

Why it exists

Grok asked for MCP on a URL. This is it.

The first MCP server built specifically for Grok, deployed on Vercel as a URL-first surface. No installation barrier — just a context endpoint Grok can call.
