fabrials-mcp

Hosted MCP gateway at https://mcp.fabrials.com. x-search tools call xAI with your API key — there is no shared Fabrials quota. Hetzner Cloud is a separate server with a Cloud API token.

Create a key at console.x.ai. Put it in XAI_API_KEY. A Fabrials fabric virtual key (sk-fb-…) also works: search spends that relay's SuperGrok pool. Do not send a Fabrials cookie or a SuperGrok JWT from ~/.grok/auth.json.
