xBridge MCP

Grok inside Claude Code. Free. Open source. BYOK.

xBridge MCP is a lightweight, self-hosted MCP server that exposes the full power of xAI Grok (including grok-4.20 models) directly inside Claude Code and other MCP clients.

Why xBridge?

• Full access to Grok-4.20 family (1M context, reasoning, multi-agent); default model grok-4.3
• 19 tools: chat, web/X search, sessions, chains, image gen/edit, video gen, docs, model listing
• Free and open source — self-host with your xAI API key (BYOK), no xBridge call limits
• You control your own API key (BYOK)
• No telemetry, no middleman

Self-host is free forever. A managed Pro tier (prebuilt Docker image + support) is also available — see xbridgemcp.com for pricing.
