xBridge MCP

The only MCP server dedicated exclusively to xAI Grok API. Open source. MIT License. Built with AI, for AI.

What is xBridge MCP?

xBridge MCP bridges Claude Code to xAI's Grok API via the Model Context Protocol (MCP). It gives your AI agents 19 tools: chat, web search, X/Twitter search, sessions, multi-step research chains, image generation, image editing, and video generation.

BYOK — Bring Your Own Key. You use your own xAI API key. xBridge never resells or proxies your API usage.

Quick Start

  pip install xbridge-mcp
  XAI_API_KEY=your_key xbridge-mcp

Or with Docker:

  docker pull hrco/xbridge-mcp:latest
  docker run -e XAI_API_KEY=your_key hrco/xbridge-mcp:latest

Claude Code Integration

Add to your MCP config:

  {
    "mcpServers": {
      "xbridge": {
        "command": "xbridge-mcp",
        "env": {
          "XAI_API_KEY": "your_xai_key",
          "XBRIDGE_KEY": "your_xbridge_key"
        }
      }
    }
  }
