Grok-MCP

MCP server for xAI's Grok API, can do image understanding, image generation, live web search, and reasoning models.

Features

• Multiple Grok Models: Access to Grok-4.1-Fast-Reasoning, Grok-4.1-Fast-Non-Reasoning, Grok-4-Fast, Grok-3-Mini, and more
• Image Generation: Create images using Grok's image generation model
• Vision Capabilities: Analyze images with Grok's vision models
• Live Web Search: Real time web search with citations from news, web, X, and RSS feeds
• Reasoning Models: Advanced reasoning with extended thinking models (Grok-4.1-Fast-Reasoning, Grok-3-Mini, Grok-4)
• Stateful Conversations: Use this newly released feature to maintain conversation context as id across multiple requests
• Conversation History: Set it on or off to use prior context

Prerequisites

• Python 3.11 or higher
• xAI API key (Get one here)
• Astral UV

Installation

1. Clone the repository:

git clone https://github.com/merterbak/Grok-MCP.git
cd Grok-MCP

2. Create a venv environment:

uv venv
source .venv/bin/activate # macOS/Linux or .venv\Scripts\activate on Windows

3. Install dependencies:

uv sync

Configuration

Claude Desktop Integration

Add this to your Claude Desktop configuration file:

{
  "mcpServers": {
    "grok": {
      "command": "uv",
      "args": [
        "--directory",
        "/path/to/Grok-MCP",
        "run",
        "python",
        "main.py"
      ],
      "env": {
        "XAI_API_KEY": "your_api_key_here"
      }
    }
  }
}

Filesystem MCP (Optional)

Claude Desktop can't send uploaded images in the chat to an MCP tool. The easiest way to give access to files directly from your computer is official Filesystem MCP server. After setting it up you’ll be able to just write the image’s file path (such as /Users/mert/Desktop/image.png) in chat and Claude can use it with any vision chat tool.

{
  "mcpServers": {
    "filesystem": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-filesystem",
        "/Users/<your-username>/Desktop",
        "/Users/<your-username>/Downloads"
      ]
    }
  }
}
