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"
      }
    }
  }
}

Claude Code Integration

Run this command from inside the project directory:

claude mcp add grok-mcp -e XAI_API_KEY=your_api_key_here -- uv run --directory /path/to/Grok-MCP python main.py

Or if you have a .env file with your key:

 claude mcp add grok-mcp -- uv run --directory /path/to/Grok-MCP python main.py

Verify it's registered:

claude mcp list

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"
      ]
    }
  }
}

For stdio:

uv run python main.py

Docker:

docker compose up --build

Mcp Inspector:

mcp dev main.py

Available Tools

Each tool has a full docstring in src/server.py with its arguments and return format. MCP client surfaces those directly, so this list is just a quick map of what's available.

Note: For using images and files, you must provide paths to chat. See Filesystem MCP (Optional) for setup.

Chat and reasoning

• chat — standard chat completion with optional persistent history and multi-agent support.

• chat_with_vision — analyze local or remote images with a Grok vision model.

• chat_with_files — chat grounded on previously uploaded documents.

• stateful_chat — continue a server-side stored conversation via response_id.

• retrieve_stateful_response — fetch a stored response by ID.

• delete_stateful_response — delete a stored response by ID.

Agentic tools

• web_search — autonomous web research with domain filters and citations.

• x_search — autonomous search over X (Twitter) posts, with handle and date filters.

• code_executor — solve tasks by running Python in a sandbox.
