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"
      }
    }
  }
}

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, multi-agent support, and a per request service_tier.
• 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.
• grok_agent — unified agent that mixes files, images, web search, X search, code execution, and server-side image generation. Generated images are written to images/.

Image and video

• generate_image — create or edit images with Grok Imagine (multi-reference editing supported). Pass save=true to write the results to images/ instead of returning temporary URLs.
• generate_video — text-to-video, image-to-video, or video editing with Grok Imagine.
• extend_video — extend an existing generated video with a follow-up prompt.

Files

• upload_file — upload a local document.
• list_files — list uploaded files with sorting.
• get_file — fetch file metadata by ID.
• get_file_content — download file content as text.
• delete_file — delete a file by ID.

Local chat history

• list_chat_sessions — list saved sessions in chats/.
• get_chat_history — get a session's full transcript.
• clear_chat_history — delete a session's local history file.

Models

• list_models — list all Grok language and image models with live pricing.
