pab1it0 chess mcp

A Model Context Protocol (MCP) server for Chess.com's Published Data API.

This provides access to Chess.com player data, game records, and other public information through standardized MCP interfaces, allowing AI assistants to search and analyze chess information.

• Access player profiles, stats, and game records
• Search games by date and player
• Check player online status
• Get information about clubs and titled players
• No authentication required (uses Chess.com's public API)
• Docker containerization support
• Provide interactive tools for AI assistants

The list of tools is configurable, so you can choose which tools you want to make available to the MCP client.

The easiest way to run chess-mcp with Claude Desktop is using Docker. If you don't have Docker installed, you can get it from Docker's official website.

Edit your Claude Desktop config file:

• Mac: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%/Claude/claude_desktop_config.json
• Linux: ~/.config/Claude/claude_desktop_config.json

Then add the following configuration:

{
  "mcpServers": {
    "chess": {
      "command": "docker",
      "args": [
        "run",
        "--rm",
        "-i",
        "pab1it0/chess-mcp"
      ]
    }
  }
}

Alternatively, you can run the server directly using UV. Edit your Claude Desktop config file (locations listed above) and add the server configuration:

{
  "mcpServers": {
    "chess": {
      "command": "uv",
      "args": [
        "--directory",
        "<full path to chess-mcp directory>",
        "run",
        "src/chess_mcp/main.py"
      ]
    }
  }
}

Note: if you see Error: spawn uv ENOENT in Claude Desktop, you may need to specify the full path to uv or set the environment variable NO_UV=1 in the configuration.

Contributions are welcome! Please open an issue or submit a pull request if you have any suggestions or improvements.

This project uses uv to manage dependencies. Install uv following the instructions for your platform:

curl -LsSf https://astral.sh/uv/install.sh | sh

You can then create a virtual environment and install the dependencies with:

uv venv
source .venv/bin/activate  # On Unix/macOS
.venv\Scripts\activate     # On Windows
uv pip install -e .

The project includes a test suite that ensures functionality and helps prevent regressions.

Run the tests with pytest:

# Install development dependencies
uv pip install -e ".[dev]"

# Run the tests
pytest

# Run with coverage report
pytest --cov=src --cov-report=term-missing
