Tools

# Run the container
docker run -e COINMARKET_API_KEY=your_api_key_here coinmarket-service

For Claude Desktop configuration with Docker:

"mcpServers": {
  "coinmarket_service": {
    "command": "docker",
    "args": [
      "run",
      "--rm",
      "-e",
      "COINMARKET_API_KEY=",
      "coinmarket-service"
    ]
  }
}

Troubleshooting

"spawn uv ENOENT" Error

If you see this error, it means `uv` is not installed or not in your PATH:

1. Install uv following the instructions above

2. Restart your terminal/Claude Desktop after installation

3. Verify installation: Run `uv --version` in terminal

4. Update PATH: Make sure uv is in your system PATH

Configuration Issues

• Replace `/path/to/coinmarket_service` with the actual path to your cloned repository
• Ensure your `COINMARKET_API_KEY` is valid
• The path should point to the root directory containing `pyproject.toml`
