Coinmarket MCP server

Coinmarket MCP Server

Components

Resources

The server implements a few of the Coinmarket API endpoints

Custom coinmarket:// URI scheme for accessing individual notes
Each note resource has a name, description and text/plain mimetype

Tools

The server implements two tools:

get-currency-listings: Get the latest currency listings
get-quotes: Get quotes for tokens
- Takes "slug" (example: bitcoin) or "symbol" (example: BTC) as optional string argument

Copy & paste — that's it

# Build the image
docker build -t coinmarket-service .

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

Before it works, you'll need: COINMARKET_API_KEY

    "command": "docker",
    "args": [
      "run",
      "--rm",
      "-e",

      "coinmarket-service"
    ]
  }
}

Troubleshooting

"spawn uv ENOENT" Error

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

Install uv following the instructions above
Restart your terminal/Claude Desktop after installation
Verify installation: Run uv --version in terminal
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
