• 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

Configuration

Requires coinmarket API key.

Development/Unpublished Servers Configuration

``` "mcpServers": { "coinmarket_service": { "command": "uv", "args": [ "--directory", "/path/to/coinmarket_service", "run", "coinmarket_service" ], "env": { "COINMARKET_API_KEY": "" } } } ```

Docker

You can also run the server using Docker:

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

# 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=<insert 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
