Luno MCP Server

A Model Context Protocol (MCP) server that provides access to the Luno cryptocurrency exchange API.

This server enables integration with VS Code's Copilot and other MCP-compatible clients, providing contextual information and functionality related to the Luno cryptocurrency exchange.

⚠️ Beta Warning

This project is currently in beta phase. While we've made every effort to ensure stability and reliability, you may encounter unexpected behavior or limitations. Please use it with care and consider the following:

• This MCP server config may change without prior notice
• Performance and reliability might not be optimal
• Not all Luno API endpoints are implemented yet

We welcome feedback and bug reports to help improve the project. Please report any issues you encounter via the GitHub issue tracker.

Features

• Resources: Access to account balances, transaction history, and more
• Tools: Functionality for creating and managing orders, checking prices, and viewing transaction details
• Security: Secure authentication using Luno API keys
• VS Code Integration: Easy integration with VS Code's Copilot features

VS Code Integration

To integrate with VS Code, add the following to your settings.json file (or click on the badge at the top of this README for the docker config).

With Docker

This configuration will make VS Code run the Docker container. Ensure Docker is running on your system.

{
  "servers": {
    "luno-docker": {
      "command": "docker",
      "args": [
        "run", "--rm", "-i",
        "-e", "LUNO_API_KEY_ID=${input:luno_api_key_id}",
        "-e", "LUNO_API_SECRET=${input:luno_api_secret}",
        // Optional: Add debug info
        // "-e", "LUNO_API_DEBUG=true",
        // Optional: Override default API domain
        // "-e", "LUNO_API_DOMAIN=api.staging.luno.com",
        "ghcr.io/luno/luno-mcp:latest"
      ],
      "inputs": [
         {"id": "luno_api_key_id", "type": "promptString", "description": "Luno API Key ID", "password": true},
         {"id": "luno_api_secret", "type": "promptString", "description": "Luno API Secret", "password": true}
      ]
    }
  }
}

Building from source

For MCP client usage: Add one of the config options below to your VS Code settings.json or mcp.json file. The credentials will be provided through VS Code's input prompts.

For direct development: You'll also need to set up environment variables or a .env file as described in the CONTRIBUTING.md file.

For stdio transport

"mcp": {
  "servers": {
    "luno": {
      "command": "luno-mcp",
      "args": [],
      "env": {
        "LUNO_API_KEY_ID": "${input:luno_api_key_id}",
        "LUNO_API_SECRET": "${input:luno_api_secret}"
      },
      "inputs": [
        {"id": "luno_api_key_id", "type": "promptString", "description": "Luno API Key ID", "password": true},
        {"id": "luno_api_secret", "type": "promptString", "description": "Luno API Secret", "password": true}
      ]
    }
  }
}

For SSE transport

"mcp": {
  "servers": {
    "luno": {
      "type": "sse",
      "url": "http://localhost:8080/sse"
    }
  }
}

Installation

Prerequisites

• Go 1.24 or later
• Luno account with API key and secret

Building from Source

1. Clone the repository:

   git clone https://github.com/luno/luno-mcp
   cd luno-mcp
   

2. Build the binary:

   go build -o luno-mcp ./cmd/server
   

3. Make it available system-wide (optional):

   sudo mv luno-mcp /usr/local/bin/
   

Note: When using with MCP clients like VS Code, credentials are provided through the client's input system. For direct development and testing, see the credential setup instructions in CONTRIBUTING.md.

Security Considerations

This tool requires API credentials that have access to your Luno account. Be cautious when using API keys, especially ones with withdrawal permissions. It's recommended to create API keys with only the permissions needed for your specific use case.

Best Practices for API Credentials

1. Create Limited-Permission API Keys: Only grant the permissions absolutely necessary for your use case
2. Never Commit Credentials to Version Control: Ensure .env files are always in your .gitignore
3. Rotate API Keys Regularly: Periodically regenerate your API keys to limit the impact of potential leaks
4. Monitor API Usage: Regularly check your Luno account for any unauthorized activity
