Luno MCP Server

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

This server enables integration with Claude Code/VSCode/Cursor (and other MCP-compatible clients), providing contextual information and functionality related to the Luno cryptocurrency exchange.

Getting started

Some tools require your Luno API key and secret. Get these from your Luno account settings.

Standard config (Docker) works with most MCP clients:

{
  "mcpServers": {
    "luno": {
      "command": "docker",
      "args": [
        "run", "--rm", "-i",
        "-e", "LUNO_API_KEY_ID=YOUR_API_KEY_ID",
        "-e", "LUNO_API_SECRET=YOUR_API_SECRET",
        "ghcr.io/luno/luno-mcp:latest"
      ]
    }
  }
}

Examples

Working with wallets

You can ask your LLM to show your wallet balances:

What are my current wallet balances on Luno?

Trading

You can ask your LLM to help you trade:

Create a limit order to buy 0.001 BTC at 50000 ZAR

Transaction history

You can ask your LLM to show your transaction history:

Show me my recent Bitcoin transactions

Market Data

You can ask your LLM to show market data:

Show me recent trades for XBTZAR

What's the latest price for Bitcoin in ZAR?

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.

Write Operations Control

By default, the MCP server runs in read-only mode — create_order, cancel_order, and convert are not exposed. To enable them, set ALLOW_WRITE_OPERATIONS to true, 1, or yes. See the config examples above for where to add this flag.

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
5. Use Read-Only Mode by Default: Only enable write operations when specifically needed
