Integrates with the Cairo Coder API to provide expert-level Cairo and Starknet development assistance, enabling smart contract generation, code refactoring, feature implementation, and contextual guidance based on Cairo/Starknet documentation and best practices.
  1. Register for a Cairo Coder API Key

    • Go to the Cairo Coder API registration or access page. The README does not provide a direct link, so visit the official Kasarlabs Cairo Coder MCP GitHub repository or check their documentation/support channels to find the registration or dashboard where you can obtain an API key.
    • If there is a "Sign Up" or "Get API Key" button, click it and follow the authentication or registration steps.
  2. Copy Your Cairo Coder API Key

    • Once you have access to the developer dashboard or account area, locate your API key (often displayed as a string of letters, numbers, and possibly symbols).
    • Copy this API key. It is required for connecting to the Cairo Coder API.
  3. Add the API Key to FastMCP

    • In the FastMCP connection interface, locate the area to add environment variables (look for your "Install Now" button or ENV section).
    • Create a new entry with the key CAIRO_CODER_API_KEY and paste your copied API key as the value.
  4. Save the Configuration

    • Click the save or confirm button in the FastMCP interface to ensure your changes are applied.
  5. Test the Connection

    • Optionally, run a simple query in your FastMCP environment to verify that the Cairo Coder MCP server is properly connected and authenticated.

Note: If you are using a local or custom Cairo Coder API endpoint and not the public API, you may instead set the CAIRO_CODER_API_ENDPOINT variable to your custom URL, and the API key will not be required.
