The Griffin MCP server

We’re releasing our Model Context Protocol (MCP) server in beta. You can find it here on Github. The server gives your AI agents an easy way to interact with the Griffin API. Use the server via any MCP client, including Claude Desktop and code editors like Cursor.

At the moment, our MCP server is limited to our sandbox environment only. We’d love to hear your feedback! And if you’d like to use it in production, get in touch with us at product@griffin.com.

Learn about why we’re releasing our MCP server in this blog post by David, our CEO and Co founder.
