Flaim Fantasy MCP Server

Flaim Fantasy, at flaim.app, is an app in ChatGPT and a connector in Claude that reads your real ESPN, Yahoo, and Sleeper fantasy leagues so you can ask about your actual team. Advanced users can also add Flaim manually as a custom connector in compatible AI platforms. It is available as a remote MCP endpoint.

Teams that work with sports, cloudflare workers and espn and want a hosted endpoint instead of running a local process. The project is written in TypeScript.
