League Loom

League Loom is a read-only Model Context Protocol server that connects an AI assistant to your own fantasy leagues. Add one URL as a custom connector, approve the consent screen, and Claude or ChatGPT can read your rosters, standings, matchups, waivers, and drafts across every league you play in — with every answer grounded in a live API call instead of the model's memory.

There's no account and no database. Platform credentials are sealed into an encrypted token that only you hold, every tool is structurally read-only, and the whole thing runs stateless on serverless functions.
