Your fantasy leagues, inside Claude
League Loom is a free MCP connector that brings your fantasy leagues into Claude, so you can ask about your roster, standings, matchups, and waivers in plain language. It works across ESPN, Sleeper, and Fantrax, and can read every sport and every league you join at once. The same connector also works with ChatGPT and other MCP-capable AI tools, and it stays read-only.
Pulling your rosters across all three leagues, here are this week's priorities:

Why League Loom
Claude is great at reasoning over your week, but on its own it cannot see your actual leagues. League Loom closes that gap: it connects ESPN, Sleeper, and Fantrax to Claude over MCP, so Claude can read your live rosters, standings, matchups, drafts, and available players instead of guessing. Because it spans multiple providers and sports, you can ask one question and have Claude aggregate across every league at once, from NFL and NBA to MLB and NHL. It is free and strictly read-only, so it never changes your lineups or accounts, and your credentials are sealed into your own encrypted connection rather than stored in a database.
