Why League Loom
Claude can reason across a complicated fantasy week, but it cannot see your leagues on its own. League Loom connects ESPN, Sleeper, and Fantrax over MCP so Claude can use live rosters, standings, matchups, drafts, and available players.
One question can span multiple providers and sports, from NFL and NBA to MLB and NHL. The connector is free. Credentials stay sealed inside your encrypted connection rather than a shared database.
FAQ
Not by itself. Claude has no access to your leagues until you add League Loom, a free MCP connector. Once connected, Claude can read your rosters, standings, matchups, drafts, and available players across ESPN, Sleeper, and Fantrax.
No. League Loom connects over MCP, so it works with Claude, ChatGPT, and other MCP-capable AI tools. You connect once and can use whichever assistant you prefer.
All current tools retrieve or analyze data, and no write-action tools are registered today. A credential alone never grants permission, and any future write tool must require explicit confirmation. Your credentials stay sealed inside your encrypted connection token, with no API keys to manage.
ESPN and Fantrax cover NFL, NBA, MLB, and NHL (ESPN also adds WNBA, and Fantrax adds college football, college basketball, PGA, NASCAR, and EPL). Sleeper covers NFL and NBA only. For MLB and NHL, use ESPN or Fantrax.
