Why League Loom
Yahoo + Claude
Instead of pasting screenshots into a chat, League Loom gives Claude a structured, read-only view of your Yahoo league, so it reasons over your real roster, opponent, categories and available players. Yahoo setup is a sign-in, not a copy-and-paste: Claude opens League Loom's setup when you authorize the connector, you choose Yahoo, and Yahoo asks you to approve read-only access on its own page.
Once the connector is added, League Loom's built-in prompts appear in Claude's connector menu too.
FAQ
Questions
Can Claude really read my Yahoo Fantasy league?
Yes. Once you add League Loom as a connector and sign in with Yahoo during setup, Claude can read your Yahoo rosters, matchups, standings, draft results, available players and recent transactions, then answer from your actual team.
Do I give Claude or League Loom my Yahoo password?
No. You sign in on Yahoo's own page and approve read-only access, so neither Claude nor League Loom sees your Yahoo password. The sign-in Yahoo returns is sealed into your encrypted League Loom connection.
Where is the Add custom connector button in Claude?
Open Settings, then Customize, then Connectors, and choose Add custom connector. Paste https://leagueloom.com/mcp as the Remote MCP server URL, then approve the sign-in. League Loom's setup opens, where you choose Yahoo.
Will Claude change my Yahoo lineup or make moves?
No. League Loom asks Yahoo only for read access, and no League Loom tool can change your league. Claude can recommend a start/sit call or an add; you make the move in Yahoo.
Which Yahoo leagues work?
Current-season Yahoo football, basketball, baseball and hockey leagues, in points, head-to-head category and rotisserie formats. You can add ESPN, Sleeper or Fantrax leagues to the same connection.
What does it cost to connect Yahoo to Claude?
League Loom is free, with no subscription or per-league fee. Fair-use request budgets apply, and Claude has its own plan requirements.
