Connect your ESPN, Yahoo, or Sleeper fantasy league to Claude

Flaim Fantasy is a Claude connector (also called an app or plugin) that connects your ESPN, Yahoo, or Sleeper fantasy football league to Claude. It's a free, read-only integration: Claude can read your real roster, matchups, standings, and free agents, but can't change anything. Fantasy baseball, basketball, and hockey work too on ESPN and Yahoo, and basketball on Sleeper.

Claude connector

Three steps to your league in Claude

  1. Step 1

    Connect your ESPN, Yahoo, or Sleeper leagues to Flaim.

  2. Step 2

    Open Flaim Fantasy in Claude's connector directory and choose Connect.

  3. Step 3

    Authorize your Flaim account, then ask what fantasy leagues you have.

Claude shows Flaim Fantasy as Connected when it is ready. To check, start a new conversation and ask, “What fantasy leagues do I have?”

Claude's connector doesn't include Flaim's fantasy skill yet. Claude still gets your league data and a short set of advice rules from Flaim.

What the skill does, and where it runs

Claude questions

Is there a Claude connector for my fantasy league?

Yes. Flaim Fantasy is in Claude's connector directory. It reads your ESPN, Yahoo, and Sleeper leagues, it's read-only, and it's free.

Is there a Claude connector for ESPN, Yahoo, or Sleeper fantasy football?

Yes. Flaim Fantasy works with all three. ESPN sets up once with the free Flaim Chrome extension on a computer, and private leagues work. Yahoo connects with a Yahoo sign-in and Sleeper with your username, with no extension for either. ESPN and Yahoo cover football, baseball, basketball, and hockey. Sleeper covers football and basketball.

Can Claude see my fantasy football roster?

Yes, once your league is connected to Flaim and Flaim Fantasy is added to Claude. Claude can read your roster, matchup, standings, free agents, and recent moves, which Flaim fetches from ESPN, Yahoo, or Sleeper when you ask. It's read-only, so Claude can't set your lineup or make moves.

Claude doesn't use Flaim on its own

Check that Claude shows Flaim Fantasy as Connected, then ask Claude to use Flaim for your fantasy league question.
