Your league's sidekick in chat
Your AI sees your league's real standings, results and schedule, so it can do more than look things up. It can make things for your group chat.
- “Make power rankings for my league, with a funny line for each team.”
- “What would it take for me to win the league?”
- “Which games this weekend matter most for me?”
- “Write a fun recap of this week for my group chat.”
- “Who had the best week in my league, and why?”
- “Explain how I got my points this week like I'm 10.”
Answers come from your league's real data. Your AI writes the fun part.

How it works
Server address
https://windomsports.com/api/mcp/mcp
You connect from inside your assistant. It asks you to sign in to Windom Sports and approve access once. Everything stays inside your own account. Only two things change anything: joining a league and saving your picks.
What it can do
- My leagues: Every league you're in, with sport, format, your rank and what needs doing next.
- Find a league: Public leagues open to join right now.
- Join a league: By invite code, or a public league by its exact name.
- See pick options: In select leagues: the pick rules, lock time, your current picks and who you can still choose.
- Save my picks: In select leagues: updates your picks before they lock, with the same rules as the site.
- How am I doing: Standings, your rank and points, and recent results for your teams.
- How scoring works: How a league turns results into points, with worked examples.
It can't change league settings or show anyone's picks before they lock, and it can't reach anyone else's account. Picks only save in select leagues; draft leagues pick their teams in the draft on Windom Sports. Free to play. No money, no prizes, no wagering.
To disconnect, go to Account and tap Disconnect. It stops working right away. You can also remove Windom Sports in your assistant's own settings.
If something isn't working
- Your assistant can't see your leagues: check you signed in with the same email you use on Windom Sports.
- It says it can only read your leagues: reconnect from Claude or ChatGPT itself. Other apps can read but not save picks.
- Picks won't save: they may have locked. Ask for the pick board to see the lock time.
- Still stuck: disconnect in Account, connect again, or write to support.
