Connect your fantasy league to ChatGPT and Claude
Yes. ChatGPT can see your fantasy team. Link your ESPN, Yahoo, or Sleeper league once in the FantasyBot app, add FantasyBot in ChatGPT or Claude, and ask about your actual roster, matchup, waiver wire, and trades in plain English. Read-only, no browser extension, works from your phone, across fantasy football, basketball, baseball, and hockey.

More than a connector
A plain connector hands your raw league data to a general-purpose model and lets it guess. FantasyBot runs the analysis first, a positional roster grader, a trade-value model calibrated to the market curve, weekly projections, and full league power rankings, then hands back a computed answer with the numbers behind it. In ChatGPT it renders interactive cards, not just text.
That’s 15 read-only tools: get_my_roster, get_my_team, my_start_sit, get_matchup_outlook, get_waiver_pickups, get_league_power_rankings, get_league_team, my_league_settings, analyze_trade, get_player_value, start_sit_analysis, compare_players, get_player_stats, get_position_rankings, get_trending_players.

Questions
Can ChatGPT see my fantasy team?
Yes. Add FantasyBot in ChatGPT and link your ESPN, Yahoo, or Sleeper league in the FantasyBot app. From then on ChatGPT reads your actual roster, matchup, waiver wire, and league settings when you ask about your team. The same connection works in Claude.
Which fantasy platforms can I connect?
ESPN, Yahoo, and Sleeper, across fantasy football (NFL), basketball (NBA), baseball (MLB), and hockey (NHL). If your league is on another platform, screenshot your roster and FantasyBot reads it instantly.
Do I need a Chrome extension?
No. FantasyBot is a native ChatGPT app and a standard Claude connector, and you link your league from your phone or a browser. Other fantasy connectors still require a desktop Chrome extension for ESPN.
Is it read-only? Can it change my lineup?
It is read-only. FantasyBot can see your roster and give you a verdict, but it can never make a trade, drop a player, or change your lineup. You sign in on ESPN's and Yahoo's own pages, and Sleeper needs only a username. FantasyBot never sees your password.
Is FantasyBot free?
Free to start, with no credit card. Connect a league and you get a full team grade, your league power rankings, and the moves worth making right away, plus chat questions every day. Pro lifts the daily cap and keeps the insights refreshing all season.
Is it safe to connect my fantasy league?
Yes, and the two things worth checking are both true here. Access is read-only, so nothing can change your lineup or make a trade. You sign in on ESPN's and Yahoo's own pages, so FantasyBot never sees or stores your password, and Sleeper needs only a public username. You can revoke access from your Yahoo or ESPN account at any time.
Do I need to create an account?
You need a free FantasyBot account to link a league, because that is what holds the connection between your league and your AI. It takes a few seconds and no credit card. Asking about any player, including rankings, stats and comparisons, works with no account at all.
Can I connect Sleeper and ESPN at the same time?
Yes. You can connect multiple leagues across ESPN, Yahoo, and Sleeper at once, in different sports, and switch between them by name when you ask. A football league on Sleeper alongside a basketball league on ESPN is a normal setup.
Do I need a desktop computer to set this up?
No. The whole setup works from a phone, ESPN included. That is worth checking against alternatives: several fantasy AI connectors require a desktop Chrome extension for ESPN, because private ESPN leagues expose no clean API token. FantasyBot signs you in on ESPN's own page instead.
Do I need to upload screenshots or type out my roster?
No. Once your league is linked, FantasyBot reads your roster directly every time you ask. Screenshots are a fallback for leagues on platforms we do not integrate with yet, not something you need for ESPN, Yahoo, or Sleeper.
How is this different from a plain fantasy MCP connector?
A connector hands your raw league data to a general-purpose model and leaves the reasoning to it. FantasyBot runs the analysis first, roster grades, trade values, weekly projections, and league power rankings, across 15 read-only tools, and returns a computed answer. In ChatGPT it renders interactive cards rather than plain text.
