What is League Loom?
League Loom is a free AI connector for fantasy sports. It brings live ESPN, Sleeper, and Fantrax league data into Claude, ChatGPT, and other MCP-compatible AI tools so you can ask about rosters, waivers, matchups, standings, drafts, and lineup decisions in plain language.
What is a fantasy sports MCP server?
MCP, the Model Context Protocol, is an open standard that lets AI tools read outside data sources. League Loom is an MCP server for fantasy sports: it gives Claude, ChatGPT, or any MCP compatible tool a set of read tools for live ESPN, Sleeper, and Fantrax league data. Once connected, the AI answers from your real rosters, matchups, standings, and waiver wire instead of guessing from training data.
Is League Loom free?
Yes. The MCP server and connector are free, with no subscription, per-league fee, or usage caps. Connect supported ESPN, Sleeper, and Fantrax leagues and ask questions from your AI tool.
Can I set League Loom up on my phone?
Setting up is easier on a computer, because that is where the connector settings in Claude and ChatGPT are designed to be used. You can still start from a phone browser by opening those settings from our home page, and if you would rather finish later, use Send to my computer to email or message yourself the link. Once the connector is added, asking questions works fine from your phone.
Can I use ChatGPT or Claude for fantasy football?
Yes. League Loom connects ChatGPT, Claude, and other AI tools to your real fantasy football leagues, so answers can use your actual rosters, matchups, standings, and available players instead of generic rankings or pasted snapshots.
Do I have to paste my roster into ChatGPT?
No. ChatGPT and Claude cannot see your fantasy league by themselves, but League Loom gives them a live connection to your leagues. You ask in plain language, and the AI can pull the current league data it needs.
