ESPN, Sleeper, and Fantrax teams woven into one clear answer.

Connect once. Keep asking.

No API keys, spreadsheets, or roster screenshots. One guided setup brings your leagues into any compatible AI tool.

Add one connector

Paste the League Loom URL into Claude, ChatGPT, or another MCP-compatible tool.

Connect your teams

The guided setup finds supported leagues and lets you choose the teams that matter.

Ask in plain language

Ask one question and get an answer grounded in every connected league.

Copy the League Loom URL below.
Open Customize → Connectors, then choose + and Add custom connector. The button below jumps straight there.
Name it League Loom, paste the URL into Remote MCP server URL, and click Add. Nothing under Advanced settings needs changing.
Finish the quick wizard to pick your teams, then ask away.
Copy the League Loom URL below.
In ChatGPT on the web, open Settings → Security and login and turn on Developer mode. ChatGPT only creates an app from a server URL while it is on.
Go to Plugins (chatgpt.com/plugins; some accounts show Apps instead) and select the + button. The button below jumps straight there.
Name it League Loom, paste the URL as the MCP server URL, and choose OAuth for authentication.
Tick I understand and want to continue, click Create, then finish the wizard. In a chat, choose Developer mode from the + menu, select League Loom, and ask away.

ChatGPT asks you to confirm you trust any custom app before it will create one. Developer mode is available on Plus, Pro, Business, Enterprise and Education plans. In a Business workspace only admins can use it, and on Enterprise or Education an admin grants access; in those workspaces the toggle is under Settings → Apps → Advanced settings. ChatGPT runs custom apps on the web only, not in its phone apps.

Ask Meta Muse in chat to create a custom connector using the League Loom server URL below.
Complete /setup on League Loom to choose your leagues and get a connection token. Keep write access off.
Request Muse's secure credential-entry flow and enter the token yourself there. Never paste it into ordinary chat. Review the access request, then confirm your team and season.

Use the guide for a copyable setup prompt and token-handling details. This is the owner's reported workflow; we have not independently completed a Muse connection. Muse Code, Meta's coding agent, adds the same URL as a remote MCP server in its settings file, and the guide covers that too.

Works with any MCP-compatible tool, including Cursor, Cline, Goose, Raycast, and more.
Add a custom MCP server and paste the League Loom URL below as the server address.
Authorize, finish the quick wizard to pick your teams, then ask away.

Any app that speaks the Model Context Protocol can connect, using the same URL shown above.

…/mcp

Every tool asks for the same two things: a name and this URL. Leave any advanced or authentication settings as they are.

Start with a question that saves time

Copy a proven prompt for your weekly review, waiver plan, or lineup check. League Loom supplies the live league context.

The answers before you connect

See how League Loom works with your platforms, sports, AI tools, privacy preferences, and current tool permissions.

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 and no per-league fee. Fair-use request budgets apply. Connect supported ESPN, Sleeper, and Fantrax leagues and ask questions from your AI tool.

Can I set League Loom up on my phone?

Add the connector on a computer: claude.ai or Claude Desktop, or ChatGPT on the web. What works on a phone afterward depends on the assistant. In Claude, a connector added on the web or desktop is also available in the Claude iOS and Android apps, so you can ask about your leagues from your phone. In ChatGPT, custom apps like League Loom currently run only on the web, not in the ChatGPT phone apps. If you start on a phone, use Send to my computer to email or message yourself the link and finish later.

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.

How do I connect League Loom to Muse?

Ask Muse in chat to create a custom connector for https://leagueloom.com/mcp. Complete the League Loom /setup page to choose your leagues. Provide the resulting token yourself through Muse's secure credential-entry flow when offered, then review the access request and verify your connected team. Do not paste the token into ordinary chat. This is the owner's reported workflow; a complete Muse connection has not been independently tested for this guide.

Your connection stays under your control

Your recovery choice
