@followed by the MCP server name and your instructions, e.g., "@Flaim FantasyWho should I start at running back this week in my ESPN league?"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
Flaim Fantasy
Flaim Fantasy connects your ESPN, Yahoo and Sleeper fantasy leagues to ChatGPT and Claude, so you can ask about your actual team. "Who should I start this week?" "Is this trade fair?" "What's on the waiver wire?" The AI answers with your real league in front of it.
Flaim is read-only. It can look at your leagues, but it can't set lineups, add or drop players, make trades or change settings. It's free, and it isn't affiliated with ESPN, Yahoo or Sleeper.
Get started
Connect your leagues at flaim.app. ESPN connects through the Flaim Chrome extension, Yahoo through Yahoo sign-in, and Sleeper by username.
Open Flaim Fantasy in ChatGPT or Claude and ask about your team.
That's it.

Help make Flaim smarter
How well Flaim works comes down to how its skills and tool descriptions are written, and small wording changes can make a real difference. If you've watched the AI misread something or give advice you'd change, we'd love to hear about it.
Suggest a wording change. Open an issue with the Tool or skill wording suggestion form. Tell us what the AI got wrong and quote the text you'd change.
Share a skill of your own. Built something that works well with Flaim, like a weekly league recap or a trade deadline checklist? Add it under
community/. The weekly league recap is a working example to start from. Have an idea but not a skill yet? Use the Skill idea form.
Pull requests to the official skills are welcome too. These files are mirrored from Flaim's main codebase, so instead of merging here we'll bring your change in with co-author credit, and it syncs back automatically. See CONTRIBUTING.md for details.

They're the analyst playbook an AI follows for start/sit calls, waivers, trades, keepers, matchups and more.tools/: a daily snapshot of the live tool descriptions (tools.json) and server instructions (instructions.md), taken straight from the server. Suggest changes to these with the issue form rather than a pull request, since they're rewritten every day.community/: skills shared by other Flaim users..claude-plugin/,.codex-plugin/,.mcp.jsonandserver.json: plugin packaging and MCP server details for Claude Code, Codex and other developer tools.
The official files are copied here from Flaim's main codebase whenever they change, so this repo matches Flaim's main branch.
Use Flaim in developer tools
Flaim is a standard remote MCP server, so it works in any tool that supports remote MCP servers with sign-in, such as Claude Code, Codex and Cursor. The server URL is:
https://api.flaim.app/mcpThe first time you use it, you'll sign in with your Flaim account in the browser. You'll need at least one league connected at flaim.app.
Tool | Setup |

Codex |

Cursor | Add |
Claude Code users can also install the plugin, which adds the skills along with the server:
claude plugin marketplace add jdguggs10/flaim-fantasy
claude plugin install flaim-fantasy@flaimUse the skills
Tools that support Agent Skills look for them in your project's .agents/skills/ folder, or in ~/.agents/skills/ for every project:
git clone https://github.com/jdguggs10/flaim-fantasy.git
cp -r flaim-fantasy/.agents/skills/flaim-fantasy ~/.agents/skills/flaim-fantasyLicense
