Flaim Fantasy

Flaim Fantasy, at flaim.app, is an app in ChatGPT and a connector in Claude that reads your real ESPN, Yahoo, and Sleeper fantasy leagues so you can ask about your actual team. Advanced users can also add Flaim manually as a custom connector in compatible AI platforms.

Analysis tools are read-only by design. No trades, no drops, no roster changes — just advice. League refresh can update Flaim's connected-league records so newly available seasons show up.

How It Works

The Flaim skill is an analyst playbook: how to reason about a start/sit call, a waiver claim, a trade, a keeper, or a matchup preview, and what context to gather in what order. The MCP tools feed it your actual league data and carry their own mechanics (parameters, response fields, platform differences) in their descriptions. Together, they give a general-purpose AI enough structure to answer like it knows your specific league.

Get Started

  1. Create your Flaim account at flaim.app.
  2. Connect your fantasy leagues — ESPN via Chrome extension, Yahoo via Yahoo sign-in, or Sleeper by username. Flaim discovers supported leagues and shows them in Your Leagues.
  3. Connect your AI app: Open Flaim Fantasy in ChatGPT or Claude, or follow the optional Perplexity custom-connector path in the connection docs. Public setup docs live at flaim.app/docs.

You are done. Ask questions such as "Who should I start this week?" or "What's on the waiver wire?" Defaults and additional league management are optional after setup.

The Skill

The Flaim skill is the judgment layer. It covers what Flaim is and cannot do, how to gather league context in order, and a playbook per decision type: start/sit, waivers and pickups, trades, keepers and dynasty, matchup previews, draft picks, season history, and multi-league comparisons. Tool mechanics stay in the tool descriptions and the server instructions, which every MCP client reads live, so the skill does not restate them.

Install for Claude Code: the plugin bundles the skills and the MCP server.

claude plugin marketplace add jdguggs10/flaim
claude plugin install flaim-fantasy@flaim

Then run /mcp in Claude Code and choose the Flaim server to sign in. To add only the MCP server, run claude mcp add --transport http flaim https://api.flaim.app/mcp.

Other Agent Skills-compatible tools: place the skill in your project's .agents/skills/ directory or in ~/.agents/skills/ for global use. Claude Code reads .claude/skills/ instead.

cp -r flaim/.agents/skills/flaim-fantasy ~/.agents/skills/flaim-fantasy

The AI will detect and activate the skill automatically when you ask fantasy questions.
