ChatGPT & AI Setup

ChatGPT is the primary Flaim setup path. Flaim Fantasy is available in ChatGPT for read-only fantasy sports analysis.

Last updated May 2026

Start by connecting your fantasy platforms in /leagues. That account setup is what ChatGPT uses when you open Flaim Fantasy. Claude, Perplexity, and Gemini CLI remain optional custom connector and manual MCP setup paths using the URL below.

The setup flow

  1. Connect at least one fantasy platform in /leagues.
  2. Set the default sport or league ChatGPT should use first.
  3. Open ChatGPT and use Flaim Fantasy. For Claude custom connectors, Perplexity custom remote connectors, Gemini CLI, or developer testing, add Flaim with this MCP URL:
https://api.flaim.app/mcp
  1. Authorize Flaim when the browser flow opens.
  2. Start a fresh conversation and ask “What leagues do I have?” to confirm the connection.

ChatGPT

Flaim Fantasy is available in ChatGPT. Connect your leagues in Flaim first, then use ChatGPT for read-only analysis grounded in your real fantasy context.

  1. Connect ESPN, Yahoo, or Sleeper in /leagues.
  2. Set a default league if you have more than one connected league.
  3. Open ChatGPT and use Flaim Fantasy.
  4. Start a fresh ChatGPT conversation and ask what leagues you have. See the sports guide for example prompts.

ChatGPT troubleshooting

  • Flaim does not appear in ChatGPT: search for the exact app name, Flaim Fantasy, and confirm you are using a ChatGPT experience that supports Apps.
  • ChatGPT cannot see any leagues after setup: go back to /leagues and finish platform setup first.
  • ChatGPT does not use Flaim automatically: start a fresh chat and explicitly ask about your connected fantasy league data.

Claude

Flaim is fully live and not in beta. Claude is an optional custom connector setup path, and Claude may still label custom connectors as beta; Free users are limited to one custom connector.

  1. Open Claude connector settings.
  2. Add a custom connector and use https://api.flaim.app/mcp as the server URL.
  3. Authorize Flaim when the browser flow opens.
  4. Start a fresh Claude conversation for your first test. See the sports guide for example prompts.

Claude troubleshooting

  • Authorized successfully but returns no leagues: go back to /leagues and finish platform setup first.
  • Claude does not invoke Flaim on its own: start a fresh chat and be explicit about wanting your connected league data.
  • The Claude UI moved: use Anthropic's latest connector settings flow, then come back to the same MCP URL.

Perplexity

Perplexity is an optional custom remote connector setup path. The key difference is you need to set the auth method to OAuth and the transport to Streamable HTTP.

  1. Open Perplexity's connector settings and choose to add a remote connector.
  2. Use https://api.flaim.app/mcp as the URL.
  3. Set authentication to OAuth.
  4. Set transport to Streamable HTTP.
  5. Authorize Flaim and start a fresh thread.

Perplexity custom remote connectors require HTTPS. In some workspaces, an admin must enable custom remote connectors before members can add them.

For Perplexity's current UI details, check Perplexity's connector docs.

Perplexity troubleshooting

  • Connector exists but returns auth or transport errors: confirm you used OAuth and Streamable HTTP.
  • Connected but sees no leagues: finish platform setup in /leagues first, then start a fresh thread.
  • Multiple stale connectors from testing: delete the extras and keep one clean Flaim connector.

Gemini CLI

Gemini CLI is a manual MCP setup path for terminal-based workflows. It uses the same Flaim MCP URL and OAuth consent flow.

  1. Add Flaim as an MCP server:
    gemini mcp add flaim https://api.flaim.app/mcp --transport http
  2. In Gemini CLI, run /mcp auth flaim and complete the OAuth consent screen.
  3. Start a fresh Gemini CLI session and ask what leagues you have.

How to know it worked

  • ChatGPT shows Flaim Fantasy as available; in manual MCP clients, the client shows Flaim as authorized.
  • A fresh conversation can answer “What leagues do I have?” without failing auth.
  • Follow-up questions about rosters, standings, or matchups work without another auth prompt.

Common issues across all AI apps

  • Authorized before your leagues were linked: finish platform setup first, then start a fresh conversation.
  • AI does not call Flaim automatically: start a fresh chat and explicitly ask about your connected fantasy league data.
  • Keep /leagues handy if you need to reconnect or change your defaults later.
