[![MCP Tools](https://img.shields.io/badge/MCP_Tools-9-green.svg)](https://api.flaim.app/mcp)
[![Chrome Web Store](https://img.shields.io/badge/Chrome_Extension-v1.5.1-yellow.svg)](https://chromewebstore.google.com/detail/flaim-espn-fantasy-connec/mbnokejgglkfgkeeenolgdpcnfakpbkn)

Connect your ESPN, Yahoo, and Sleeper leagues to ChatGPT, Claude, and Gemini CLI so you can ask about your actual team, matchup, standings, and waiver wire. Flaim combines live league data with built-in fantasy analyst guidance, so the answers are grounded in your league instead of generic rankings.

Read-only by design. No trades, no drops, no roster changes — just advice.

## How It Works

The **Flaim skill** teaches your AI assistant how to behave like a fantasy analyst — which data to pull, how to interpret it, and how to turn it into useful advice. The **MCP tools** feed it your actual league data. Together, they give a general-purpose AI enough structure to answer like it knows your specific league.

## Get Started

1. **Sign up** at [flaim.app](https://flaim.app)
2. **Connect your platforms** — ESPN via [Chrome extension](https://chromewebstore.google.com/detail/flaim-espn-fantasy-connec/mbnokejgglkfgkeeenolgdpcnfakpbkn), Yahoo via OAuth, Sleeper by username
3. **Leagues auto-discovered** — all your leagues and past seasons are found automatically
4. **Pick a default league** for AI conversations
5. **Install the skill** — recommended for agent-skill tools; copy `.agents/skills/flaim-fantasy/` into your project or home directory (see [The Skill](#the-skill) below)
6. **Add Flaim to your AI** — use the MCP URL in Claude, ChatGPT, or Gemini CLI
7. **Ask questions** — "Who should I start this week?", "What's on the waiver wire?", etc.

## The Skill

The Flaim skill teaches your AI assistant how to behave like a fantasy analyst — when to use which tools, how to interpret league data, and how to turn that context into useful advice.

**Install for Claude Code (or any Agent Skills-compatible tool):**

Place the skill in your project's `.agents/skills/` directory (cross-platform convention) or in `~/.agents/skills/` for global use:

```bash
# Clone or copy the skill directory
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.
