# Flaim Fantasy

[![MCP Tools](https://img.shields.io/badge/MCP_Tools-10-green.svg)](https://api.flaim.app/mcp)
[![Chrome Web Store](https://img.shields.io/badge/Chrome_Extension-v1.5.2-yellow.svg)](https://chromewebstore.google.com/detail/flaim-espn-fantasy-connec/mbnokejgglkfgkeeenolgdpcnfakpbkn)

Connect your ESPN, Yahoo, and Sleeper leagues, then use Flaim Fantasy in ChatGPT for read-only analysis grounded in your real league. 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** 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 discovered** — Flaim finds supported leagues where possible; confirm and manage them at [flaim.app/leagues](https://flaim.app/leagues)
4. **Pick a default league** for AI conversations
5. **Use Flaim in AI** — open Flaim Fantasy in ChatGPT, or use the optional custom-connector URL with a compatible AI platform (see [Connector Setup](docs/CONNECTOR-DOCS.md))
6. **Optional: 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)
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.

ChatGPT Apps / manual MCP clients → Fantasy MCP Gateway → ESPN/Yahoo/Sleeper Clients → Platform APIs
```

- **Web App (Next.js on Vercel)** — landing/site pages, public live demo, OAuth, league management
- **MCP Gateway (Cloudflare Workers)** — unified endpoint for all platforms and sports
- **Platform Clients (Cloudflare Workers)** — ESPN, Yahoo, Sleeper API normalization
- **Auth Worker (Cloudflare)** — token validation, rate limiting, credential storage
- **Supabase** — user data, OAuth tokens, credentials

## About

Solo indie project — built with care, maintained for the long term. No VC funding, no growth pressure, just a useful tool for fantasy sports fans who use AI.

## Development

```bash
git clone https://github.com/jdguggs10/flaim.git
cd flaim
corepack pnpm install
cp web/.env.example web/.env.local  # add keys
corepack pnpm run dev
```

Root, web, and workers use `pnpm` via Corepack. The Chrome extension is intentionally npm-isolated under `extension/` with its own lockfile and release flow.
