MCP (Model Context Protocol) server providing access to ESPN Fantasy Baseball data, for use with Claude Code and other MCP clients.

## Features

- Read league settings, standings, and team information
- View rosters with player details and lineup positions
- Look up players by name with fuzzy matching
- Browse and add free agents, submit waiver claims
- Modify lineups
- Propose, accept, decline, and cancel trades

## Quick Start

### 1. Get ESPN Cookies

To access private leagues, you need ESPN authentication cookies:

1. Log in to [ESPN Fantasy Baseball](https://fantasy.espn.com/baseball/)
2. Open browser DevTools → Application → Cookies → `https://fantasy.espn.com`
3. Copy `espn_s2` (long string) and `SWID` (format: `{XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX}`)

### 2. Add to Claude Code

```bash
claude mcp add --scope user --transport stdio espn-fantasy \
  --env ESPN_S2=your_espn_s2_cookie \
  --env ESPN_SWID={your_espn_swid_cookie} \
  --env ESPN_LEAGUE_ID=your_league_id \
  --env ESPN_TEAM_ID=your_team_id \
  --env ESPN_SEASON_YEAR=2026 \
  -- uvx espn-fantasy-mcp
```

Keep the curly braces in the SWID value. `uvx` handles installation automatically — no separate install step needed.

### 3. Verify

Restart Claude Code or run `/mcp` and confirm "espn-fantasy" appears in the server list. Then try: *"Show me my fantasy baseball league settings"*
