### Description (declared)

# Yahoo Fantasy MCP Server

A Model Context Protocol (MCP) server that provides access to Yahoo Fantasy Sports data. This server acts as a front-end for the [yahoo_fantasy_api](https://github.com/spilchen/yahoo_fantasy_api) library, allowing AI assistants and other MCP clients to query fantasy league information.

## Features

- Query fantasy league standings and team information
- Retrieve player statistics and projections
- Access matchup data and scoring details
- Get roster information for teams
- Search for players and free agents

## Installation

### From PyPI (when published)

```bash
pip install yahoo-fantasy-mcp
```

### From Source

```bash
git clone https://github.com/yourusername/yahoo_fantasy_mcp.git
cd yahoo_fantasy_mcp
pip install -e .
```

## Prerequisites

Before using this MCP server, you need to set up Yahoo Fantasy API credentials:

1. Register your application at [Yahoo Developer Network](https://developer.yahoo.com/apps/)
2. Obtain your `consumer_key` and `consumer_secret`
3. Set up OAuth2 authentication using one of the methods below

## Configuration

There are two ways to authenticate with Yahoo's API:

### Option 1: Using oauth2.json (Recommended)

Create an `oauth2.json` file with your Yahoo OAuth credentials. You can generate this file using the [yahoo_fantasy_api](https://github.com/spilchen/yahoo_fantasy_api) authentication flow:

```python
from yahoo_oauth import OAuth2

# This will prompt you to authorize via browser
sc = OAuth2(None, None, from_file='oauth2.json')
```

The `oauth2.json` file will look like:

```json
{
  "access_token": "...",
  "consumer_key": "your_consumer_key",
  "consumer_secret": "your_consumer_secret",
  "guid": "...",
  "refresh_token": "...",
  "token_time": 1234567890.123456,
  "token_type": "bearer"
}
```

### Option 2: Using Environment Variables

Set the following environment variables:

```bash
export YAHOO_CLIENT_ID="your_consumer_key"
export YAHOO_CLIENT_SECRET="your_consumer_secret"
```
