# Reddit MCP Server

A comprehensive Model Context Protocol (MCP) server for Reddit integration. This server enables AI agents to interact with Reddit programmatically through a standardized interface.

## 🎯 Features

This MCP server provides 6 powerful tools for Reddit interaction:

- **fetchPosts** - Fetch hot posts from any subreddit
- **getComments** - Retrieve comments from specific posts
- **searchPosts** - Search for posts within subreddits
- **postComment** - Post comments on Reddit posts
- **getSubredditInfo** - Get detailed subreddit information
- **postToSubreddit** - Create new text or link posts

## 🚀 Quick Start

### Prerequisites

1. **Reddit API Credentials** - Create a Reddit app at https://www.reddit.com/prefs/apps
2. **Docker** - For containerized deployment
3. **Environment Variables**:
   - `REDDIT_CLIENT_ID` - Your Reddit app client ID
   - `REDDIT_CLIENT_SECRET` - Your Reddit app client secret
   - `REDDIT_USERNAME` - Your Reddit username
   - `REDDIT_PASSWORD` - Your Reddit password
   - `REDDIT_USER_AGENT` - User agent string (optional, defaults to "mcp-reddit-agent/0.1")

### Installation & Setup

#### Method 1: Using Docker (Recommended)

**Linux/macOS:**

```bash
# Clone the repository
git clone https://github.com/KrishnaRandad2023/mcp-reddit
cd mcp-reddit

# Build the Docker image
make build

# Set environment variables
export REDDIT_CLIENT_ID="your_client_id"
export REDDIT_CLIENT_SECRET="your_client_secret"
export REDDIT_USERNAME="your_username"
export REDDIT_PASSWORD="your_password"

# Test the server
make test
```

**Windows (PowerShell/Batch):**

```powershell
# Clone the repository
git clone https://github.com/<my-org>/reddit-mcp
cd reddit-mcp

# Build the Docker image
.\build.ps1 build
# Or use simple batch file: .\build-win.bat build

# Set environment variables
$env:REDDIT_CLIENT_ID = "your_client_id"
$env:REDDIT_CLIENT_SECRET = "your_client_secret"
$env:REDDIT_USERNAME = "your_username"
$env:REDDIT_PASSWORD = "your_password"

# Test the server
.\build.ps1 test
# Or: .\build-win.bat test
```

#### Method 2: Using Task Commands (Docker MCP)

```bash
