# 🏆 Stack Overflow MCP Server - Hackathon Demo

## 🎯 Project Overview

This project demonstrates a **Stack Overflow MCP (Model Context Protocol) Server** built with Gradio for a hackathon. It provides both a beautiful web interface and an MCP server that AI assistants like Claude can use to programmatically search and analyze Stack Overflow content.

## 🌟 Key Features

### 🔍 **Multiple Search Methods**
- **General Search**: Query-based search with tag filtering
- **Error Search**: Specialized search for error messages and debugging
- **Question Retrieval**: Get specific questions by ID
- **Stack Trace Analysis**: Analyze stack traces to find solutions
- **Advanced Search**: Comprehensive filtering with multiple criteria

### 🎨 **Beautiful Web Interface**
- Clean, modern Gradio interface
- Multiple tabs for different search types
- Quick example buttons for easy testing
- Real-time search results with formatted output
- Support for both Markdown and JSON output formats

### 🤖 **MCP Server Integration**
- Full MCP compatibility for AI assistants
- SSE (Server-Sent Events) endpoint for real-time communication
- 5 available MCP tools for different search scenarios
- Easy integration with Claude Desktop and other MCP clients

## 🎮 How to Test

### Web Interface Testing
1. Visit the [live demo](https://a6f742bf182e4bae9b.gradio.live)
2. Try the different tabs:
   - **General Search**: Use example buttons or enter custom queries
   - **Error Search**: Test with common error messages
   - **Get Question**: Try question ID `11227809`
   - **Stack Trace Analysis**: Use the pre-filled JavaScript example
   - **Advanced Search**: Experiment with complex filters

### MCP Client Testing
Configure your MCP client (like Claude Desktop) with:
```json
{
  "mcpServers": {
    "stackoverflow": {
      "url": "https://c44b366466c774a9d5.gradio.live/gradio_api/mcp/sse"
    }
  }
}
```

## 🏗️ Local Development

```bash
# Clone and setup
git clone <repository>
cd gradio_stack_overflow_client

# Install dependencies
uv add "gradio[mcp]"

# Set your Stack Exchange API key
export STACK_EXCHANGE_API_KEY="your_api_key_here"

# Run the application
uv run python gradio_app.py
```
