# 🚀 Re-Stack MCP Server – Bridging Stack Overflow & LLMs ## **Introduction** **Re-Stack MCP Server** is a model communication protocol (MCP) server designed to integrate **Stack Overflow** into **LLM-based coding workflows** (Cursor, Windsurf, GPT, Claude, etc.) using the **Stack Exchange API**. It ensures developers have real-time access to the latest solutions while restoring Stack Overflow's crucial **feedback loop**. ## **Why This Matters?** ### 🔥 The Problem 1. **LLMs Have a Knowledge Cutoff** – They don't have live access to **new Stack Overflow content**, leading to outdated suggestions. 2. **The Stack Overflow Feedback Loop is Broken** – Before LLMs, developers would ask questions on Stack Overflow and contribute answers, helping build a global knowledge base. Now, many problems get solved **privately with AI**, **never getting documented**. ### 🚀 The Solution: Re-Stack MCP Server **Re-Stack MCP Server** fixes this by: ✅ **Providing real-time Stack Overflow access** inside LLM-based coding environments ✅ **Prompting users to post questions** when encountering undocumented issues ✅ **Encouraging developers to contribute their solutions** after solving problems ✅ **Fetching the latest answers** from Stack Overflow to **refine LLM responses dynamically** ## **Installation & Usage** ### **Prerequisites** - Node.js 18+ (ES2022 support required) - Stack Exchange API Key (Required) - Stack Apps Registration (Required for write access) ### **Setup** ```bash # Clone the repository git clone https://github.com/jagreetdg/re-stack-mcp.git cd re-stack-mcp # Install dependencies npm install # Configure environment variables cp .env.example .env # Edit .env with your Stack Exchange API credentials # Build the project npm run build # Start the server npm start ``` ### **Environment Variables** ```env STACKEXCHANGE_CLIENT_ID=your_client_id STACKEXCHANGE_API_KEY=your_api_key STACKEXCHANGE_SCOPE=write_access,private_info STACKEXCHANGE_REDIRECT_URI=https://stackexchange.com/oauth/login_success ``` ## **Features & Tools** The server provides several MCP tools for interacting with Stack Overflow: ### Read Operations - **Questions**: Search, fetch, and filter questions - **Answers**: Get answers for specific questions - **Comments**: Fetch comments on posts - **Tags**: Browse and search tags - **Users**: Get user information ### Write Operations (Requires Authentication) - **Questions**: Post new questions - **Answers**: Submit answers to questions - **Comments**: Add comments to posts - **Posts**: Edit existing posts ## **Authentication** The server supports Stack Exchange OAuth 2.0 authentication for write operations: 1. Register your application on [Stack Apps](https://stackapps.com/) 2. Create a Stack Apps post describing your application 3. Configure the OAuth credentials in your .env file 4. The server will handle the OAuth flow when write operations are requested ## **Development** ```bash # Watch mode for development npm run dev # Run linting npm run lint npm run lint:fix # Run tests npm test ``` ## **Project Structure** ``` src/ ├── api/ # Stack Exchange API client ├── auth/ # OAuth authentication ├── server/ # MCP server implementation ├── tools/ # MCP tools (questions, answers, etc.) ├── types/ # TypeScript type definitions └── utils/ # Utility functions ``` ## **Dependencies** - [@modelcontextprotocol/sdk](https://www.npmjs.com/package/@modelcontextprotocol/sdk): MCP server implementation - Express.js: OAuth server - Passport.js: Authentication middleware - TypeScript: Type safety and modern JavaScript features ## **Contributing** Contributions are welcome!
