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.
- LLMs Have a Knowledge Cutoff – They don't have live access to new Stack Overflow content, leading to outdated suggestions.
- 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.
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
- Node.js 18+ (ES2022 support required)
- Stack Exchange API Key (Required)
- Stack Apps Registration (Required for write access)

The server provides several MCP tools for interacting with Stack Overflow:
- 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
- Questions: Post new questions
- Answers: Submit answers to questions
- Comments: Add comments to posts
- Posts: Edit existing posts
The server supports Stack Exchange OAuth 2.0 authentication for write operations:
- Register your application on Stack Apps
- Create a Stack Apps post describing your application
- Configure the OAuth credentials in your .env file
- The server will handle the OAuth flow when write operations are requested
