What is Code Research MCP Server?

A Model Context Protocol server that provides tools for searching and accessing programming resources across multiple platforms. It integrates with Stack Overflow, MDN Web Docs, GitHub, npm, and PyPI to help LLMs find relevant code examples, documentation, and packages.

How to use Code Research MCP Server?

Install using Smithery (npx -y @smithery/cli install @nahmanmate/code-research-mcp-server --client claude) or manually by cloning the repository and running npm install && npm run build. Then configure the server in your MCP settings file (e.g., Claude Desktop or VSCode) with the node command pointing to the built index.js. Optionally set a GITHUB_TOKEN environment variable. Once configured, invoke any of the six search tools (e.g., search_stackoverflow, search_github, search_all) via the MCP client.

FAQ from Code Research MCP Server

What are the runtime requirements?

Node.js >= 20.11.0 and npm >= 10.0.0 are required. A GitHub personal access token is optional but recommended to avoid rate limits.

How are results cached?

Results are cached using node-cache with a default TTL of one hour. Cache keys are specific to each query/limit combination, and caching strategies are platform-specific.

Which platforms are integrated?

The server integrates with Stack Overflow, MDN Web Docs, GitHub, npm, and PyPI. Tools are available for each platform individually, plus a combined search tool.

Is a GitHub token mandatory?

No, it is optional. A GitHub personal access token used via the GITHUB_TOKEN environment variable prevents rate limiting when searching GitHub.

Can I run the server in development mode?

Yes, use npm run watch for auto-rebuild on changes, or npm run inspector to launch the MCP Inspector for debugging request/response monitoring.
