How to Set Up and Use Code Research
The Code Research MCP Server gives AI assistants the ability to search developer resources across Stack Overflow, MDN Web Docs, GitHub, npm, and PyPI simultaneously through a single MCP interface. It exposes six distinct search tools — one per platform plus a combined search_all — with caching (1-hour TTL) and rate limit handling built in. Developers use it to let Claude find real code examples, documentation, and package metadata without leaving the chat interface.
Prerequisites
- Node.js 18 or higher (for npx execution)
- An MCP client such as Claude Desktop or Claude Code
- Optional: GitHub Personal Access Token (GITHUB_TOKEN) to avoid rate limiting on GitHub searches
Install via Smithery CLI (recommended)
The easiest way to install is through the Smithery CLI, which handles configuration automatically for Claude Desktop.
npx -y @smithery/cli install @nahmanmate/code-research-mcp-server --client claudeOr add directly to Claude Desktop configuration
Alternatively, add the server directly to your claude_desktop_config.json. No additional environment variables are required for basic use.
Set GitHub token to avoid rate limits (optional)
GitHub searches are rate-limited for unauthenticated requests. Provide a personal access token to increase the rate limit significantly.
export GITHUB_TOKEN=ghp_your_personal_access_token_hereRestart Claude Desktop
After updating the configuration file, restart Claude Desktop to load the new MCP server.
Verify the server is active
In Claude Desktop, look for the MCP tools icon and confirm the code research tools are listed. Ask Claude to search for something simple to confirm connectivity.
Code Research Examples
Client configuration
Add this to your claude_desktop_config.json to use the code research server via npx. Include GITHUB_TOKEN in env to avoid rate limiting on GitHub searches.

"mcpServers": {
"code-research": {

}
}Prompts to try
Use these prompts to search across developer platforms. The search_all tool hits all platforms in parallel for comprehensive results.
- "Search Stack Overflow for how to handle async/await errors in JavaScript"
- "Find MDN documentation for the CSS grid auto-fill property"
- "Search GitHub for Python libraries that parse markdown, filter by language Python"
- "Look up the npm package 'zod' and tell me what it does and its weekly downloads"
- "Search PyPI for HTTP client libraries and compare the top results"
- "Search all platforms for React hooks best practices"Troubleshooting Code Research
GitHub searches return 403 or very limited results
Set the GITHUB_TOKEN environment variable with a GitHub Personal Access Token. Unauthenticated requests are heavily rate-limited. Generate a token at https://github.com/settings/tokens with public_repo scope.
Server not appearing in Claude Desktop after installation
Ensure Node.js 18+ is installed and accessible in your PATH. Try running 'npx -y @nahmanmate/code-research-mcp-server' in a terminal to verify it starts without errors, then restart Claude Desktop.
search_all returns empty results for some platforms
Individual platform APIs may be temporarily unavailable or rate-limited. The server has fallback error handling — use the platform-specific tools (search_stackoverflow, search_npm, etc.) individually to isolate which platform is affected.
