Github Analyzer

🌟 What This Does

Once installed, you can ask Claude things like:

"Analyze the health of the langchain repo" "Who are the top contributors to pytorch/pytorch?" "Find all open bug issues in fastapi" "Search for TODO comments in microsoft/vscode" "What languages does the Next.js repo use?" "Show me recent commits to the main branch of tensorflow"

Claude uses this MCP server to fetch real GitHub data and give you deep, structured analysis.
