Deep Graph MCP Server by CodeGPT
A Model Context Protocol server that enables seamless interaction with Code Graphs.
MCP.Pizza Chef: diffbot
Deep Graph, built by CodeGPT, maps a GitHub project into a searchable picture of how its pieces connect. Ask in plain English where a feature lives, pull the full source for one function, see what else would break if you changed it, or search the project's own documentation. Public projects listed on deepgraph.co need no account at all. Your own private projects need a free CodeGPT account and a key pasted into the setup.

README
mcp-code-graph FAQ
Which apps does this work in?
Claude Desktop, Claude Code, Cursor, Windsurf, VS Code Copilot, ChatGPT, Gemini CLI, and the CodeGPT extension.
Do I need a key?
Only for your own private projects. Public projects on deepgraph.co work without an account or a key.
Can I use this to understand a codebase I just inherited?
Yes — that is the main use. Ask for an architecture overview, then drill into any part that matters.
How do I add my own project?
Sign up at CodeGPT, upload the repository so a graph is built, then paste your key into the setup snippet.
How hard is the setup?
Light. You paste a short snippet into your AI app's settings, or run one add command in Claude Code.
Does it work on private company code?
Yes, through a CodeGPT account. The repository has to be uploaded and processed there first.
