Project Brain MCP
Allows scanning and querying code from GitHub repositories, providing tools like scan_repo_structure, identify_key_files, explain_auth_flow, and ask_codebase to analyze and understand codebases.
Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g., "@Project Brain MCPScan repo structure of https://github.com/org/project"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
