DeusData/codebase-memory-mcp
A single static C binary that indexes a codebase with tree-sitter across 158 languages and keeps a knowledge graph on disk. It exposes 14 MCP tools for search, call-chain tracing, impact checks and dead-code finds, and it configures several coding agents during install.

How we know
Someone outside the project tested it. Their result is below, with a link to the original post. We have not tested it ourselves.
Good for
Developers with large repos whose agents keep reading file after file and want structural questions answered from the graph.
Not for
Small projects, where reading the code is faster. The headline token and speed numbers are the authors' own and were not checked here. Install edits agent config files, so review those first.
