codebase-memory-mcp

What it does

Full-indexes a repository in milliseconds — the Linux kernel, 28M lines across 75K files, in about three minutes — then answers structural queries fast enough that an agent can ask where something is used instead of reading everything and paying for the privilege. The bigger the codebase, the more the approach earns its keep. Performance figures are the project's own, so measure on your repository. MIT.
