A fully local, self-hosted repo index for coding agents (Rust, MIT, runs offline)

If you run local models for coding, feeding them repo context without blowing the context window is half the battle. I built basemind to index a repo locally and serve it over MCP: a code map across 300+ languages, git history and blame, and document RAG over 90+ formats, all on your machine, no cloud.

The query tools return signatures and line numbers instead of whole files, so a structural question costs a fraction of the tokens of reading source, which matters more when your context budget is tight. There's an expand tool to fetch a full function body only when needed.

It runs as an MCP server, a CLI, or a Claude Code plugin over one local index. Rust, MIT.

Honest limitation: the index lags edits between scans (watch mode + rescan handle most of it), and the first cold scan of a big repo takes a bit.

Curious how folks here are wiring repo context into local coding setups.
