codenib codegraph init /path/to/your/repo

That one command detects the repository languages, installs the pinned package-level graph providers it can manage, builds BM25 plus a source-linked symbol graph, and registers the resulting MCP server with installed Codex and Claude Code clients. It is local, open source, requires no model or cloud, and does not write configuration or indexes into the target repository.

System Architecture

repository change
  -> reuse current views or rebuild affected views
  -> publish a capability-bearing manifest
  -> plan repository queries
  -> deliver bounded, source-linked context

Shortened. The full README is on GitHub.

Nothing above is checked by us. What we check is on the safety report.
