msnav

https://github.com/YaroslavZahoruiko/msnav

A pure-Ruby daemon (ruby-lsp style) serving the coderag navigation API — cross-service go-to-definition, references, hover, and CodeLens targets — from a coderag SQLite index. Built to run inside a Ruby devcontainer with no Python: the host builds the index with coderag, the container mounts the shared data dir and runs `msnav up`.
