gRPC - Rockbox Daemon

The gRPC server runs on port 6061 and serves both native gRPC and gRPC-Web (so browser clients work without a proxy).

Endpoint — localhost:6061
Schema — published on Buf: buf.build/tsiry/rockboxapis ↗
Buf Studio playground — open ↗

Services

The proto definitions live under proto/ (in buf.build/tsiry/rockboxapis) and generate Rust bindings at crates/rpc/:

Service	Purpose
`PlaybackService`	Transport, current/next track, seek, volume
`LibraryService`	Albums, artists, tracks, search
`PlaylistService`	Live queue + saved playlists
`SettingsService`	Read / update `global_settings`
`SoundService`	Volume + sound parameters
`BrowseService`	Filesystem browsing
`SystemService`	Version, scan, status

Generating clients

Use Buf to generate clients in any supported language:

buf generate buf.build/tsiry/rockboxapis

Or pull the proto files directly:

buf export buf.build/tsiry/rockboxapis -o proto/

Quick test with grpcurl

grpcurl -plaintext localhost:6061 list
grpcurl -plaintext localhost:6061 rockbox.v1alpha1.LibraryService/GetAlbums
grpcurl -plaintext -d '{"id": "<album-id>"}' \
  localhost:6061 rockbox.v1alpha1.LibraryService/GetAlbum

gRPC-Web from the browser

The same port speaks gRPC-Web — useful for browser apps that want a strongly-typed binding without a translating reverse proxy. Use @bufbuild/connect-web or the language equivalent.
