Integrate Navidrome's self-hosted music server into AI agent workflows. Agents can manage music libraries, create playlists, control playback, and search collections through the Subsonic-compatible API and Navidrome's native REST endpoints.

Use jCodeMunch MCP when an agent needs precise symbol lookups, outlines, call-graph context, and targeted source retrieval instead of brute-reading whole files across a large repository.

nb is a command-line and local web note-taking, bookmarking, archiving, and knowledge base application. It stores everything as plain text with Git-backed versioning and syncing, supports wiki-style linking, encryption, tagging, search, and Pandoc-powered import/export — all in a single portable Bash script.
