the-librarian

Skill librarian MCP server — every installed skill costs tokens; the librarian keeps your whole collection out of agent context. Agents ask, get the few right skills for the task, and their outcomes curate the collection. Fully local: Ollama + SQLite + optional Apple Intelligence. Maintained by aka-kika on GitHub, where it has earned 31 stars from the community.

It's actively developed around agent-skills, apple-intelligence, claude-code, and is a solid reference for anyone building with these tools.
