Cozi MCP

The trigger was a paper printout of doctor appointments stuck to the fridge. Adding each one to our shared Cozi calendar meant a stack of taps through a UI my family had quietly given up on, and so we'd quietly stopped adding things we should have. I asked the obvious question: why can't I take a picture of this and have AI do the extraction.

The first cut was a Python client, py-cozi-client, which still ships on its own. Then I converted the project to Node so deployment could be one command instead of a virtualenv: an installable .mcpb bundle for Claude Desktop, an npm package, a hosted listing on Smithery for everyone else, and the whole thing open sourced. Vibe coded with AI tooling, top to bottom.

Unofficial: Cozi MCP is not built, sponsored, or endorsed by Cozi, the family-organizer service it talks to.
