# Can an AI app save notes to PrivacyNotes over MCP?

Yes. MCP (Model Context Protocol) is the standard way AI apps plug in tools, and `privacynotes`, the PrivacyNotes command line interface, can run as one. Add it once, and in any chat you can ask in plain words: "Save a summary of this chat to my notes, tagged meeting." The app calls the save_note tool of `privacynotes`, and the note goes to the Agent folder of your notes, on all your devices after their next sync. The tool can only add notes, so a chat cannot open, change or delete the notes you have. It is part of Pro.

First [set up the `privacynotes` command](https://privacynotes.app/help/command-line) on the same computer and connect it with `privacynotes login`. Then open your AI app's MCP settings, a settings screen or a file such as mcp.json, add this entry under `mcpServers`, and restart the app:

`"privacynotes": { "command": "privacynotes", "args": ["mcp"] }`

The tool takes the Markdown, and optionally a title and tags, with the same limits as `privacynotes save`: 700 KB, 20 tags and a 200-character title. When something stops a save, the tool tells the app in words, so the app can tell you: the command is not connected yet, the note is too large, or the server refused it.

If the app says it cannot start `privacynotes`, give the full path as the command: the one that `which privacynotes` prints, or `where privacynotes` on Windows. Apps started from the Dock or the Start menu often do not see the paths your terminal sees. The command needs [Node.js](https://nodejs.org/en/download) 20 or newer on that computer.
