upnote-mcp

upnote-mcp is a read-only MCP server for reading local UpNote data from SQLite over stdio.

This is an unofficial project and is not affiliated with, endorsed by, or maintained by UpNote.

Features

• search_notes: search notes by title, body text, or summary

• list_recent_notes: list the most recently updated notes

• list_notes_this_week: list notes updated during the current week

• list_notes_this_month: list notes updated during the current month

• find_notes: combine period, keyword, and tag filters in one call

• open_note: open a note in the UpNote app by note ID

• get_note: fetch the full contents of a note by note ID

• open_notebook: open a notebook in the UpNote app by notebook ID

• list_notebooks: list notebooks with note counts

• create_note: create a new note through UpNote's official URL scheme

• list_tags: list tags

• search_by_tag: list notes for a tag

This project is intentionally read-only. It does not write to the UpNote database. Safe note creation and open actions are performed through UpNote's official URL scheme instead of direct database writes.

Package Name

This package is prepared to be published as @bellx2/upnote-mcp.

Requirements

• macOS

• bun installed on the machine that runs the server

• UpNote desktop app installed

• Default UpNote database path:

~/Library/Containers/com.getupnote.desktop/Data/Library/Application Support/UpNote/upnote.sqlite3

If your database lives somewhere else, set UPNOTE_DB.

Install

bun install

Run

bun run start

For normal use, prefer the published package:

bunx @bellx2/upnote-mcp

or:

npx @bellx2/upnote-mcp

npx support still depends on bun being installed, because this package uses Bun-specific APIs such as bun:sqlite.

For development with file watching:

bun run dev

Environment Variables

• UPNOTE_DB: absolute path to upnote.sqlite3

Example:

export UPNOTE_DB="$HOME/Library/Containers/com.getupnote.desktop/Data/Library/Application Support/UpNote/upnote.sqlite3"

Permissions

On first run, your MCP client may show permission prompts for command execution and local file access.

This is expected because the server:

• launches through bun

• reads your local UpNote SQLite database

• may open the UpNote app for open_note, open_notebook, or create_note

If you deny these permissions, note search and retrieval will not work. After granting access, you may need to restart the MCP server in Cursor or Claude Desktop.
