Upnote Lens Mcp

upnote-lens-mcp

A hybrid MCP server that lets your AI assistant work with your UpNote notes:

• 🔍 Find & search notes by keyword across titles and bodies.
• 📖 Read & summarize — it returns the actual note text, so the AI can summarize, analyze, or answer questions about what you've written.
• ✍️ Create new notes from the chat.

Under the hood: reads come from the local UpNote SQLite database (read-only), so real content comes back as text; writes go through the upnote:// URL scheme (x-callback-url) and never touch the database.

The write side (URL scheme) is based on chadthornton/upnote-mcp (MIT).

Usage

Once it's registered, just talk to your AI assistant in plain language — it picks the right tool for you. No commands or syntax to memorize. For example:

• "Summarize my UpNote notes about the Q3 roadmap."
• "Find notes where I mentioned Postgres tuning and pull out the key points."
• "What did I write about onboarding last month?"
• "Show me my 5 most recent notes."
• "Create a note titled 'Standup 6/4' with today's three priorities."

Reading, searching, summarizing, and creating all happen through natural conversation.

Requirements

• macOS — fully supported and verified.
• Windows — best-effort. URLs launch through the registered scheme handler, and the default DB path is guessed under %APPDATA%\UpNote\. This path is not verified by the author — if reads fail, set UPNOTE_LENS_DB (see below).
• Python 3.10+ (or just uv, which brings its own).
• UpNote desktop app installed.

Install & register

🤖 Let AI install it (easiest)

Give your MCP client (Claude, etc.) a link to llms-install.md and it will run the steps and set everything up for you.

🧑 Install it yourself

Pick the first option that fits what you already have. Each option includes how to register it in Claude.

Claude Desktop config file (referenced in each option):

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json

Option 1 — with uv (recommended)

Requires uv installed once (brew install uv, or curl -LsSf https://astral.sh/uv/install.sh | sh). After that there's no package install step — uvx downloads, caches, and runs upnote-lens-mcp on demand.

Claude Code:

claude mcp add upnote-lens -- uvx upnote-lens-mcp

Claude Desktop:

{ "mcpServers": { "upnote-lens": { "command": "uvx", "args": ["upnote-lens-mcp"] } } }

Option 2 — with pip (if you don't have uv)

pip install upnote-lens-mcp

Claude Code:

claude mcp add upnote-lens -- upnote-lens-mcp

Claude Desktop:

{ "mcpServers": { "upnote-lens": { "command": "upnote-lens-mcp" } } }

Option 3 — from GitHub over HTTPS (if you don't have pip)

When you can't use PyPI/pip, install straight from the repo with uv. (No uv yet? curl -LsSf https://astral.sh/uv/install.sh | sh.)

Claude Code:

claude mcp add upnote-lens -- uvx --from git+https://github.com/AwesomeHye/upnote-lens-mcp upnote-lens-mcp

Claude Desktop:

{ "mcpServers": { "upnote-lens": { "command": "uvx", "args": ["--from", "git+https://github.com/AwesomeHye/upnote-lens-mcp", "upnote-lens-mcp"] } } }

Tools

Read (queries the local DB → returns real text)

Tool	Description
search_notes(query, limit=20)	Substring search over title/body. Returns id, title, updated time, snippet
get_note(note_id, include_html=False)	Full title + body text of a note (optionally raw HTML)
list_recent(limit=20)	Most recently updated notes
list_notebooks()	Notebooks with note counts and parent
list_notes_in_notebook(notebook_id, limit=50)	Notes inside a notebook
list_tags()	Tags with note counts
list_notes_by_tag(tag_title, limit=50)	Notes carrying a tag

Write (upnote:// URL scheme)

Tool	Description
create_note(title, content, notebook?, markdown=True, new_window=False)	Create a note. content is Markdown by default. notebook matches by name. Tags can't be set (see below)
open_note(note_id, new_window=False)	Open an existing note in the app
open_notebook(notebook_id)	Open a notebook in the app

Tag limitation: UpNote's note/new URL scheme has no tag parameter, and hashtags placed in the body stay as plain text rather than becoming real tags (they only convert to tags when typed in the editor). If you need tags, add them manually in the app after the note is created.

Override the DB path

If the database isn't in the default location (or you're on Windows), point at it with an environment variable:

UPNOTE_LENS_DB=/path/to/upnote.sqlite3

Default paths:

• macOS: ~/Library/Containers/com.getupnote.desktop/Data/Library/Application Support/UpNote/upnote.sqlite3
• Windows (best guess): %APPDATA%\UpNote\upnote.sqlite3
