Milanote by Cotlet

Milanote API and MCP server: connect Milanote to ChatGPT and Claude

Yes, ChatGPT, Claude and other AI agents can work in your Milanote account. That includes Cursor, Codex, OpenClaw and any MCP client, plus automations in n8n, Make and Zapier. Ask in plain words, and the AI adds notes, links and to-do lists to your boards, finds what you saved, sorts cards into columns and exports boards to Markdown. It shows you what it will do first and sends nothing to other people until you say so.

As of November 2026, this repo is the missing piece: 30 Milanote tools for AI assistants and scripts.

What you can ask

*Put these 12 reference links on the Moodboard sub-board of Brand refresh and skip the ones already there.*

*Export my Novel outline board and each chapter sub-board as Markdown into ./outline.*

*Here are my call notes. Add the action items as a to-do list on Q1 campaign with the dates we agreed.*

*Where did I save that note about the color palette?*

Two ways to get it

Cotlet is best for designers, writers and teams who want ChatGPT, Claude or another AI agent to work in Milanote for them, with nothing to install.

Run it yourself

A Milanote API and a Milanote MCP server you run on your own computer, in Python, on the session of your own Google Chrome. 30 of the 31 Milanote tools we run in production at Cotlet: boards, notes, links, to-do lists with due dates, columns, labels, trash, comments, sharing and export.

Milanote has no public API and no official MCP server. This repo gives you both:

• MCP server for Claude Code, Claude Desktop, Cursor, Codex and any MCP client, over stdio or HTTP. Setup
• REST API on http://127.0.0.1:8787/api/v1/milanote, with OpenAPI docs at /docs. Setup
• Python: call("get_board", board_id="1XiqwC1Mir4d4N"), plus 9 ready scripts in examples/.

Questions from Milanote users

Does Milanote have an API? No. Milanote has no public API, no webhooks and no official MCP server (checked October 2026). A public API and an MCP server are open requests on its public roadmap, and the only way to get content out is the Export button, one board at a time. This repo and Cotlet give you 30 Milanote tools as a REST API and an MCP server.

Can I get a Milanote API key? Not from Milanote for your own account. With Cotlet you get your own API key that works with your Milanote account, for scripts, n8n, Make, Zapier or any HTTP client. This repo needs no key: it runs on your computer, on your own Milanote session.

Is there an official ChatGPT integration for Milanote? No. Milanote has no official ChatGPT or Claude connector, and a public API is still an open request on its roadmap. Cotlet is an unofficial one that works today, in the ChatGPT and Claude apps and in any AI agent that takes an MCP server.

How do I connect Milanote to ChatGPT? Sign up at cotlet.dev, sign in to Milanote once in your Cloud Browser there, and add Cotlet to ChatGPT, following the steps in your account. Then ask ChatGPT about your Milanote like you would ask an assistant. ChatGPT needs a server on the internet, so this repo alone, running on your computer, does not connect to ChatGPT.

Can ChatGPT add notes and to-dos to my Milanote boards? Yes, with Cotlet. Paste your call notes or links, and it adds them to the right board as notes, links or a to-do list with due dates, and skips what is already there.

Can I search or export my Milanote boards with AI? Yes, with Cotlet. Ask where you saved something, or export a board and its sub-boards as Markdown, for example into Notion or a document.

Can I automate Milanote with Zapier, Make or n8n? Milanote has no Zapier or Make app. With Cotlet, n8n, Make and Zapier can add notes, links and to-dos to your boards, for example from a form, an email or Slack.

Can I use it from my phone? Yes, with Cotlet: once it is set up, the ChatGPT and Claude apps on your phone can use Milanote for you.

Do I need to be technical? For Cotlet, no: you sign in to Milanote and add Cotlet to ChatGPT or Claude, with step-by-step instructions in your account. This repo is for people who are fine with Python and a terminal.

Is my Milanote account safe? Yes. Neither Cotlet nor this repo sees or stores your Milanote password. You sign in yourself, the way you always do, and the AI works on that signed-in session. Anything that reaches other people asks for your OK first: in Cotlet by default, here through your MCP client.

Is it free? This repo is free, also in your own business. Cotlet is free for 7 days with no card, then one-time credit packs from $29, no subscription. Pricing.

I manage Milanote for several accounts or clients. Does that work? Yes, with Cotlet. Each Milanote login gets its own connection. Write to contact@cotlet.dev and tell us how many accounts you manage.

How it works

AI agent (MCP) / script (REST, Python) ──▶ milanote-mcp on your computer ──your Milanote cookies──▶ milanote.com

▲ milanote-mcp connect ───────┘ reads them once from your Chrome (DevTools Protocol)

1. You sign in to Milanote in your own Chrome, the way you always do.
2. milanote-mcp connect attaches to that Chrome through the Chrome DevTools Protocol, reads the milanote.com cookies and your browser's time zone, and saves them to ~/.config/milanote-api-mcp/session.json, readable by your user only. It never sees or stores your password.
3. Reads are requests to the JSON endpoints of the Milanote web app on app.milanote.com/api. Changes go over the same socket.io channel the web app uses, sent as plain HTTP polling. Everything goes out with your cookies through curl_cffi, which copies Chrome's TLS fingerprint. No headless browser runs.

Milanote's session cookie lasts about a month. When Milanote signs you out, the server reads the cookies from Chrome again, if Chrome is open with remote debugging on.

Requirements

• Python 3.11 or newer.
• Google Chrome 144 or newer, signed in to Milanote. Any Chrome or Chromium works with a debugging port.
• macOS, Linux or Windows.
• Any Milanote plan. A free account stops at 100 cards, and the tools say so when Milanote refuses. Changing a board someone shared with you needs edit access to it.

Install

From PyPI:

uv tool install milanote-api-mcp       # or: pipx install milanote-api-mcp, or: pip install milanote-api-mcp

milanote-mcp --version

MCP clients can also run it with no install: uvx milanote-api-mcp mcp.

From source:

git clone https://github.com/cotletdev/milanote-api-mcp-server.git

cd milanote-api-mcp-server python3 -m venv .venv . .venv/bin/activate # Windows: .venv\Scripts\activate pip install -e . milanote-mcp --version

With uv: uv venv && uv pip install -e ., then uv run milanote-mcp ....

Setting it up with an AI agent (Claude Code, Codex, Cursor)? Open it in this folder and ask it to set up the repo: AGENTS.md tells it every step, and it asks you only for the steps in Chrome.

To update: uv tool upgrade milanote-api-mcp (or pip install -U milanote-api-mcp), from source git pull && pip install -e .. We copy every change of the hosted Milanote tools into this repo.

Connect your Chrome

Option A: your everyday Chrome (recommended)

1. Open chrome://inspect/#remote-debugging in Chrome and switch remote debugging on. Chrome then accepts DevTools connections from programs on this computer, and asks you before each one.
2. Make sure you are signed in at app.milanote.com.
3. Run:

   milanote-mcp connect

1. Chrome asks whether to allow the connection. Click Allow.

You can switch remote debugging off again afterwards. Leave it on if you want the server to pick up a new session by itself after Milanote signs you out.

connect looks for Chrome's DevToolsActivePort file in the default profile folder. For Chrome Beta, Canary or a custom profile folder, pass --profile-dir " ".

Option B: a Chrome with a debugging port

Chrome does not open a debugging port on your default profile, so start a separate one, sign in to Milanote there once, and connect to it:

# macOS

"/Applications/Google Chrome.app/Contents/MacOS/Google Chrome" --remote-debugging-port=9222 --user-data-dir="$HOME/.chrome-milanote"

Linux

google-chrome --remote-debugging-port=9222 --user-data-dir="$HOME/.chrome-milanote"

Windows

"C:\Program Files\Google\Chrome\Application\chrome.exe" --remote-debugging-port=9222 --user-data-dir="%USERPROFILE%\.chrome-milanote"
