Hosted MCP server

Connect Claude or ChatGPT to your notes with one URL and a browser sign-in — nothing to install.

MemNote runs a hosted MCP server. Point an AI assistant at it and the assistant can search, read, and write your notes on your behalf — the same notes you see in the app.

There is nothing to install and no token to copy. You add one URL, sign in with your normal MemNote account in a browser window, and you are connected.

https://mcp.memnote.randomfact.com

The app has this ready to copy: open Settings → Connected AI and tap MCP server URL.

Before you start

You need a MemNote account with a verified email address. If you have not finished that step, see Getting started.
Your assistant needs to support custom MCP connectors over HTTP. On some products that is a paid-plan or developer-mode feature — check your assistant’s own settings if you do not see the option.

Connect Claude

On claude.ai: go to Settings → Connectors, choose Add custom connector, paste the URL above, and sign in to MemNote when the browser window appears. From Settings → Connected AI in the MemNote app, Set up in Claude copies the URL and opens that settings page for you.

In Claude Code, add it from the command line:

claude mcp add --transport http memnote https://mcp.memnote.randomfact.com

The first tool call triggers the browser sign-in.

In Claude Desktop, connectors you have added to your Claude account are available once you are signed in to the same account. If your Claude Desktop build does not offer custom connectors, use the local MCP package instead — it is configured through a file on your own machine and works the same way.

Connect ChatGPT

Go to Settings → Connectors, choose Create, and paste the URL above. Adding a custom connector requires Developer Mode to be enabled on your account. Sign in to MemNote when prompted.

In the MemNote app, Settings → Connected AI → Set up in ChatGPT copies the URL and opens that settings page.

There is also a ready-made MemNoteGPT custom GPT if you would rather not set up a connector yourself.

What the assistant can do

The hosted server exposes 15 tools. They cover your notes, your tags, and the list of your devices:

Tool	What it does
`searchNotes`	Meaning-based search across your notes
`listNotes`	List notes, newest change first, a page at a time
`getNote`	Read one note with its tags
`getNoteHistory`	Read the archived versions of a note
`createNote`	Write a new note
`updateNote`	Change a note (the old version is archived first)
`deleteNote`	Move a note to trash
`addTagToNote`	Put an existing tag on a note
`removeTagFromNote`	Take a tag off a note
`listTags` · `getTag` · `createTag` · `updateTag` · `deleteTag`	Manage tags
`listDevices`	List the devices on your account

A few things worth knowing about how those behave:

searchNotes is semantic, not keyword. It ranks notes by how close their meaning is to your query and only returns reasonably close matches, so a query with no good answer comes back empty rather than returning noise. For literal text matching, use the in-app search described in Search and tags.
Deletes are soft. deleteNote does what the app’s delete does — the note goes to Trash and can be restored. Nothing an assistant does through MCP erases a note permanently.
Edits are versioned. updateNote archives the current version before writing, so an assistant’s edit is always recoverable via getNoteHistory.
Notes an assistant writes sync to your devices like any other note. See Sync and devices.

MemNote uses standard OAuth 2.0. When you add the connector:

Your assistant registers itself with MemNote automatically and sends you to MemNote’s sign-in page in a browser.
You sign in with the same method you use in the app — Google, Apple, or email and password.
MemNote hands the assistant an access token. The assistant stores it; you never see or handle it.

Access tokens are good for 30 days and refresh automatically in the background, so a working connector keeps working without you signing in again.

Your password is never shared with the assistant. The connection is scoped to your own account only — an assistant connected to your MemNote sees your notes and nothing else.

Disconnecting

Remove the connector in the assistant that you added it to (Claude’s or ChatGPT’s connector settings, or claude mcp remove memnote in Claude Code). That stops the assistant from reaching your notes.

MemNote does not currently have an in-app button to revoke a connection, so removing it on the assistant’s side is the way to do it.

If it does not connect

You are asked to sign in over and over. Make sure the browser window completes and returns to your assistant — a blocked pop-up will leave the connection half-finished.
The assistant reports it was not authorized. The connection needs re-authorizing; remove the connector and add it again.
Sign-in itself fails. The connector signs you in to the same MemNote account the app uses, so make sure that account is set up and its email verified — see Getting started.

Local MCP server — the same tools, run from your own machine.
REST API — the HTTP API underneath both of them.
