You can connect Claude, ChatGPT, Cursor and your own scripts to your notes with an API key.
Create a key in Settings and point a tool at the MCP endpoint or the REST API. It can search, read, create and update your notes until you revoke the key.
Open API & MCPYou need to be signed in.
What you can do
- Create a key under Settings → API & MCP. Choose read-only or read & write. The key is shown once; we keep only a hash.
- Add the MCP endpoint to Claude Code, Cursor or any client that speaks Streamable HTTP. It gets four tools: search, fetch, create and update. A read-only endpoint lists just search and fetch.
- Or call the REST API directly: search, list, read, create and update notes, and list folders.
What stays the same
A key only reaches your own notes, and every request goes through the same access rules as the app. Notes created over the API land in your Inbox like any other capture. Revoke a key any time and tools that used it stop with their next request.
