You can connect Claude and ChatGPT by approving them on a screen, with no key.
Point a client at the MCP endpoint and it asks for access. You approve it in Apioni, choose read-only or read and write, and disconnect it later from Settings.

How it works
- Add the MCP endpoint in the client. It opens an Apioni screen that shows which app is asking and where it sends you back.
- You choose what it can do: read-only, or read and write. Nothing reaches your notes until you allow it.
- Connected apps are listed under Settings → API & MCP, with what each one can do and when it last used your account.
What stays the same
An app reaches only your own notes, and every request goes through the same access rules as the app itself. API keys still work for scripts and any tool where you paste a header yourself. Disconnect an app and it loses access with its next request.
