Overview
Connected AI Apps allows you to link external AI applications (such as Claude or ChatGPT) to your account using the Model Context Protocol (MCP). This integration grants approved AI tools secure access to read and update your calendars, search meeting notes, and view your booking links. You can review all authorized third-party apps and revoke their access at any time from your settings.
Note
Connected AI apps require you to have at least one calendar account (such as Google or Microsoft) connected to your account so the AI has data to read and manage.

You can connect external AI applications during initial onboarding or at any time through your application settings.
Connecting from Settings
- Open your application settings and navigate to the Connected apps section.
