This Forum3 Learning Hub guide explains what a Claude connector is and how read and write permissions work. It describes the three settings available for each kind of action: Always allow, Needs approval, and Blocked.

The guide covers five questions to ask before connecting an app: what specific job the connector should do, whether it needs read-only or write access, whether you are comfortable with Claude seeing everything you can see in the app, who built the connector, and who owns it and reviews it. It also explains prompt injection and why anything that makes changes should stay on Needs approval.

It notes that Research mode can take actions without checking in again, so changes should be turned off before using it.
