Every change is saved as a version, so you can always undo it
The connector can't delete a resume, and you can disconnect anytime

Questions

Does it cost extra?

What exactly is a connector?

It gives Claude secure access to one app, here your 123Resume account, so it can read and update your resumes when you ask. It's built on MCP, the open standard Claude uses to connect to apps.
