Security assessment

Plutonium assessed this web connector for permissions, capabilities, and security-relevant behavior.

  • Reads your private information: This connector can read data the connected service holds about you - documents, messages, contact lists, source code, customer records, or saved profile details - and pass it back to the AI.
  • Can spend money on your behalf: This connector can complete purchases, bookings, or payments. A misused or hijacked prompt could result in real financial charges before you confirm.
  • Can send messages as you: This connector can post messages, emails, or chat replies on your behalf. Recipients will believe the message came from you, which makes phishing or social-engineering risks higher.
  • Sends your data to outside companies: Anything you share with this connector flows through one or more third-party services. Those companies see, store, and may use the data according to their own policies.
