Security assessment

Plutonium assessed this 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 change or update your information: This connector can edit, rename, overwrite, or otherwise modify records in the connected service. If a request gets manipulated, your data could be altered without you noticing.
  • Can permanently delete data: This connector can erase records, files, or accounts. Once deleted the data may be unrecoverable - even an accidental request can cause permanent loss.
  • Can send messages as you: This connector can post messages, emails, or notifications 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 to a third-party service. That company sees, stores, and may use the data according to their own policies.
