AI agents call sendook_list_webhooks to retrieve information from Sendook without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and lists existing webhook configurations without modifying, deleting, or executing any operations. It is a straightforward read operation that queries webhook data. The severity is low because listing webhooks does not expose sensitive email content or enable direct communication; it only reveals webhook configuration metadata.
