WHAT IT DOES

What bulk_send_notification does on Businys

AI agents use bulk_send_notification to create or update resources in Businys, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Businys environment.

RISK

Why bulk_send_notification is rated Medium

This tool sends notifications (messages/communications) to potentially large groups of clients filtered by practice, status, or explicit IDs. It creates outbound communications, which is a Write action. The severity is high because misuse could result in mass unsolicited or erroneous messages being sent to all clients of an independent professional, damaging client relationships.

RECOMMENDED RULE

The rule that runs bulk_send_notification safely

bulk_send_notification Rate-limited

bulk_send_notification stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
