RISK

Why comms_send_message is rated Medium

This tool creates and sends outbound communications (email/WhatsApp) to clients, which modifies external systems and leaves persistent records. It is reversible (messages can theoretically be deleted or unsent, though WhatsApp/email delivery is largely irreversible in practice). However, the requirement for 'confirm: true' suggests safeguards are in place.

From the tool's definition 'Send a single WhatsApp or email message to a specific client' — creates a new message record with communication side effects; 'Use templateKey for predefined templates or customMessage for free text' indicates content generation and dispatch.

RECOMMENDED RULE

The rule that runs comms_send_message safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Servicialo, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For comms_send_message, this is the rule to start with:

comms_send_message Rate-limited

comms_send_message 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.
