WHAT IT DOES

What wa_send_presence does on WA MCP

AI agents invoke wa_send_presence to trigger actions in WA MCP. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why wa_send_presence is rated High

This tool triggers an external operation on WhatsApp — broadcasting a presence/activity status to another party. It doesn't read data, but actively sends a signal to an external service that affects what recipients see. It's not destructive or financial, but it executes an action with real-world side effects (e.g., making the AI appear to be typing or active to another user), which could be used deceptively.

RECOMMENDED RULE

The rule that runs wa_send_presence safely

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

wa_send_presence Rate-limited

wa_send_presence stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
