WHAT IT DOES

What wa_delete_message does on WA MCP

AI agents call wa_delete_message to permanently remove resources in WA MCP, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

RISK

Why wa_delete_message is rated Critical

This tool irreversibly deletes messages from a chat, which qualifies it as Destructive rather than Write. While the deletion is scoped to messages sent by the instance (mitigating some risk), the action cannot be reversed and affects all participants in the chat.

From the tool's definition Tool name 'wa_delete_message' and description 'Delete a message for everyone in the chat' explicitly perform irreversible deletion of data.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs wa_delete_message 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_delete_message, this is the rule to start with:

wa_delete_message Hidden

wa_delete_message is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
