WHAT IT DOES

What wa_mute_chat does on WA MCP

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

RISK

Why wa_mute_chat is rated Medium

Muting/unmuting a chat modifies user preferences and notification state but does not create, delete, or irreversibly alter data. The action is entirely reversible (can be unmuted), has minimal blast radius, and does not execute code or move money. This classifies as Write rather than Read (since it modifies state) or more severe categories.

From the tool's definition Tool name 'wa_mute_chat' and description 'Mute or unmute a chat' indicate state modification without data destruction. The optional 'muteUntil' parameter accepts a Unix timestamp, confirming this modifies chat notification settings reversibly.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs wa_mute_chat 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_mute_chat, this is the rule to start with:

wa_mute_chat Rate-limited

wa_mute_chat 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.
