WHAT IT DOES

What wa_group_promote does on WA MCP

AI agents use wa_group_promote 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_group_promote is rated Medium

This tool modifies group membership roles by elevating members to admin status. It's a Write operation (reversible - admins can be demoted), but carries high severity because granting admin privileges to users in a WhatsApp group can enable those users to add/remove members, change group settings, and perform other destructive group actions. Misuse by an AI agent could compromise group security and control.

RECOMMENDED RULE

The rule that runs wa_group_promote 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_group_promote, this is the rule to start with:

wa_group_promote Rate-limited

wa_group_promote 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.
