WHAT IT DOES

What wa_pin_chat does on WA MCP

AI agents use wa_pin_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_pin_chat is rated Medium

This tool modifies chat metadata (pin state) in a reversible way—pinning and unpinning are toggle operations that do not create, delete, or irreversibly alter data. It is a Write operation with low severity because misuse would only cosmetically reorder the user's chat list without affecting message content, contacts, or financial data.

From the tool's definition Pin or unpin a chat. Pinned chats appear at the top of the chat list.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs wa_pin_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_pin_chat, this is the rule to start with:

wa_pin_chat Rate-limited

wa_pin_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.
