WHAT IT DOES

What wa_pin_message does on WA MCP

RECOMMENDED RULE

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

wa_pin_message Rate-limited

wa_pin_message 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.
