RECOMMENDED RULE

The rule that runs start_instance_browser_task safely

PolicyLayer is an MCP gateway: it sits between your AI agents and ProAgentStore, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For start_instance_browser_task, this is the rule to start with:

start_instance_browser_task Rate-limited

start_instance_browser_task stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

The button opens the PolicyLayer dashboard: create your workspace, connect ProAgentStore, apply this rule, and every start_instance_browser_task call is checked against it from then on.
