WHAT IT DOES

What adb_start_app_monkey does on Renef

AI agents invoke adb_start_app_monkey to trigger actions in Renef. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RECOMMENDED RULE

The rule that runs adb_start_app_monkey safely

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

adb_start_app_monkey Rate-limited

adb_start_app_monkey 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.
