PolicyLayer is an MCP gateway — it sits between your AI agents and Awslabs Amazon Sns Sqs, and nothing reaches the server without passing your rules. This is the rule we recommend for schedule_stop_application:
{
"version": "1",
"default": "deny",
"tools": {
"schedule_stop_application": {
"limits": [
{
"counter": "schedule_stop_application_rate",
"window": "minute",
"max": 60,
"scope": "grant"
}
]
}
}
} schedule_stop_application gets a rate cap, and everything else on the server is denied unless you say otherwise.
