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 memory_batch_update_records:
{
"version": "1",
"default": "deny",
"tools": {
"memory_batch_update_records": {
"limits": [
{
"counter": "memory_batch_update_records_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
