PolicyLayer is an MCP gateway — it sits between your AI agents and X711io universal gas station market and intelligence, and nothing reaches the server without passing your rules. This is the rule we recommend for x711_email_send:
{
"version": "1",
"default": "deny",
"tools": {
"x711_email_send": {
"limits": [
{
"counter": "x711_email_send_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}x711_email_send 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.
