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