Manage promotions (discounts) in Pancake POS. Actions: list, get, create, update, delete.
AI agents use manage_promotions to create or update resources in Pancake Pos — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Pancake Pos environment.
An AI agent can call manage_promotions faster than any human can review — one bad instruction and it creates or modifies resources in Pancake Pos by the hundred, each call as confident as the last.
Documented attack patterns abuse exactly the kind of access manage_promotions gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Pancake Pos, and nothing reaches the server without passing your rules. This is the rule we recommend for manage_promotions:
{
"version": "1",
"default": "deny",
"tools": {
"manage_promotions": {
"limits": [
{
"counter": "manage_promotions_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}manage_promotions 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.

Yes. Add a rate_limit block to the manage_promotions rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
