Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs metered_billing safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Plugin Hub, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For metered_billing, this is the rule to start with:

metered_billing Rate-limited

metered_billing 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.
