RECOMMENDED RULE

The rule that runs register_agent safely

PolicyLayer is an MCP gateway: it sits between your AI agents and A2p2a, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For register_agent, this is the rule to start with:

register_agent Rate-limited

register_agent 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.
