Why validar_rfc is rated Low

Without any rule in front of it, every call an agent makes to validar_rfc happens silently: no trail, no cap, no way to know it misbehaved until something breaks downstream.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs validar_rfc safely

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

validar_rfc Rate-limited

validar_rfc gets a rate cap, and everything else on the server is denied unless you say otherwise.
