Why vibecontrols_configuration_security_presign_evidence is rated Low
Even though vibecontrols_configuration_security_presign_evidence only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.
Attacks that exploit this kind of access
The rule that runs vibecontrols_configuration_security_presign_evidence safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Vibecontrols, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For vibecontrols_configuration_security_presign_evidence, this is the rule to start with:
vibecontrols_configuration_security_presign_evidence is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
