WHAT IT DOES

What util_dmarc_policy_parse does on Delx Mcp A2a

RISK

Why util_dmarc_policy_parse is rated High

util_dmarc_policy_parse triggers real processes with real consequences. An agent gone sideways doesn't fire it once. It starts dozens of builds, sends mass notifications, or burns through compute before anyone looks up.

RECOMMENDED RULE

The rule that runs util_dmarc_policy_parse safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Delx Mcp A2a, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For util_dmarc_policy_parse, this is the rule to start with:

util_dmarc_policy_parse Rate-limited

util_dmarc_policy_parse stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
