# util_dns_dmarc_policy_parse

DNS DMARC Policy Parse parses DMARC policy, percentage, alignment, and report tags from bounded caller-supplied values without an external provider. Call DNS DMARC Policy Parse before applying a DMARC policy parsed from a caller-supplied record. Returns normalized web evidence, the computed finding, and an explicit pass or advisory status for DNS DMARC Policy Parse as versioned deterministic JSON. Limitation: Evaluates only caller-supplied metadata; it performs no DNS lookup, HTTP request, web search, credential use, or persistent storage.

## Why util_dns_dmarc_policy_parse is rated High

util_dns_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.

## Use case

AI agents invoke util_dns_dmarc_policy_parse to trigger actions in Delx Mcp A2a. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Delx Mcp A2a:
