Headline tool. Audits a domain
AI agents call email_auth_audit to retrieve information from Domain Security without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and analyzes security configuration data (email authentication records) for a domain. It queries existing DNS/email records to provide an audit report—a read operation with no side effects, no code execution, and no data modification.
From the tool's definition Tool is described as 'Audits a domain' and is part of a server that 'audit[s] email and domain security' for SPF, DKIM, DMARC checks.

Headline tool. Audits a domain. It is categorised as a Read tool in the Domain Security MCP Server, which means it retrieves data without modifying state.
Register the Domain Security MCP server in PolicyLayer and add a rule for email_auth_audit: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Domain Security. Nothing to install.
email_auth_audit is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the email_auth_audit rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for email_auth_audit. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
email_auth_audit is provided by the Domain Security MCP server (ortamarco/domain-security-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
