Parse raw email headers and report the SPF/DKIM/DMARC verdicts (from Authentication-Results), key fields (From, Subject, Date, Message-ID, Return-Path) and the Received hop chain with per-hop delays and total transit time. Args: - headers (string): the raw email headers. - response_format (
AI agents call analyze_email_headers 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 queries email header data to extract security authentication results and metadata. It has no side effects—it does not modify headers, execute commands, delete data, or commit financial transactions. The action of parsing and reporting is purely informational, making it a Read operation.
From the tool's definition The tool 'Parse raw email headers and report the SPF/DKIM/DMARC verdicts' performs analysis and retrieval of information from provided email headers without modifying, executing code, or triggering external operations.

Parse raw email headers and report the SPF/DKIM/DMARC verdicts (from Authentication-Results), key fields (From, Subject, Date, Message-ID, Return-Path) and the Received hop chain with per-hop delays and total transit time. Args: - headers (string): the raw email headers. - response_format (. 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 analyze_email_headers: 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.
analyze_email_headers 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 analyze_email_headers 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 analyze_email_headers. 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.
analyze_email_headers 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.
