Check SPF, DKIM, and DMARC email authentication status
AI agents call check_email_authentication to retrieve information from Google Workspace Compliance Audit Tool without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and inspects email authentication configurations (SPF, DKIM, DMARC records/settings) to assess their compliance status. It performs no modifications to data, executes no commands, and causes no side effects. It is a read-only audit function typical of compliance assessment tools.
