Get and validate SPF record for a domain.
AI agents call get_spf_record to retrieve information from BasicSec MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and validates SPF (Sender Policy Framework) records from DNS, which is a passive read operation. It queries existing security configuration data without creating, modifying, deleting, or executing any operations. The validation aspect is informational analysis only. No side effects or changes to systems occur.
From the tool's definition Tool name 'get_spf_record' and description 'Get and validate SPF record for a domain' indicate retrieval and analysis of existing DNS records with no modification, deletion, or code execution.
