Read field names from a DOL LCA disclosure XLSX file.
AI agents call lca_disclosure_fields to retrieve information from DOL WHD MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves metadata (field names) from a Labor Certification Application disclosure file without creating, modifying, deleting, or executing any operations. It is purely informational and poses minimal risk even if misused by an agent, as it cannot alter data or trigger external actions.
