Get a specific company phone.
AI agents call get_company_phone to retrieve information from CATS 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 a single piece of contact information (phone number) from a company record in the applicant tracking system. It performs a read-only query with no side effects, no code execution, and no data modification. The blast radius of misuse is minimal—an AI agent could retrieve phone numbers it shouldn't access, but this is a confidentiality concern rather than a destructive or execute-class risk.
From the tool's definition Tool name 'get_company_phone' and description 'Get a specific company phone' indicate retrieval of existing data with no modification or deletion.
