Get detailed information for a specific contact
AI agents call get_contact_details to retrieve information from macOS MCP Servers without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves contact information without modifying, deleting, or executing actions. It is purely informational and poses minimal risk even if called by an AI agent with incorrect parameters; the worst outcome is exposure of contact details the agent should not access, which is a confidentiality concern but not a Write, Execute, Destructive, or Financial risk.
From the tool's definition Tool name is 'get_contact_details' and description states 'Get detailed information for a specific contact' — this is a query/retrieval operation with no side effects.
