Gets the specified forwarding address
AI agents call get_forwarding_address to retrieve information from Gmail 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 configuration data about a forwarding address without creating, modifying, or deleting it. It is a straightforward query operation that reads existing settings. While forwarding address information could be considered sensitive, the risk is purely informational—the tool itself cannot be misused to cause damage beyond exposing existing settings that an authenticated user already has access to view.
From the tool's definition Tool name 'get_forwarding_address' and description 'Gets the specified forwarding address' indicate a retrieval operation with no modification or side effects.
