AI agents call search_google_flights to retrieve information from SearchAPI MCP Agent without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves flight search results from Google Flights. It queries existing data without creating, modifying, deleting, executing code, or committing financial transactions. Even though flights are travel-related, the tool itself only reads/searches available flight information; it does not book, purchase, or modify anything.
From the tool's definition Tool name is 'search_google_flights' and description translates to 'Search Google Flights information'. The verb 'search' combined with the read-only nature of querying flight information indicates data retrieval with no side effects.
