Search Google for a query
AI agents call search_google to retrieve information from MCP Web Research Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and returns search results from Google based on user input. It is a read-only operation with no side effects, no data modification, no code execution, and no destructive or financial impact. The blast radius of misuse is minimal—an agent could only retrieve unwanted search results, which poses no security or operational risk.
From the tool's definition Tool name 'search_google' and description 'Search Google for a query' indicate a query operation that retrieves search results without modifying, executing code, or causing side effects.
