get_top_news
AI agents call get_top_news to retrieve information from Google News Trends without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or queries news data without modifying, deleting, or executing external operations. It has read-only semantics consistent with the broader server's data retrieval purpose. The lack of a tool-specific description slightly reduces confidence, but the naming convention and server context clearly indicate a safe read operation with minimal blast radius.
From the tool's definition Tool name 'get_top_news' combined with server description stating it 'search and retrieve news articles and trending keywords from Google News' indicates a retrieval operation with no side effects.
