AI agents call search_news_info to retrieve information from MCP2Brave without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves news information via the Brave News API. Search operations are read-only with no side effects, no code execution, no data modification, and no financial transactions. The low severity reflects minimal risk even if misused—an agent could only retrieve news data, which has no destructive potential.
