## Why search_news is rated Low

This tool retrieves and queries news data without modifying or executing operations. However, severity is elevated to 'medium' rather than 'low' because the aggregated sentiment ratings, trading signals, and AI impact scores could influence financial decisions if an agent misuses the search results to recommend trades or investments based on manipulated or misinterpreted signals.

From the tool's own definition: "Tool name 'search_news' and server context describe retrieval of cryptocurrency news with filtering by coin, source, and AI metrics."

## Use case

AI agents call search_news to retrieve information from OpenNews MCP without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
