getSources
AI agents call getSources to retrieve information from News API MCP Server 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 source information from NewsAPI.org without modifying, executing code, deleting data, or moving money. The blast radius of misuse is minimal: an agent could only access public news source metadata. Confidence reduced from 0.95 to 0.85 due to empty description, but the context and sibling tools make the classification reliable.
From the tool's definition Tool name 'getSources' combined with sibling tools 'getTopHeadlines' and 'searchArticles' indicates data retrieval.
