Parameters from the server's own tool schema.
This tool performs a read-only query to fetch metadata about news sources from NewsAPI. It has no side effects, does not create, modify, or delete data, and does not execute external code or trigger irreversible changes. The blast radius of misuse is minimal—an agent calling this repeatedly would only result in redundant API queries or rate limiting, with no data loss or financial impact.
From the tool's definition Tool name 'news_get_sources' and description 'Get available news sources from NewsAPI' indicate a retrieval operation that queries and lists available news sources without modifying any data.
