AI agents call get_news to retrieve information from Borsa MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only queries and retrieves financial news data from KAP (Public Disclosure Platform). It has no capability to create, modify, delete, or execute operations. The read-only nature and informational purpose make this a low-severity Read operation with negligible risk of misuse even if called by an AI agent.
From the tool's definition Tool retrieves KAP news list for BIST stocks or fetches full news content by news_id. The verbs 'get' and 'fetch' indicate data retrieval without modification. No side effects or state changes are mentioned.
