AI agents call get_sector_comparison 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 retrieves and queries financial data (sector peers, valuation ratios like P/E and P/B) for analysis and comparison purposes. It has no side effects, does not modify data, execute code, delete information, or move money. The read-only nature and informational purpose place it firmly in the Read category with low severity.
