## Why sg_hdb_resale_stats is rated Low

Even though sg_hdb_resale_stats only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.

## Use case

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