## Why check_pincode_serviceability is rated Low

This tool performs a read-only lookup operation against a database of serviceable PIN codes. It returns yes/no serviceability status based on state or district lists, but does not create, modify, delete, or execute any operations. The blast radius of misuse is minimal - worst case would be returning incorrect shipping eligibility information, which is informational only.

From the tool's own definition: "Tool 'check_pincode_serviceability' checks if a PIN code is serviceable - a query operation that retrieves or validates data without modifying anything."

## Use case

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