## Why mysql_show_foreign_keys is rated Low

This tool queries and retrieves information about foreign key constraints in a MySQL database. It is a read-only operation that does not create, modify, delete, or execute any code. The action is informational only, presenting existing schema metadata. Read operations have minimal blast radius as they cannot cause data loss or unintended side effects.

From the tool's own definition: "Tool name and description indicate a query operation: 'Show foreign key constraints for a table' retrieves metadata about database schema constraints without modifying data."

## Use case

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

## Recommended policy (PolicyLayer)
