Parameters from the server's own tool schema.
The tool retrieves current service disruption information from PTV (Public Transport Victoria). This is a read-only operation that queries existing data without creating, modifying, deleting, or executing any code. The blast radius of misuse is minimal—an agent could only retrieve publicly available transport disruption data. No financial, destructive, or execute capabilities are evident.
