Parameters from the server's own tool schema.
This tool queries and returns a list of existing email templates from Postmark. It performs data retrieval only, with no capability to modify, delete, or execute operations. The blast radius of misuse is minimal—an agent could only discover what templates exist in the account, which is a read-only information disclosure risk.
