template_id | string | Yes | Template ID or alias |
Parameters from the server's own tool schema.
This tool queries and retrieves an existing email template from Postmark by its identifier. It performs a read-only operation with no capability to modify, delete, or execute actions. The data retrieved (an email template) is not sensitive enough to warrant higher severity, and the blast radius of misuse is minimal—an agent could only view templates it has access to.
