List all email templates
AI agents call list-templates to retrieve information from Mcp Mailtrap without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns existing email templates without modifying, deleting, or executing any actions. It is a straightforward read operation that retrieves data from the Mailtrap email service. The low severity reflects minimal risk even if accessed by an unauthorized agent, as it only exposes template metadata.
