WHAT IT DOES

What update_template does on TrekMail MCP Server

AI agents use update_template to create or update resources in TrekMail MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your TrekMail MCP Server environment.

RISK

Why update_template is rated Medium

The tool modifies email templates reversibly. While this could impact email communications if templates are maliciously altered, the action is reversible (templates can be corrected) and does not involve destructive deletion, code execution, or financial transactions.

From the tool's definition Tool name 'update_template' and description 'Update an existing email template' indicate modification of existing data without deletion or irreversible consequences.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs update_template safely

PolicyLayer is an MCP gateway: it sits between your AI agents and TrekMail MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For update_template, this is the rule to start with:

update_template Rate-limited

update_template stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
