WHAT IT DOES

What import_contacts does on TrekMail MCP Server

AI agents use import_contacts 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 import_contacts is rated Medium

Importing contacts creates or adds data to the system. This is a Write operation because it modifies the contact database by adding new records. The operation is reversible since imported contacts can be individually or bulk deleted.

From the tool's definition Tool description states it imports contacts, which creates new contact records in the system from an uploaded file. The action is reversible (contacts can be deleted), making it Write rather than Destructive.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs import_contacts 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 import_contacts, this is the rule to start with:

import_contacts Rate-limited

import_contacts 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.
