Mailercloud

Security checks across malware telemetry and agentic risk

Overview

This Mailercloud skill is a coherent integration, but it gives an agent broad authenticated ability to change or delete Mailercloud data without clear approval safeguards.

Install only if you intend to let an agent operate Mailercloud through Membrane. Use the least-privileged Mailercloud account available, review generated commands before execution, and require explicit approval before any request that creates, updates, deletes, sends, or changes users, subscribers, campaigns, billing, or account settings.

Missing User Warnings

Medium

Confidence: 91% confidence
Finding: The skill explicitly documents a generic proxy request mechanism supporting POST, PUT, PATCH, and DELETE against the Mailercloud API without requiring confirmation, guardrails, or warnings about destructive effects. In an agent setting, this increases the chance that broad natural-language requests could be translated into state-changing API calls that modify campaigns, subscribers, or account configuration unintentionally.
