Harvest

  1.0.2

Overview

This Harvest integration is mostly coherent, but it gives an agent broad ability to create, update, and potentially delete live business records without clear confirmation guidance.

Install only if you trust Membrane and want an agent connected to your Harvest workspace. Before using it, require explicit approval for any create, update, delete, or raw proxy request, and consider pinning or verifying the Membrane CLI package instead of installing @latest globally.

Missing User Warnings

Medium

• Confidence: 88% confidence
• Finding: The skill prominently documents create and update actions for users, clients, tasks, projects, and time entries, but it does not instruct the agent to obtain explicit confirmation before performing mutating operations. In an autonomous or loosely supervised agent environment, this can lead to unintended writes, data corruption, or business-impacting changes in Harvest records.
