Billsby

Security checks across malware telemetry and agentic risk

Overview

This is a plausible Billsby billing integration, but it gives an agent live billing authority without clear safeguards before charge, cancellation, deletion, or raw API actions.

Install only if you trust Membrane and intend to connect a real Billsby account. Use the least-privileged or sandbox account available, verify the CLI before global installation, and require explicit approval before any charge, cancellation, refund, customer update, customer deletion, or proxy API request.

Missing User Warnings

Medium

Confidence: 91% confidence
Finding: The skill documents destructive operations like canceling subscriptions and deleting customers without requiring confirmation or warning that these actions mutate live billing data. In a production billing context, accidental or premature execution could cause customer harm, revenue loss, or irreversible record changes.

Missing User Warnings

Medium

Confidence: 94% confidence
Finding: The proxy request section enables arbitrary live API calls through authenticated Billsby connections without warning that requests will affect real external systems. This is dangerous because it bypasses safer prebuilt actions and can expose agents to making unintended writes, deletes, or other sensitive operations against billing infrastructure.
