API Mock Server

Security checks across malware telemetry and agentic risk

Overview

This is a normal local API mock server with some dependency and network-exposure caveats, but no artifact evidence of hidden egress, credential use, persistence, or destructive behavior.

Install in a virtual environment, pin or lock dependencies before CI or shared-team use, and run the server with --host 127.0.0.1 unless you deliberately want other machines to reach it. Do not assume webhook simulation exists in this version without reviewing or adding that feature.

Missing User Warnings

Medium
Confidence
90% confidence
Finding
The skill advertises webhook simulation, which strongly implies the ability to send outbound HTTP requests to user-specified endpoints, but it does not disclose that behavior or warn about its effects on external systems. In an agent setting, this omission can lead users to invoke the skill in environments where unsolicited network access, SSRF-like behavior, or unintended calls to production services are risky.
