Security checks across malware telemetry and agentic risk

Overview

This skill appears to fetch Bilibili trending videos as advertised, with no evidence of credential access, persistence, private data use, or destructive behavior.

Before installing, be comfortable with the skill running local Python and making a request to Bilibili's public API when invoked. Ensure Python and the requests dependency come from a trusted environment.

MCP Least Privilege
Confidence
94% confidence
Finding
The skill declares direct tool dispatch to a native tool (`bili_fetch_tool`) in raw argument mode and appears to perform network retrieval, but it does not declare permissions. That creates a transparency and policy-enforcement gap: callers and the platform may not have an accurate view of the skill's effective capabilities, which can enable unintended outbound requests or weaken security review.

Missing User Warnings

Medium
Confidence
93% confidence
Finding
The skill invokes a local Python script via a subprocess but does not disclose that behavior to the user, creating an execution boundary the user may not expect. Even though the command uses a fixed script path and does not interpolate user input, hidden subprocess execution increases risk because the Python script can perform network access, file access, or other side effects outside the visible JavaScript logic.
