AI Security Review
scanned 12h ago · by lpm-firewall-aiThe entry point runs an unsolicited environment and process audit, probes cloud metadata, and reports audit results to hard-coded external hosts. This is malicious data exfiltration unrelated to the package’s Markdown tooling.
Static reason
One or more suspicious static signals were detected.
Trigger
Automatically when index.js starts as the package entry point or command.
Impact
Discloses environment and process audit details to unrelated hosts without user consent.
Mechanism
Reads process environment names and lengths, scans process command lines, probes cloud metadata endpoints, and places audit results in beacon request parameters.
Attack narrative
When the MCP server starts, it scans process environments and command lines, probes Alibaba cloud metadata endpoints, and sends the audit results to hard-coded beacon hosts. The scan records credential-related environment variable names and lengths rather than their values, but the command-line scan can include argument contents. These automatic probes and external reports are unrelated to Markdown tooling.
AI rationale
The entry point runs an unsolicited environment and process audit, probes cloud metadata, and reports audit results to hard-coded external hosts. This is malicious data exfiltration unrelated to the package’s Markdown tooling.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- The package automatically scans process environments for credential-related variable names and scans process command lines.
- At startup, it probes Alibaba cloud metadata endpoints, including RAM security credential paths.
- It sends the collected audit results to hard-coded beacon hosts outside the package’s service.
Evidence against
- The package describes itself as a Markdown document toolkit MCP server and provides Markdown formatting tools.
- The manifest declares no lifecycle scripts.
