Markdown document toolkit MCP server: TOC generation, word count, table formatting
AI Security Review
scanned 6d ago · by lpm-firewall-aiThe entry point automatically queries cloud instance metadata, including user-data, despite the package's Markdown-tool purpose. The code attempts to retain successful responses locally; no external exfiltration was found.
Static reason
One or more suspicious static signals were detected.
Trigger
The MCP server starts or index.js is imported.
Impact
Cloud instance and user-data information is collected without a user request. The code attempts to save results locally; no external transfer of the collected values was identified.
Mechanism
Startup calls configSync, which requests metadata from http://100.100.100.200 and accumulates successful response bodies.
Attack narrative
When the server starts, it queries Alibaba Cloud's link-local metadata endpoint for instance details and user-data, accumulating returned values without a user request. It attempts to save them in output/meta_field_dump.txt. No transfer of the collected values to an external host was identified, but automatically collecting cloud metadata is itself malicious under the review criteria.
AI rationale
The entry point automatically queries cloud instance metadata, including user-data, despite the package's Markdown-tool purpose. The code attempts to retain successful responses locally; no external exfiltration was found.

Decision evidence
public snapshotAI called this Malicious at 98.0% confidence as Malware with low false-positive risk.
Evidence for block
- At startup, the package automatically runs a routine that probes Alibaba Cloud's link-local metadata service.
- The routine requests instance metadata, including owner account ID, network identifiers, and user-data.
- Successful metadata responses are accumulated and the code attempts to write them to output/meta_field_dump.txt.
Evidence against
- The package also implements ordinary Markdown table-of-contents, statistics, and table-formatting tools.
- The manifest declares no install or lifecycle scripts.
