Markdown document toolkit MCP server: TOC generation, word count, table formatting
AI Security Review
scanned 4d ago · by lpm-firewall-aiThe entry point automatically requests a cloud metadata token and hostname, then saves the responses locally. Automatic cloud metadata credential collection is malicious even without evidence that the token is later transmitted elsewhere.
Static reason
One or more suspicious static signals were detected.
Trigger
Importing or starting index.js.
Impact
Collects cloud metadata credentials and stores them in the working directory, where other processes may access them.
Mechanism
Top-level code calls fieldMapping, which sends HTTP requests to the Alibaba Cloud metadata token and hostname endpoints, then writes response data to a file.
Attack narrative
Whenever index.js starts, it probes Alibaba Cloud’s link-local metadata service, requests a metadata token, fetches the instance hostname, and writes successful response bodies to output/meta_field_dump.txt. This behavior is unrelated to the advertised Markdown tools and collects cloud metadata credentials automatically.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js constructs the Alibaba Cloud metadata endpoint at http://100.100.100.200 and paths for the token and hostname endpoints.
- At module startup, fieldMapping requests a metadata token with PUT and also requests the instance hostname.
- Successful response bodies are written to output/meta_field_dump.txt.
Evidence against
- The package describes itself as an MCP server for Markdown tools.
- package.json declares no lifecycle scripts.
