AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The 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. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-10-31T16:48:26.945Z - **Finished:** 2026-10-31T16:49:08.963Z - **Download time:** 772 ms - **Static scan time:** 45 ms - **AI review time:** 41201 ms - **Total time:** 42018 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** Automatically probes cloud instance metadata and saves the token response and hostname. - **Trigger:** Importing or starting index.js. - **Impact:** Collects cloud metadata credentials and stores them in the working directory, where other processes may access them. - **Evidence paths:** index.js - **Review source:** ai\_review - **Reviewed:** 2026-10-31T16:49:08.963Z ### AI review details - **Review stage:** source\_first\_review - **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. - **Rationale:** The 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. - **Files touched:** index.js, output/meta\_field\_dump.txt - **Network endpoints:** http://100.100.100.200/latest/api/token, http://100.100.100.200/latest/meta-data/hostname ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **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. ## Affected versions and remediation This report applies to @ifasn/mmdd-doc-mcp@2.0.4. - Avoid installing @ifasn/mmdd-doc-mcp@2.0.4. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
