AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The package automatically probes cloud instance metadata, including the RAM role listing, despite being a Markdown utility. Its entry point also sends probe statuses to a hard-coded external beacon, so this is malicious behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-10-31T16:48:26.836Z - **Finished:** 2026-10-31T16:48:58.918Z - **Download time:** 760 ms - **Static scan time:** 163 ms - **AI review time:** 31158 ms - **Total time:** 32082 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:** The Markdown MCP entry point automatically probes cloud instance metadata and reports probe statuses externally. - **Trigger:** Unconditional call to v2Probe() when index.js starts. - **Impact:** Unrequested collection of cloud instance metadata and disclosure of probe results to an unrelated host. - **Evidence paths:** index.js - **Review source:** ai\_review - **Reviewed:** 2026-10-31T16:48:58.918Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Requests an Aliyun metadata token, reads metadata including the RAM role listing, saves probe output locally, and sends result statuses to a hard-coded beacon. - **Attack narrative:** When the package entry point starts, it requests an Aliyun instance metadata v2 token and uses it to query metadata, including the RAM security-credentials role listing. It saves probe results locally and sends status information to a hard-coded external beacon. This automatic cloud metadata collection is unrelated to the package’s Markdown tools. - **Rationale:** The package automatically probes cloud instance metadata, including the RAM role listing, despite being a Markdown utility. Its entry point also sends probe statuses to a hard-coded external beacon, so this is malicious behavior. - **Files touched:** output/meta\_field\_dump.txt - **Network endpoints:** 100.100.100.200, 121.199.24.94.nip.io, 121.199.24.94 ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The entry point requests an Aliyun instance metadata v2 token from 100.100.100.200., With the token, it reads the instance metadata RAM security-credentials role listing., The metadata probe runs unconditionally when index.js starts., The probe sends its result statuses to a hard-coded external beacon and writes probe output to output/meta\_field\_dump.txt. - **Evidence against:** The package describes Markdown table-of-contents, statistics, and table-formatting tools., package.json has no install lifecycle script. ## Affected versions and remediation This report applies to @ifasn/mmdd-doc-mcp@2.0.1. - Avoid installing @ifasn/mmdd-doc-mcp@2.0.1. 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.
