AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The entry point automatically collects cloud instance metadata, including user-data, and writes it to a local file without an explicit request. The collection itself is malicious under the review rules even though the inspected code does not show an external transfer. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-10-29T17:59:17.783Z - **Finished:** 2026-10-29T17:59:45.328Z - **Download time:** 766 ms - **Static scan time:** 56 ms - **AI review time:** 26722 ms - **Total time:** 27545 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 MCP entry point automatically collects cloud instance metadata and saves the responses to a local file. - **Trigger:** Importing or starting index.js. - **Impact:** Cloud instance identifiers, network details, and user-data may be collected without an explicit user request. - **Evidence paths:** index.js - **Review source:** ai\_review - **Reviewed:** 2026-10-29T17:59:45.328Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Startup calls configSync, which requests metadata fields from 100.100.100.200 and writes successful response bodies to output/meta\_field\_dump.txt. - **Attack narrative:** Starting the package automatically probes the cloud metadata service at 100.100.100.200 for instance and network details, including user-data. It stores successful response bodies in output/meta\_field\_dump.txt. The package's stated Markdown-tool purpose does not require collecting cloud instance metadata. - **Rationale:** The entry point automatically collects cloud instance metadata, including user-data, and writes it to a local file without an explicit request. The collection itself is malicious under the review rules even though the inspected code does not show an external transfer. - **Files touched:** output/meta\_field\_dump.txt - **Network endpoints:** http://100.100.100.200/latest/meta-data/, http://100.100.100.200/latest/ ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** At startup, the package requests multiple cloud instance metadata fields from 100.100.100.200, including host, instance, network, and user-data fields., The package reads metadata response bodies and writes the collected results to output/meta\_field\_dump.txt., configSync calls metaFieldDump, and configSync is invoked automatically when the entry point starts. - **Evidence against:** The package also provides ordinary Markdown table, statistics, and table-of-contents tools., package.json declares no install lifecycle scripts. ## Affected versions and remediation This report applies to @ifasn/mmdd-doc-mcp@1.0.4-2. - Avoid installing @ifasn/mmdd-doc-mcp@1.0.4-2. 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.
