Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. The Markdown server automatically reads cloud instance identifiers at startup and writes successful responses into its working directory, an unnecessary behavior for its advertised tools. I found no evidence that it sends those values elsewhere, so this is a warning rather than a confirmed attack. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 95.0% - **Started:** 2026-10-29T05:34:11.970Z - **Finished:** 2026-10-29T05:34:36.768Z - **Download time:** 506 ms - **Static scan time:** 25 ms - **AI review time:** 24266 ms - **Total time:** 24798 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:** At startup, the MCP server probes cloud instance metadata and stores successful responses in a local file. - **Trigger:** Importing or starting \`index.js\`. - **Impact:** Cloud environment identifiers may be exposed to processes or users able to read the package’s working directory; no external transfer of the values was identified in the inspected source. - **Evidence paths:** index.js, output/meta\_field\_dump.txt - **Review source:** ai\_review - **Reviewed:** 2026-10-29T05:34:36.768Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** A startup call fetches several fields from \`http://100.100.100.200/latest/meta-data/\` and writes successful responses to \`output/meta\_field\_dump.txt\`. - **Rationale:** The Markdown server automatically reads cloud instance identifiers at startup and writes successful responses into its working directory, an unnecessary behavior for its advertised tools. I found no evidence that it sends those values elsewhere, so this is a warning rather than a confirmed attack. - **Files touched:** output/meta\_field\_dump.txt - **Network endpoints:** http://100.100.100.200/latest/meta-data/ ### Review decision - **Verdict:** Suspicious - **Confidence:** 95.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The package is described as a Markdown document toolkit, with \`index.js\` as its main entry point., At startup, the entry point automatically requests cloud metadata fields including hostname, instance ID and owner account ID., Successful metadata responses are written to \`output/meta\_field\_dump.txt\`., The metadata request uses GET; the inspected source does not send the collected values to another host. - **Evidence against:** The package’s advertised Markdown tools perform TOC generation, text statistics and table formatting., The inspected metadata flow has no apparent credential collection or outbound transfer of the response values. ## Affected versions and remediation This report applies to @ifasn/mmdd-doc-mcp@1.0.2. - Review the evidence and your use of @ifasn/mmdd-doc-mcp@1.0.2 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
