Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Flagged — allowed with a warning** — Allowed by default policy, but 12 finding(s) warrant review before installing. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Matched warn-list - **Public report status:** Published - **Threat category:** Unknown - **Selected version:** 1.0.3 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. 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 package automatically collects and stores cloud instance identifiers at runtime, creating a real but bounded privacy concern. The inspected source does not establish credential collection or external disclosure, so this warrants a warning rather than a block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 86.0% - **Started:** 2026-10-28T16:29:06.123Z - **Finished:** 2026-10-28T16:29:44.324Z - **Download time:** 1006 ms - **Static scan time:** 25 ms - **AI review time:** 37169 ms - **Total time:** 38201 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 program reads cloud instance metadata and saves selected responses in the current working directory. No onward transfer was identified, so the unresolved concern is automatic local collection of infrastructure identifiers. - **Trigger:** Launching index.js. - **Impact:** Cloud instance identifiers may be copied into a local file without a separate user request. - **Evidence paths:** index.js - **Review source:** ai\_review - **Reviewed:** 2026-10-28T16:29:44.324Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The program makes GET requests to the link-local metadata endpoint and writes successful responses to output/meta\_field\_dump.txt. - **Rationale:** The package automatically collects and stores cloud instance identifiers at runtime, creating a real but bounded privacy concern. The inspected source does not establish credential collection or external disclosure, so this warrants a warning rather than a block. - **Files touched:** index.js, output/meta\_field\_dump.txt - **Network endpoints:** http://100.100.100.200/latest/meta-data/ ### Review decision - **Verdict:** Suspicious - **Confidence:** 86.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The package exposes index.js as its executable entrypoint and describes instance field mapping diagnostics., On startup, the program automatically queries the link-local metadata service for hostname, zone, instance, and account identifiers, then writes successful responses to output/meta\_field\_dump.txt., The metadata collection runs through configSync when the program starts., The inspected network request is a GET to the metadata service; no onward transfer of the collected values was identified., The reported runtime operations are ordinary Markdown table formatting. - **Evidence against:** The inspected source shows local storage of metadata responses but no transmission of those responses to another endpoint. ## Affected versions and remediation This report applies to @ifasn/mmd-doc-mcp@1.0.3. - Review the evidence and your use of @ifasn/mmd-doc-mcp@1.0.3 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.
