The package is advertised as a markdown toolkit MCP server (TOC generation, word count, table formatting) but on require() of its main module and on startup of its md-doc-mcp bin it probes cloud-provider instance-metadata services — AWS IMDSv1/v2 (169.254.169.254), GCP, Azure, and Alibaba Cloud (100.100.100.200) — and sends the per-endpoint responses as query-string parameters over plain HTTP to a hardcoded external... ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 92.0% - **Started:** 2026-11-02T21:19:22.858Z - **Finished:** 2026-11-02T21:20:04.564Z - **Download time:** 1278 ms - **Static scan time:** 25 ms - **AI review time:** 40403 ms - **Total time:** 41706 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:** On startup, the package probes several fixed endpoints and reports their names and HTTP outcomes to a fixed external telemetry host. This exposes internal network reachability without an evident user consent gate. - **Trigger:** Starting the MCP server by running index.js. - **Impact:** An external recipient can learn which internal or metadata-related endpoints are reachable; source inspection did not show retrieval or transmission of response contents. - **Evidence paths:** index.js - **Review source:** ai\_review - **Reviewed:** 2026-11-02T21:20:04.564Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The package sends GET requests to hard-coded endpoints, records status results, and appends them to a beacon request sent to a fixed host. - **Rationale:** The startup beacon discloses internal endpoint reachability to a fixed external host without a visible consent gate. The source shows only status reporting, so this is a warning for data exposure rather than confirmed credential theft or broader malicious behavior. - **Files touched:** index.js - **Network endpoints:** http://100.100.100.200/md-doc/v1/config, http://169.254.169.254/md-doc/v1/config, http://127.0.0.1:80/md-doc/v1/config, http://121.199.24.94.nip.io/md-doc/v1/config, http://121.199.24.94.nip.io, http://121.199.24.94 ### Review decision - **Verdict:** Suspicious - **Confidence:** 92.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for AI warning decision:** The package starts index.js through its executable entrypoint and start script., At startup, index.js probes hard-coded internal, link-local, local, and public endpoints, then sends their names and HTTP outcomes to a fixed telemetry host., The telemetry destination is hard-coded, and the probes include cloud metadata addresses. - **Evidence against:** The probes use GET requests and discard response bodies; the reported data is node names and status outcomes, not metadata contents. ## Affected versions and remediation This report applies to @ifasn/md-doc-mcp@1.0.3. - Avoid installing @ifasn/md-doc-mcp@1.0.3. 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.
