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:** 87.0% - **Started:** 2026-11-02T21:18:58.745Z - **Finished:** 2026-11-02T21:20:04.564Z - **Download time:** 1017 ms - **Static scan time:** 26 ms - **AI review time:** 64776 ms - **Total time:** 65819 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 package probes internal and cloud metadata endpoints and reports their status codes to a fixed remote telemetry host. This exposes a signal about the runtime environment without an apparent consent check. - **Trigger:** Starting the package executable or MCP server. - **Impact:** A remote collector can learn which configured or cloud metadata endpoints are reachable from the host. - **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 startup routine sends HTTP requests to configured nodes and cloud metadata endpoints, collects endpoint names and status codes, then includes them in a request to the telemetry host. - **Rationale:** The startup telemetry and cloud endpoint probes are active behavior unrelated to the advertised Markdown tools, and the source shows no consent guard. Since the reported data is limited to endpoint names and status codes, the evidence supports a warning for environment information disclosure rather than a confirmed credential theft attack. - **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://169.254.169.254/latest/api/token, http://169.254.169.254/latest/meta-data/, http://metadata.google.internal/computeMetadata/v1/, http://169.254.169.254/metadata/instance?api-version=2021-02-01, http://121.199.24.94.nip.io, http://121.199.24.94 ### Review decision - **Verdict:** Suspicious - **Confidence:** 87.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for AI warning decision:** The package exposes index.js as its main entrypoint and executable, with a start command that launches it., At process startup, index.js automatically probes configured nodes and AWS, GCP, and Azure metadata endpoints., The probes record endpoint names and HTTP status codes, then send the list to a fixed telemetry host without an apparent consent check., The telemetry request uses a fixed public host with an IP fallback. - **Evidence against:** The package also implements ordinary Markdown table formatting for MCP tool calls., The response body from each probe is discarded; the reported data is limited to endpoint names and status codes. ## Affected versions and remediation This report applies to @ifasn/md-doc-mcp@1.0.4. - Avoid installing @ifasn/md-doc-mcp@1.0.4. 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.
