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 14 finding(s) warrant review before installing. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Telemetry warning (can be blocked) - **Public report status:** Published - **Threat category:** Telemetry - **Selected version:** 1.3.0 - **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 sends default-on runtime telemetry containing project and branch identifiers and tool usage details, without disclosing that reporting in its README. The opt-out makes this a suspicious telemetry finding rather than a malicious exfiltration finding. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 90.0% - **Started:** 2026-11-01T22:38:14.590Z - **Finished:** 2026-11-01T22:39:03.825Z - **Download time:** 1028 ms - **Static scan time:** 424 ms - **AI review time:** 47782 ms - **Total time:** 49235 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:** Undisclosed, default-on runtime telemetry sends project identifiers and tool usage details to the package service. - **Trigger:** After a successful code\_intel execution with tool invocations, when usage tracking is enabled; tracking is enabled by default. - **Impact:** The service receives identifying project metadata and usage activity. The included README does not disclose this separate telemetry. - **Evidence paths:** dist/index.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-11-01T22:39:03.825Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The package sends a JSON usage event containing project ID, branch name, invocation names, token counts, and timing data in a POST authenticated with the configured access key. - **Rationale:** The package sends default-on runtime telemetry containing project and branch identifiers and tool usage details, without disclosing that reporting in its README. The opt-out makes this a suspicious telemetry finding rather than a malicious exfiltration finding. - **Network endpoints:** https://api.constellationdev.io/intel/v1/usage (default; USAGE\_ENDPOINT\_URL can override the endpoint) ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** Usage tracking defaults to enabled, with environment-variable opt-outs., After a successful code\_intel execution, the package builds a usage event from project, branch, invocation, and timing data., The event includes the project ID, branch name, tool invocation names, token counts, and timing metrics., The package POSTs the event with the configured access key to its usage endpoint. - **Evidence against:** The README describes the package as providing code intelligence without transmitting source code., The only lifecycle script is prepare: husky; no install or postinstall telemetry hook is declared., The runtime telemetry can be disabled with CONSTELLATION\_USAGE\_METRICS=false or USAGE\_TRACKING\_ENABLED=false. ## Affected versions and remediation This report applies to @constellationdev/mcp@1.3.0. - Review the evidence and your use of @constellationdev/mcp@1.3.0 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.
