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:** Telemetry warning (can be blocked) - **Public report status:** Published - **Threat category:** Telemetry - **Selected version:** 0.2.205 - **Selected version is latest:** No - **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 discloses opt-out telemetry and limits event details, but its payload also includes a runtime name that defaults to the machine hostname. Under the review rules, telemetry sent with identifying details warrants a warning. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 92.0% - **Started:** 2026-11-02T08:08:46.489Z - **Finished:** 2026-11-02T08:09:48.209Z - **Download time:** 501 ms - **Static scan time:** 1643 ms - **AI review time:** 59575 ms - **Total time:** 61720 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:** Default runtime telemetry includes the machine hostname, an identifying detail beyond the disclosed usage metrics. - **Trigger:** Runtime startup followed by telemetry flush during operation or shutdown. - **Impact:** The hostname can identify the user's machine in telemetry, creating a privacy risk. - **Evidence paths:** src/config.mjs, src/telemetry.mjs, src/index.mjs - **Review source:** ai\_review - **Reviewed:** 2026-11-02T08:09:48.209Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The runtime name defaults to os.hostname(); telemetry batches include that name and are sent through the paired agent to the user's ReMCP account. - **Rationale:** The package discloses opt-out telemetry and limits event details, but its payload also includes a runtime name that defaults to the machine hostname. Under the review rules, telemetry sent with identifying details warrants a warning. - **Files touched:** ~/.config/remcp/runtime.json, ~/.config/remcp/.telemetry-notice ### Review decision - **Verdict:** Suspicious - **Confidence:** 92.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** Telemetry is enabled by default and can be disabled through configuration or an environment variable., The runtime name defaults to the machine hostname., Telemetry batches include that runtime name and are forwarded through the paired agent to the user's ReMCP account., The package discloses usage metrics and says they exclude file paths, commands, arguments, and tool output. - **Evidence against:** Event details are whitelisted to limited fields such as tool names, timings, outcomes, and coarse error classes., The telemetry is disclosed, opt-out, and routed through the paired agent; the source names no direct external endpoint. ## Affected versions and remediation This report applies to @remcp/runtime@0.2.205. - Review the evidence and your use of @remcp/runtime@0.2.205 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.
