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:** Telemetry warning (can be blocked) - **Public report status:** Published - **Threat category:** Telemetry - **Selected version:** 0.2.206 - **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 runtime telemetry and allows users to disable it, but the payload includes a machine hostname by default. That identifying detail makes the telemetry suspicious under the review rules. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-11-02T09:58:03.075Z - **Finished:** 2026-11-02T09:58:43.150Z - **Download time:** 513 ms - **Static scan time:** 1607 ms - **AI review time:** 37953 ms - **Total time:** 40075 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 sends the machine hostname with usage metrics to the user's ReMCP account. - **Trigger:** Runtime startup enables telemetry by default; recorded events are sent when the buffer flushes. - **Impact:** The receiving ReMCP account can associate usage metrics with the machine's hostname. - **Evidence paths:** src/config.mjs, src/telemetry.mjs, src/index.mjs - **Review source:** ai\_review - **Reviewed:** 2026-11-02T09:58:43.150Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The payload includes runtimeConfig.name, which falls back to os.hostname(), and is sent through the paired agent. - **Rationale:** The package discloses runtime telemetry and allows users to disable it, but the payload includes a machine hostname by default. That identifying detail makes the telemetry suspicious under the review rules. ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Medium - **Evidence for warning:** Telemetry is enabled by default unless disabled by configuration., The telemetry payload includes runtimeConfig.name, which defaults to os.hostname()., The runtime says these metrics go to the user's ReMCP account through the paired agent. - **Evidence against:** Telemetry events use a whitelist that excludes file paths, commands, arguments, and tool output., The runtime discloses telemetry and provides settings to disable it., The reviewed screenshot and D-Bus behavior is tied to screenshot functionality rather than an unrelated data collection flow. ## Affected versions and remediation This report applies to @remcp/runtime@0.2.206. - Review the evidence and your use of @remcp/runtime@0.2.206 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.

Medium: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 91.0% - **Path:** src/config.mjs - **Public source:** [View source]() Telemetry is enabled by default unless disabled by configuration. Public source snippet (untrusted): ```javascript // Telemetry is opt-out, matching the ReMCP client: it is on unless the user (or the // ReMCP agent that spawned this runtime) turns it off. It never sends file paths, // command strings, arguments, or tool output - only tool names, timings and outcomes. const telemetryDisabled = booleanValue(process.env.REMCP_RUNTIME_DISABLE_TELEMETRY, f ``` ### 12. Medium: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 91.0% - **Path:** src/telemetry.mjs - **Public source:** [View source]() The telemetry payload includes runtimeConfig.name, which defaults to os.hostname().
