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’s disclosed, opt-out telemetry sends tool usage through the paired ReMCP agent, but its payload also includes a runtime name that defaults to the machine hostname. That identifying detail makes the runtime telemetry suspicious. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-11-01T23:18:29.132Z - **Finished:** 2026-11-01T23:19:09.787Z - **Download time:** 510 ms - **Static scan time:** 1591 ms - **AI review time:** 38553 ms - **Total time:** 40655 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-on runtime telemetry includes a name that defaults to the machine hostname. - **Trigger:** The runtime starts with telemetry enabled; events are buffered and sent periodically or during shutdown. - **Impact:** The hostname can identify the machine alongside its tool usage. The package discloses telemetry and offers an opt-out, but the identifying detail makes this telemetry suspicious under the review rules. - **Evidence paths:** src/config.mjs, src/telemetry.mjs, src/index.mjs - **Review source:** ai\_review - **Reviewed:** 2026-11-01T23:19:09.787Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Telemetry is sent as an MCP notification to the paired ReMCP agent, and its payload includes runtimeConfig.name, which defaults to os.hostname(). - **Rationale:** The package’s disclosed, opt-out telemetry sends tool usage through the paired ReMCP agent, but its payload also includes a runtime name that defaults to the machine hostname. That identifying detail makes the runtime telemetry suspicious. - **Files touched:** src/config.mjs, src/telemetry.mjs, src/index.mjs ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Medium - **Evidence for warning:** Runtime telemetry is enabled by default and can be disabled through configuration., Telemetry includes a runtime name that defaults to the machine hostname, alongside tool usage data., The runtime sends telemetry notifications to the paired ReMCP agent; no destination host is specified in this package. - **Evidence against:** The package describes its telemetry and provides an opt-out., Telemetry events are limited to tool names, timings, outcomes and coarse error classes; they exclude paths, commands, arguments and tool output., The manifest has no lifecycle hooks, and the screenshot portal loads its D-Bus dependency only when capture is requested. ## Affected versions and remediation This report applies to @remcp/runtime@0.2.203. - Review the evidence and your use of @remcp/runtime@0.2.203 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.
