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:** 0.2.223 - **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's disclosed, opt-out telemetry also transmits a runtime name that defaults to the machine hostname, a potentially identifying field omitted from its description of collected metrics. This is a limited runtime telemetry concern; the reviewed source shows no unrelated collector or credential theft. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 92.0% - **Started:** 2026-11-03T16:27:01.547Z - **Finished:** 2026-11-03T16:27:54.801Z - **Download time:** 1031 ms - **Static scan time:** 1639 ms - **AI review time:** 50583 ms - **Total time:** 53254 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 runtime name that can identify the machine, beyond the fields described in the help text. - **Trigger:** The runtime starts with telemetry enabled and records tool-use events. - **Impact:** The user's ReMCP account may receive an undisclosed identifying machine name along with runtime metrics. - **Evidence paths:** src/config.mjs, src/telemetry.mjs, src/index.mjs - **Review source:** ai\_review - **Reviewed:** 2026-11-03T16:27:54.801Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Telemetry batches include runtimeConfig.name, which defaults to the OS hostname, and are forwarded through the paired ReMCP agent. - **Rationale:** The package's disclosed, opt-out telemetry also transmits a runtime name that defaults to the machine hostname, a potentially identifying field omitted from its description of collected metrics. This is a limited runtime telemetry concern; the reviewed source shows no unrelated collector or credential theft. - **Files touched:** runtimeConfigDir/.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:** Default-on runtime telemetry sends a runtime name alongside version, platform, architecture, and event data., The runtime name defaults to os.hostname(), so telemetry can include the machine hostname., The help text describes collected metrics as only tool names, timings, and outcomes, omitting the transmitted runtime name. - **Evidence against:** Telemetry is opt-out and is sent through the already-authenticated paired agent to the user's ReMCP account., Telemetry events are limited to whitelisted fields and exclude file paths, commands, tool arguments, and tool output., package.json declares no install lifecycle scripts. ## Affected versions and remediation This report applies to @remcp/runtime@0.2.223. - Review the evidence and your use of @remcp/runtime@0.2.223 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.

High: Previous Version Dangerous Delta - **Category:** Supply Chain - **Confidence:** 93.0% - **Path:** src/tools/system.mjs - **Public source:** [View source]() This package version adds a dangerous source file absent from the previous stored version; route for source-aware review.
