Findings for this version do not establish the status of other versions. AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. The flagged dependency bridge lazily loads the declared D-Bus package for a local screenshot tool. Runtime metrics are disclosed, opt-out, limited to usage fields, and routed through the user's paired agent. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 95.0% - **Started:** 2026-11-04T03:14:10.387Z - **Finished:** 2026-11-04T03:15:06.572Z - **Download time:** 509 ms - **Static scan time:** 1648 ms - **AI review time:** 54027 ms - **Total time:** 56185 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:** No attack was identified. The package provides a local MCP runtime with disclosed, opt-out usage metrics and user-invoked device tools. - **Trigger:** The runtime starts when launched; screenshot capture runs when its tool is called. - **Impact:** No unauthorized collection, account action, or unrelated network contact was identified. - **Review source:** ai\_review - **Reviewed:** 2026-11-04T03:15:06.572Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Metrics are sent through the authenticated paired agent using a restricted event-field allowlist. Screenshot capture uses local operating-system tools or the Linux desktop portal. - **Rationale:** The flagged dependency bridge lazily loads the declared D-Bus package for a local screenshot tool. Runtime metrics are disclosed, opt-out, limited to usage fields, and routed through the user's paired agent. - **Files touched:** os.tmpdir()/remcp-screenshot-\*, The screenshot directory supplied to the tool caller ### Review decision - **Verdict:** Clean - **Confidence:** 95.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The package declares start, check and test scripts, with no install lifecycle script., Runtime help discloses usage metrics, says they go through the paired ReMCP agent, and documents opt-out controls., Telemetry fields are limited to tool names, timings, outcomes and coarse error classes; tool arguments and output are excluded., Screenshots are captured when the screenshot tool is called, using local capture backends and the declared D-Bus dependency. ## Affected versions and remediation This report applies to @remcp/runtime@0.2.228. - Review the evidence and your use of @remcp/runtime@0.2.228 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.
