Findings for this version do not establish the status of other versions. AI assessment: manual review; recommendation: manual review. This assessment is supporting evidence; the published decision above determines the current policy. Inspected install scripts set up this package's own daemon and app update rather than a proven foreign-agent or exfiltration attack, so a block or warning is not source-justified. Clean cannot be returned because the required citation coverage exceeds the eight-citation limit. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 62.0% - **Started:** 2026-09-27T22:27:46.095Z - **Finished:** 2026-09-27T22:29:15.677Z - **Download time:** 1015 ms - **Static scan time:** 3501 ms - **AI review time:** 85065 ms - **Total time:** 89582 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 confirmed attack was established. The npm postinstall path sets up this package's own launcher and LaunchAgent and can update its own desktop app from its GitHub releases. A clean decision cannot be published because the required citation list exceeds the citation limit. - **Trigger:** npm install runs the postinstall script; agent-home reads occur only if a user runs the related CLI or benchmark. - **Impact:** A normal install can start this package's own daemon. No secret theft, foreign agent hijack, or self-install chain was confirmed in the inspected files. - **Review source:** ai\_review - **Reviewed:** 2026-09-27T22:29:15.677Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Install scripts write ~/.trace launcher files and may bootstrap com.trace-mcp.server. Hinted agent paths are constants or explicit local-log benchmarks, not an install-time rewrite of foreign agent configs found in the inspected scripts. - **Rationale:** Inspected install scripts set up this package's own daemon and app update rather than a proven foreign-agent or exfiltration attack, so a block or warning is not source-justified. Clean cannot be returned because the required citation coverage exceeds the eight-citation limit. ### Review decision - **Verdict:** Manual Review - **Confidence:** 62.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** package.json postinstall runs local preflight, app-update, and control-plane scripts and does not depend on the trace-mcp package name., postinstall-control-plane bootstraps the package's own LaunchAgent com.trace-mcp.server and can be skipped with TRACE\_MCP\_NO\_POSTINSTALL or a dev checkout., The desktop zip source defaults to the same GitHub repo, nikolai-vysotskyi/trace-mcp., The hinted dist/proxy.js region only defines client home path constants such as .claude.json and .codex., scripts/state-trace-replay.ts reads local ~/.claude/projects logs only when that benchmark command is run., Required mark\_clean citation coverage is 16 paths while sourceCitations allows 8, so a clean verdict cannot be finalized from this pass. - **Evidence against:** The install hook still writes this package's launcher and LaunchAgent and can start its daemon without a separate consent prompt., Client settings mutation appears tied to explicit CLI init rather than the npm postinstall scripts inspected here. ## Affected versions and remediation This report applies to trace-mcp@3.26.3. - Review the evidence and your use of trace-mcp@3.26.3 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.
