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 has real persistent AI-agent control-surface behavior, including MCP registration, so it warrants a warning under the extension-lifecycle policy. The behavior is user-invoked and source inspection found no concrete malicious chain. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 90.0% - **Started:** 2026-08-15T11:19:58.567Z - **Finished:** 2026-08-15T11:21:20.051Z - **Download time:** 1015 ms - **Static scan time:** 1379 ms - **AI review time:** 79089 ms - **Total time:** 81484 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:** A user-invoked installer modifies AI-agent configuration and registers a global MCP server. No unconsented npm lifecycle execution or malicious payload chain was confirmed. - **Trigger:** Running multi-agent-pipeline install (or invoking the bin with no command). - **Impact:** Persistent behavior-bearing configuration in ~/.claude, ~/.copilot, and ~/.codex; MCP registration launches @mmerterden/dev-toolkit-mcp through npx when used. - **Evidence paths:** package.json, index.js, install/index.mjs, install/claude.mjs, install/codex.mjs, install/\_mcp-register.mjs, install/\_telemetry.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-15T11:21:20.051Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Copies agent assets, adds Claude hooks, and invokes host CLI MCP registration. - **Rationale:** The package has real persistent AI-agent control-surface behavior, including MCP registration, so it warrants a warning under the extension-lifecycle policy. The behavior is user-invoked and source inspection found no concrete malicious chain. - **Files touched:** ~/.claude/commands, ~/.claude/settings.json, ~/.copilot, ~/.codex/AGENTS.md, ~/.codex/config.toml - **Network endpoints:** https://mmerterden.vercel.app/api/install-notify ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for warning:** Explicit CLI install writes Claude/Copilot/Codex agent extensions., Installer adds Claude PreToolUse shell hooks., Installer registers an MCP server that runs another npm package via npx., Opt-in telemetry POSTs basic install metadata to mmerterden.vercel.app. - **Evidence against:** package.json has no preinstall, install, or postinstall lifecycle hook., Mutations occur only through the package CLI installer; dry-run and MCP-registration opt-out exist., No source evidence of credential harvesting, covert exfiltration, obfuscated payloads, or destructive install-time behavior. ## Affected versions and remediation This report applies to @mmerterden/multi-agent-pipeline@15.0.0. - Review the evidence and your use of @mmerterden/multi-agent-pipeline@15.0.0 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.
