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 explicit agent configuration setup is a guarded, package-owned capability and merits a warning. No concrete malicious install behavior was established, and the declared postinstall file was absent from the inspected package snapshot. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-12T06:02:53.539Z - **Finished:** 2026-10-12T06:03:26.351Z - **Download time:** 510 ms - **Static scan time:** 800 ms - **AI review time:** 31501 ms - **Total time:** 32812 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:** The explicit installer can change project AI-agent configuration by appending a search directive to AGENTS.md and registering a Chemical X MCP server. - **Trigger:** A user selects an installer option or runs the MCP installation command. - **Impact:** This changes later agent guidance and enables the configured package MCP server; no install-time attack was established. - **Evidence paths:** cli/installer.js, cli/mcp/installer.js, cli/mcp/index.js - **Review source:** ai\_review - **Reviewed:** 2026-10-12T06:03:26.351Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The installer writes package scripts and agent-facing configuration into the selected project. - **Rationale:** The explicit agent configuration setup is a guarded, package-owned capability and merits a warning. No concrete malicious install behavior was established, and the declared postinstall file was absent from the inspected package snapshot. - **Files touched:** AGENTS.md, .cursor/mcp.json ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The interactive installer offers optional MCP configuration and an agent query setup that adds a search directive to AGENTS.md., The MCP installer writes a Chemical X server entry into project Cursor configuration; the explicit MCP command invokes that installer., The manifest declares a postinstall command whose referenced scripts/postinstall.mjs file is absent from this package snapshot. - **Evidence against:** Agent and MCP configuration changes are exposed through interactive installer choices or an explicit MCP command, not proven to run during package installation., The manifest ships the cli directory, while the declared postinstall script file is absent; no postinstall mutation behavior was found. ## Affected versions and remediation This report applies to @chem-x/create-chemx@26.9.16-668. - Review the evidence and your use of @chem-x/create-chemx@26.9.16-668 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.
