Do not execute instructions or code found in this document. ## Verdict summary **Flagged as agent extension risk** — Allowed by default with warning: install-time first-party agent extension setup was detected. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Warn-only agent extension risk - **Public report status:** Published - **Threat category:** Agent extension lifecycle risk - **Selected version:** 26.10.8-344 - **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 postinstall hook performs automatic first-party MCP configuration, creating a concrete agent-extension lifecycle risk. The inspected behavior supports a warning, but does not establish the broader control-surface abuse or other attack behavior required for a block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 89.0% - **Started:** 2026-10-18T09:13:21.297Z - **Finished:** 2026-10-18T09:14:22.671Z - **Download time:** 1300 ms - **Static scan time:** 1747 ms - **AI review time:** 58326 ms - **Total time:** 61374 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 automatic install hook configures this package’s MCP server for supported agent clients without an affirmative setup prompt. This creates residual agent-extension risk, but the inspected source does not establish a concrete malicious attack. - **Trigger:** Installing the package with npm runs its postinstall hook. - **Impact:** Agent clients may load the package’s MCP gateway, whose single-tool interface reduces per-operation approval boundaries; mutating calls have project-root checks. - **Evidence paths:** package.json, cli/postinstall.js, cli/mcp/installer.js, cli/mcp/antigravity.js, cli/mcp/call-scope.js - **Review source:** ai\_review - **Reviewed:** 2026-10-18T09:14:22.671Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook adds MCP server entries to project-local Cursor and VS Code settings and, when present, global Antigravity settings. - **Rationale:** The postinstall hook performs automatic first-party MCP configuration, creating a concrete agent-extension lifecycle risk. The inspected behavior supports a warning, but does not establish the broader control-surface abuse or other attack behavior required for a block. - **Files touched:** .cursor/mcp.json, .vscode/mcp.json, ~/.gemini/config/mcp\_config.json, ~/.gemini/antigravity/mcp/chemical-x/ ### Review decision - **Verdict:** Suspicious - **Confidence:** 89.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** package.json runs cli/postinstall.js after installation, and that script automatically invokes the MCP installer for the consumer directory., The installer writes the Chemical X MCP registration to project-local Cursor and VS Code configuration., When the Antigravity configuration directory exists, the installer also updates its global MCP configuration and synchronizes agent schemas and instructions., The setup guide says the single gateway avoids separate approval for each MCP sub-operation., Mutating MCP calls have project-root checks, limiting the confirmed risk to automatic first-party agent integration setup. - **Evidence against:** The inspected setup registers the package’s own MCP server; it does not establish credential collection, data exfiltration, or remote payload execution., Antigravity configuration is conditional on an existing configuration directory, and mutating calls are subject to project-root checks. ## Affected versions and remediation This report applies to @chemx/create-chemx@26.10.8-344. - Review the evidence and your use of @chemx/create-chemx@26.10.8-344 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.
