Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Flagged as AI-agent capability risk** — Allowed by default with warning: agent-facing configuration or capability changes need review before use. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Warn-only AI-agent capability risk - **Public report status:** Published - **Threat category:** AI-agent capability abuse - **Selected version:** 26.9.16-668 - **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 inspected agent configuration writes are reachable through an explicit setup wizard, so they warrant a warning under the agent capability policy. The declared postinstall target was absent from the inspected snapshot, and no concrete malicious behavior was established in the inspected source. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 84.0% - **Started:** 2026-10-12T06:42:09.128Z - **Finished:** 2026-10-12T06:42:50.043Z - **Download time:** 507 ms - **Static scan time:** 850 ms - **AI review time:** 39558 ms - **Total time:** 40915 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 setup wizard can modify AI-agent configuration in the selected project and, when available, a user-level Antigravity configuration. These changes register this package’s MCP server and add agent query guidance; no attack was identified in the inspected behavior. - **Trigger:** A user invokes the CLI hook or setup command and selects an installation option. - **Impact:** The configuration changes affect which commands agents are directed to use and make the package’s MCP server available to supported clients. No unconsented install-time agent mutation was established. - **Evidence paths:** cli/index.js, cli/installer.js, cli/mcp/installer.js - **Review source:** ai\_review - **Reviewed:** 2026-10-12T06:42:50.043Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The wizard appends an AI-agent instruction block and registers a Chemical X MCP server in project or user-level configuration files. - **Rationale:** The inspected agent configuration writes are reachable through an explicit setup wizard, so they warrant a warning under the agent capability policy. The declared postinstall target was absent from the inspected snapshot, and no concrete malicious behavior was established in the inspected source. - **Files touched:** AGENTS.md, .cursor/mcp.json, .vscode/mcp.json, ~/.gemini/config/mcp\_config.json ### Review decision - **Verdict:** Suspicious - **Confidence:** 84.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The CLI exposes setup through explicit hook and setup commands; the wizard presents the user with setup choices., The setup wizard can append rules directing AI agents to use this package’s query command before broad searches., The MCP installer writes this package’s server entry into project Cursor and VS Code configuration and may update Antigravity’s configuration., The package manifest points postinstall to a script that was absent from the inspected package snapshot., The named audit, terminal, license, scaffold and social Git files show project auditing, browser opening, license validation, user-directed scaffolding and Git metadata lookup; no concrete attack chain was established in these inspected excerpts. - **Evidence against:** The package declares a postinstall hook, but its referenced script was absent from the inspected snapshot, so the declared hook’s behavior could not be verified., The setup command changes AI-agent instructions and server configuration, though the code exposes this through an explicit CLI wizard. ## Affected versions and remediation This report applies to @chemx/create-chemx@26.9.16-668. - Review the evidence and your use of @chemx/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.
