A dependency installation changes the consumer project's AI-agent control surface and enables package-controlled local commands; it also modifies the installed three dependency. - **Verdict:** AI-agent control-surface policy finding - **Product-default install policy:** Warn by default; block when configured - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 0.3.2 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This finding concerns changes to an AI agent's instructions or configuration without explicit user action. It does not by itself establish malware intent. The CLI warns by default and blocks when configured for this policy. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. LPM flags this version as an AI-agent control-surface risk. Installing the package automatically modifies several third-party AI-agent project configuration files. It registers commands that launch package MCP servers and may fetch missing server packages through npx. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-12T08:18:46.876Z - **Finished:** 2026-09-12T08:20:02.667Z - **Download time:** 771 ms - **Static scan time:** 1918 ms - **AI review time:** 73101 ms - **Total time:** 75791 ms The recorded confidence comes from the underlying analysis.

It registers commands that launch package MCP servers and may fetch missing server packages through npx. - **Trigger:** npm install runs the postinstall lifecycle hook. - **Impact:** A dependency installation changes the consumer project's AI-agent control surface and enables package-controlled local commands; it also modifies the installed three dependency. - **Evidence paths:** package.json, scripts/postinstall.mjs, scripts/ensure-mcp.mjs, mcp/install.mjs, mcp/servers.mjs, mcp/launch.mjs, scripts/apply-three-patch.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-12T08:20:02.667Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic multi-host MCP configuration writes and command registration. - **Attack narrative:** On installation, the postinstall hook patches the consumer's three package and invokes MCP setup. Setup automatically creates or changes project configuration for Claude Code, Codex, Cursor, VS Code, Gemini CLI, opencode, and Zed. The added entries execute Node programs from this dependency when an agent host activates them. Those programs dynamically import resolved MCP packages and can invoke npx to retrieve a missing package. The opt-out is only an environment variable supplied before installation, so ordinary dependency installation mutates a broad, foreign AI-agent control surface without an explicit setup command. - **Rationale:** This is concrete unconsented postinstall mutation of multiple foreign AI-agent configuration surfaces, coupled to package-controlled command execution and dependency patching. Safeguards and an opt-out do not remove that automatic control-surface change. - **Files touched:** .mcp.json, .codex/config.toml, .cursor/mcp.json, .vscode/mcp.json, .gemini/settings.json, opencode.json, .zed/settings.json, node\_modules/three ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The automatic postinstall runs MCP setup without an explicit user command., The installer creates or updates configuration for seven unrelated AI-agent hosts., Those configurations register Node commands that run this package's MCP entry points., MCP launchers dynamically import resolved packages and fall back to npx network installation., The same postinstall also patches the consumer's installed three dependency. - **Evidence against:** The configuration targeting code skips nested installs and requires the consuming manifest to declare this package., It offers an environment-variable opt-out and avoids machine-wide config paths., No credential harvesting or direct secret exfiltration was found in inspected sources. ## Affected versions and remediation This report applies to @threenative/core@0.3.2. - Avoid installing @threenative/core@0.3.2. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
