Project agent tools may launch this package's MCP server based on the modified configuration. - **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:** 0.1.5 - **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. The manifest activates a postinstall hook that modifies the consumer project's MCP configuration without affirmative consent, registering a command that launches this package. This is unconsented install-time mutation of an AI-agent control surface. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 97.0% - **Started:** 2026-10-17T02:48:51.327Z - **Finished:** 2026-10-17T02:49:31.837Z - **Download time:** 1007 ms - **Static scan time:** 5720 ms - **AI review time:** 33782 ms - **Total time:** 40510 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 install hook automatically adds a uidx MCP server to a local project's agent configuration. This enables the package's MCP command for tools that use that project configuration. - **Trigger:** Installing the package locally with npm in a project containing package.json. - **Impact:** Project agent tools may launch this package's MCP server based on the modified configuration. - **Evidence paths:** package.json, scripts/postinstall.mjs, dist/chunk-KDHYTQEB.js - **Review source:** ai\_review - **Reviewed:** 2026-10-17T02:49:31.837Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall calls initProject, which adds a uidx command entry to the project-root .mcp.json and writes the updated configuration without a consent prompt. - **Attack narrative:** A local npm install triggers postinstall, which runs project initialization. That initializer adds a uidx MCP server command to the project's .mcp.json without prompting, creating an agent control surface automatically. - **Rationale:** The manifest activates a postinstall hook that modifies the consumer project's MCP configuration without affirmative consent, registering a command that launches this package. This is unconsented install-time mutation of an AI-agent control surface. - **Files touched:** .mcp.json, package.json, scripts/postinstall.mjs, dist/chunk-KDHYTQEB.js ### Review decision - **Verdict:** Malicious - **Confidence:** 97.0% - **Recommended action:** publish\_block - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for policy risk:** The manifest runs scripts/postinstall.mjs during installation., The postinstall hook calls initProject for the containing local project without a consent prompt., Setup reads or creates the project-root .mcp.json file., Setup adds a uidx MCP server that runs the package's uidx:mcp script, then writes the configuration., The install hook also installs first-party skills into project agent directories. ## Affected versions and remediation This report applies to @uidxkit/uidx@0.1.5. - Avoid installing @uidxkit/uidx@0.1.5. 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.
