It adds hooks and MCP server entries that can affect future agent sessions. - **Trigger:** Running npm install -g devcodex activates postinstall. - **Impact:** It broadens control of multiple independent AI-agent runtimes without a separate setup command. - **Evidence paths:** package.json, scripts/postinstall.js, scripts/lib/npm-lifecycle-adapter.js, scripts/lib/global-host-target.js, scripts/lib/global-host-config.js - **Review source:** ai\_review - **Reviewed:** 2026-09-07T19:30:24.233Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall writes global AI-agent hooks, instructions, and MCP configuration. - **Attack narrative:** Installing this package globally triggers postinstall. The lifecycle adapter invokes the global configuration routine, which resolves six AI-agent home directories and writes hooks, instructions, and MCP configuration. The Codex configuration includes approved MCP tools. This is an automatic, broad mutation of foreign agent control surfaces, not an explicit follow-up setup action. - **Rationale:** The package uses an automatic npm lifecycle hook to modify global configuration for multiple unrelated AI-agent products and to register executable MCP integrations. This meets the install-hook abuse policy even though no credential theft or network exfiltration was found. - **Files touched:** package.json, scripts/postinstall.js, scripts/lib/npm-lifecycle-adapter.js, scripts/lib/global-host-target.js, scripts/lib/global-host-config.js ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The manifest automatically runs a postinstall script., On global installation, the lifecycle code executes global host configuration rather than only reporting guidance., The configuration targets six unrelated AI-agent user homes, including Codex, Claude, Copilot, Gemini, Grok, and Cursor., It installs global hooks and MCP servers, and marks Codex MCP tools as approved. - **Evidence against:** No runtime dependency on devcodex itself is declared., The inspected install path contains no network request or credential-exfiltration code. ## Affected versions and remediation This report applies to devcodex@1.20.1. - Avoid installing devcodex@1.20.1. 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.
