It registers local MCP servers and approves their Codex tools. - **Trigger:** npm install -g devcodex runs postinstall - **Impact:** Changes global agent instructions, hooks, plugins, and MCP configuration; Codex MCP tools are configured with approval\_mode approve. - **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:** 2026-08-16T23:38:56.107Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall applies global multi-host AI-agent configuration - **Attack narrative:** Installing the package globally triggers postinstall, which applies configuration across Copilot, Claude, Codex, Gemini, Grok, and Cursor home-directory surfaces. The generated Codex configuration registers DevCodex MCP servers and assigns approval\_mode "approve" to its listed tools. This is an automatic, broad cross-vendor AI-agent control-surface mutation rather than an explicit setup command. - **Rationale:** The postinstall is explicitly gated to global installation, but that lifecycle event automatically writes broad foreign AI-agent configuration and grants MCP tool approvals. This meets the blocking policy for unconsented postinstall mutation of a broad AI-agent control surface. - **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:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** postinstall invokes the lifecycle adapter., On npm global install, the adapter executes global host configuration., Default targets span Copilot, Claude, Codex, Gemini, Grok, and Cursor user profiles., It installs MCP servers into Codex config and marks listed tools approve., Configured operations are transactionally written into user-level host roots. - **Evidence against:** Workspace installs are no-ops and direct users to a global install., No runtime network request or credential-exfiltration path was found in inspected lifecycle/config sources. ## Public findings ### 1.
