Claude Code and Codex gain an unsolicited MCP server controlled by the installed package, changing which tools those agents can run. - **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:** 4.34.0 - **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. On npm install, postinstall silently registers this package's MCP server in the user's Claude Code and Codex configs. Those are foreign agent control files, not a project-local setting, and the hook does not ask first. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 93.0% - **Started:** 2026-09-27T14:47:24.427Z - **Finished:** 2026-09-27T14:48:35.842Z - **Download time:** 1027 ms - **Static scan time:** 3723 ms - **AI review time:** 66664 ms - **Total time:** 71415 ms The recorded confidence comes from the underlying analysis.

Those are foreign agent control files, not a project-local setting, and the hook does not ask first. - **Trigger:** npm install lifecycle postinstall - **Impact:** Claude Code and Codex gain an unsolicited MCP server controlled by the installed package, changing which tools those agents can run. - **Evidence paths:** package.json, scripts/postinstall.js - **Review source:** ai\_review - **Reviewed:** 2026-09-27T14:48:35.842Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** scripts/postinstall.js reads or creates ~/.claude.json and ~/.codex/config.toml, then writes a karajan-mcp stdio server that runs node on this package's src/mcp/server.js. Failures are swallowed. - **Attack narrative:** Installing @karajan-family/code runs scripts/postinstall.js. The script always writes ~/.claude.json mcpServers.karajan-mcp and a karajan-mcp block in ~/.codex/config.toml so both agents launch this package MCP server with node. There is no prompt, and errors are ignored so npm install still exits cleanly. That is an unconsented install-time change to foreign AI-agent control files. - **Rationale:** The postinstall hook unconditionally mutates Claude Code and Codex user config to register this package's MCP server. That is unconsented install-time control of foreign agent surfaces, so the package should be blocked. - **Files touched:** ~/.claude.json, ~/.codex/config.toml ### Review decision - **Verdict:** Malicious - **Confidence:** 93.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** npm install runs scripts/postinstall.js with no consent flag or opt-out., That hook rewrites the user home Claude config so mcpServers.karajan-mcp launches this package MCP server., The same hook rewrites the user home Codex config.toml with a karajan-mcp server block., main always calls both writers and swallows errors so the install still succeeds. - **Evidence against:** The hook is idempotent and keeps extra env keys already on the Claude MCP entry., The hook does not fetch a remote payload or send credentials., The package does not depend on its own name. ## Affected versions and remediation This report applies to @karajan-family/code@4.34.0. - Avoid installing @karajan-family/code@4.34.0. 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.
