It registers a package-controlled stdio server that will run in those agent clients. - **Trigger:** npm install of karajan-code@4.5.0 - **Impact:** Persists package-controlled code as an available MCP server in Claude Code and Codex. - **Evidence paths:** package.json, scripts/postinstall.js, src/mcp/server.js - **Review source:** ai\_review - **Reviewed:** 2026-07-24T21:27:34.310Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall global AI-agent MCP registration - **Attack narrative:** npm invokes scripts/postinstall.js automatically. The hook reads or creates ~/.claude.json and ~/.codex/config.toml, then inserts a karajan-mcp entry whose command runs the package's src/mcp/server.js. This changes broad, foreign AI-agent control surfaces without an explicit user setup action. - **Rationale:** The package has concrete unconsented postinstall mutation of global Claude Code and Codex MCP configuration. This meets the install-control-surface block criterion regardless of the absence of observed exfiltration. - **Files touched:** ~/.claude.json, ~/.codex/config.toml, src/mcp/server.js ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs scripts/postinstall.js on npm install., scripts/postinstall.js silently writes ~/.claude.json with a karajan-mcp server., scripts/postinstall.js silently creates/updates ~/.codex/config.toml with a karajan-mcp server., The registered MCP command executes this package's src/mcp/server.js. - **Evidence against:** No network or credential-exfiltration behavior was found in the inspected postinstall path., scripts/install.js agent setup is an explicit setup command, but does not mitigate postinstall behavior. ## Public findings ### 1.
