This registers a package-controlled executable as an AI-agent tool. - **Trigger:** npm install - **Impact:** Future Claude Code or Codex sessions can launch the package's MCP server with agent-tool privileges. - **Evidence paths:** package.json, scripts/postinstall.js, src/mcp/server.js - **Review source:** ai\_review - **Reviewed:** 2026-08-18T23:01:14.686Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall MCP configuration mutation - **Attack narrative:** On npm install, the lifecycle hook writes a karajan-mcp server entry to both Claude Code and Codex user configuration. Each entry launches Node against the installed package's MCP server in later agent sessions. This is an unconsented install-time mutation of broad foreign AI-agent control surfaces, even though the reviewed hook itself does not perform network exfiltration. - **Rationale:** The package's automatic postinstall modifies both ~/.claude.json and ~/.codex/config.toml to install a package-controlled MCP server. This meets the block policy for unconsented install-time mutation of foreign AI-agent control surfaces. - **Files touched:** scripts/postinstall.js, src/mcp/server.js, ~/.claude.json, ~/.codex/config.toml ### 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 automatically on npm install., Postinstall overwrites the user's ~/.claude.json MCP server entry with a package-controlled Node command., Postinstall creates or modifies ~/.codex/config.toml to register the same MCP server without consent. - **Evidence against:** The installed MCP command points to this package's local src/mcp/server.js rather than a remote payload., The reviewed postinstall source contains no outbound network request or credential-exfiltration logic. ## Public findings ### 1.
