## Security analysis

### Published attack-surface review

- **Summary:** npm installation silently persists a Karajan MCP server into Claude Code and Codex user configuration. Starting either agent subsequently launches package code.

- **Trigger:** npm install

- **Impact:** Unconsented persistent AI-agent control-surface extension

- **Evidence paths:** package.json, scripts/postinstall.js, src/mcp/server.js, src/mcp/tools.js

- **Review source:** ai\_review

- **Reviewed:** 2026-07-23T11:06:10.465Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** postinstall mutation of foreign AI-agent MCP configuration

- **Attack narrative:** The postinstall hook automatically adds a karajan-mcp stdio server to both Claude Code and Codex user-level configuration without prompting. Those entries execute this package's MCP server on later agent startup, creating persistence in broad external AI-agent control surfaces. This is the concrete install-time behavior prohibited by policy.

- **Rationale:** Source inspection confirms an unconsented postinstall mutation of ~/.claude.json and ~/.codex/config.toml. This meets the blocking AI-agent control-hijack boundary regardless of the scanner similarity hint.

- **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 on npm install., scripts/postinstall.js silently writes ~/.claude.json MCP configuration., scripts/postinstall.js writes ~/.codex/config.toml and registers a local server., The injected MCP command executes src/mcp/server.js when either agent starts.

- **Evidence against:** The injected MCP server uses stdio; no install-time network endpoint was found., scripts/install.js MCP setup is user-invoked, but does not mitigate postinstall.
