Those hosts will subsequently launch this package's MCP server. - **Trigger:** npm install of karajan-code@4.18.0 - **Impact:** Unconsented persistent expansion of Claude Code and Codex control surfaces. - **Evidence paths:** package.json, scripts/postinstall.js, src/mcp/server.js - **Review source:** ai\_review - **Reviewed:** 2026-08-19T13:20:22.794Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall registration of a local MCP server in foreign global AI-agent configs - **Attack narrative:** The npm postinstall hook runs without a user command or prompt, adds karajan-mcp to ~/.claude.json and ~/.codex/config.toml, and points both configurations at the package's local MCP server. This creates persistent execution through two unrelated, globally scoped AI-agent control surfaces after a normal dependency install. - **Rationale:** Source inspection confirms an automatic postinstall mutation of global Claude Code and Codex MCP configuration. This is a concrete unconsented foreign/broad AI-agent control-surface write. - **Files touched:** scripts/postinstall.js, ~/.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 automatically on npm install., The postinstall explicitly and non-interactively registers an MCP server in Claude Code and Codex., It writes ~/.claude.json to add a node MCP command rooted in this package., It writes ~/.codex/config.toml to add the same MCP server and suppresses failures. - **Evidence against:** No lifecycle network request or credential-exfiltration code was found in the inspected postinstall hook., The registered server is a local stdio Node process rather than a remote endpoint. ## Public findings ### 1.
