It registers a package-supplied MCP server that will run under those AI-agent clients. - **Trigger:** npm install of karajan-code - **Impact:** Persistent execution of the package MCP server through Claude Code and Codex. - **Evidence paths:** package.json, scripts/postinstall.js, src/mcp/server.js, packages/ai-trash/src/install.js - **Review source:** ai\_review - **Reviewed:** 2026-08-08T14:06:33.324Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** unconsented cross-agent MCP configuration injection - **Attack narrative:** The postinstall hook runs without user interaction, reads or creates ~/.claude.json and ~/.codex/config.toml, and inserts a karajan-mcp configuration pointing to this package's src/mcp/server.js. This mutates broad, foreign AI-agent control surfaces at install time and causes later agent-client launches to execute package code. - **Rationale:** This is concrete unconsented postinstall mutation of foreign AI-agent configuration, meeting the blocking policy. Explicit-user ai-trash setup does not mitigate the independent postinstall behavior. - **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 unconditionally rewrites ~/.claude.json., scripts/postinstall.js creates/rewrites ~/.codex/config.toml., Both configs register karajan-mcp to execute package src/mcp/server.js. - **Evidence against:** The MCP server uses stdio; no install-time network endpoint is present., packages/ai-trash config mutation requires an explicit kj-trash install --claude-code command. ## Public findings ### 1.
