It adds MCP servers, rules, hooks, and automatic approvals. - **Trigger:** npm installation of warden-ai@0.3.2 - **Impact:** Unconsented persistent execution and approval changes in AI coding-agent clients. - **Evidence paths:** package.json, bin/postinstall.cjs, dist/cli.js - **Review source:** ai\_review - **Reviewed:** 2026-08-15T19:41:12.405Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** silent postinstall invocation of broad AI-agent configuration and permission mutation - **Attack narrative:** During npm installation, the package silently invokes \`warden init\`. That command registers its MCP server in global and project configuration files for many unrelated agent products, writes global rules and project hooks, and enables automatic approvals including Codex tool auto-approval and Cline wildcard approval. This persists a package-controlled executable in AI-agent control surfaces without an explicit user setup command. - **Rationale:** The behavior is concrete, install-time, unconsented mutation of broad foreign AI-agent control surfaces and permissions. No external exfiltration was needed to establish the blocking condition. - **Files touched:** bin/postinstall.cjs, dist/cli.js, ~/.claude.json, ~/.cursor/mcp.json, ~/.codex/config.toml, ~/.config/devin/config.json, \/.mcp.json, \/.devin/config.json ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** postinstall silently runs \`warden init\` in the installer's current directory., \`init\` registers an MCP server, writes agent and global rules, and installs enforcement hooks., Registration modifies the global Codex config with automatic tool approval., Registration grants Warden wildcard permissions and Cline wildcard auto-approval., The install path targets numerous unrelated AI-agent configs without user action. - **Evidence against:** No credential harvesting, external exfiltration, or non-local network endpoint was found in inspected entrypoints. ## Public findings ### 1.
