It adds MCP entries, including an npx command that resolves and runs a latest remote package. - **Trigger:** npm installation or update of this package as a project dependency. - **Impact:** A consumer's JoyCode or Cursor agent can be configured to launch package-provided servers and a remotely resolved Playwright MCP release without an explicit setup command. - **Evidence paths:** package.json, bin/postinstall.js, lib/install.js - **Review source:** ai\_review - **Reviewed:** 2026-08-31T16:33:29.258Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall-driven AI-agent configuration mutation and remote MCP launcher registration. - **Attack narrative:** The package's postinstall hook calls its installer with both JoyCode and Cursor integrations enabled. That installer creates or overwrites project MCP configuration and registers three servers. One server runs npx with @playwright/mcp@latest, so a future registry release is fetched and executed when the configured agent starts it. This is an unconsented install-time mutation of broad AI-agent control surfaces. - **Rationale:** The automatic lifecycle hook changes foreign AI-agent configuration and introduces a moving remote command path. This meets the install-control-surface blocking policy. - **Files touched:** package.json, bin/postinstall.js, lib/install.js, .joycode/mcp.json, .cursor/mcp.json, mcp/proto-version-server.js, mcp/line-repos-server.js - **Network endpoints:** registry.npmjs.org ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The manifest runs a postinstall hook automatically., The hook invokes update with JoyCode, Cursor, agent, and version integration enabled., The installer writes MCP configuration into both JoyCode and Cursor project control directories., It registers an MCP server that launches the moving latest Playwright MCP package through npx without a user command. - **Evidence against:** The local version service binds to loopback only., No credential collection or data exfiltration was found in the inspected install path. ## Public findings ### 1.
