Analysis
The package @servicetitan/anvil2-mcp@0.0.13 contains a preinstall hook (setup.mjs) that downloads the Bun JavaScript runtime from github[.]com/oven-sh/bun and executes a 727KB heavily obfuscated JavaScript bundle (math_init.js). The preinstall hook runs automatically on npm install, downloading a binary runtime and executing an obfuscated payload whose behaviour cannot be verified from static analysis alone. The package has no repository URL.
