CRITICALnpm lifecycle script — runs automatically on install
repo/package.json:20
"prepare": "npm run build",
"postinstall": "npm run install-solana",
"install-solana": "npm install -g @solana/cli@latest --yes --silent || echo 'Solana CLI installation failed, but MCP will work with web3.js'",Why was this flagged?
npm lifecycle scripts like postinstall run automatically during package installation with no user interaction required. This is the #1 attack vector for malicious npm packages — attackers embed data theft or backdoor installation in these hooks. Rated CRITICAL because code executes before the developer can review it.
