YRUZ x402 tools MCP Server

Audit a project in one call: send package-lock.json (v2/v3), package.json, composer.lock, composer.json or requirements.txt. Lockfiles give exact direct and transitive versions; manifest ranges are resolved to the highest satisfying version and labelled so; unpinned requirements are listed as unresolved. Returns every affected package with advisories, severity, fixed versions and the smallest fixing upgrade, plus coverage limits. Up to 300 packages per audit. Price: 0.025 USDC per call, paid with x402 (USDC on Base or Solana, no account, no API key); invalid input is refused before payment and a failed run is never charged.
