This is a well-architected x402-gated MCP relay server with proper payment authentication and reasonable permission scope. The server correctly requires signed cryptographic proofs (EIP-3009 USDC transfers) for paid operations and uses environment variables for credentials. Minor code quality issues around error handling and input validation are present but do not indicate security vulnerabilities. Supply chain analysis found 4 known vulnerabilities in dependencies (0 critical, 3 high severity). Package verification found 1 issue.

From the project's GitHub README.
A thin REST + MCP relay that exposes Qwen/Qwen3.6-35B-A3B (served by OpenAI-compatible inference behind the scenes) to overseas agents, gated by the x402 micropayment protocol on Base L2 (USDC).
No accounts. No website. No human UI. An autonomous agent discovers the
endpoint, gets a 402 Payment Required, signs an EIP-3009 USDC transfer in
the PAYMENT-SIGNATURE header, and retries — that's it.
