Summary
Connects Claude to your StablecoinX merchant account for headless payment operations. You get auth via email OTP, API key management, payment session creation, paymaster configuration with allowlists, and webhook setup. Built on ERC-4337 for gas sponsorship and includes non-custodial treasury features. Reach for this when you need Claude to handle checkout flows, manage stablecoin payments, or configure gas sponsorship rules without bouncing between the merchant dashboard. Setup is straightforward with npx, requiring only a state passphrase since endpoints are bundled. Runs over stdio transport.
