Handshake58

MCP server for the DRAIN payment protocol. Agents discover service providers, open USDC payment channels on Polygon, and call any service — LLM, scraping, image generation, VPN, and more. Pay per use, no API keys, no subscriptions.

Build and integrate DRAIN providers for the Handshake58 marketplace. Use when the user wants to add a new provider, integrate an API, wrap a service, or build a custom tool as a paid DRAIN provider. Covers LLM proxies, API wrappers, and self-built services.
