MCP Billing Gateway

This is a hosted billing proxy that sits between AI agents and your MCP servers to handle payments without writing billing code. You register as an operator, point it at your upstream MCP server URL, set a pricing plan (per-call credits or Stripe subscriptions), and get a proxied endpoint that enforces payment before forwarding requests. It supports traditional Stripe API keys and x402 crypto micropayments in USDC on Base for agent-to-agent transactions. The local package just exposes a get_billing_info tool for service discovery. The real work happens on the hosted Railway instance where you manage servers, track usage, and collect revenue through an operator dashboard. Reach for this when you want to monetize an existing MCP server without building payment infrastructure yourself.
