# Billing Gateway

> Use this tool when you need to monetize your MCP servers with flexible payment options, as it applies billing logic to incoming requests and supports both traditional and crypto payments through Stripe and x402. It solves the problem of implementing billing infrastructure, allowing developers to focus on their core application. The Billing Gateway accepts environment variables as input and outputs forwarded requests to the upstream MCP server.

## Description

Billing Gateway acts as a proxy layer that intercepts MCP server requests and applies billing logic before forwarding them. It supports both Stripe for traditional payments and x402 for crypto micropayments in USDC, enabling developers to monetize their MCP servers without implementing billing infrastructure. Configuration is handled through environment variables pointing to the upstream MCP server.
