🔌 MCP Serversapph1re
Add Stripe, credits, and crypto billing to any MCP server with zero code.
mcp-billing-gateway-sdk addresses one of the most overlooked challenges in the MCP ecosystem: monetization. Built by sapph1re, this SDK acts as a billing gateway that sits in front of any MCP server, wrapping tool calls with payment enforcement logic. Key capabilities include Stripe subscription support for recurring revenue models, per-call credit systems for metered usage, tiered pricing structures to accommodate different customer segments, and x402 crypto micropayments enabling pay-per-request on-chain settlement. The operator dashboard provides a visual interface for monitoring revenue, managing subscribers, and configuring pricing tiers. The x402 protocol integration is particularly notable as it leverages the HTTP 402 status code standard for machine-to-machine crypto payments, positioning the SDK at the intersection of AI tooling and decentralized payment infrastructure. By abstracting away billing complexity, it allows MCP server developers to focus on their core AI tools while still building sustainable revenue streams.
