MCPay is open-source infrastructure that adds on-chain payments to any Model Context Protocol (MCP) server using the x402 \"Payment Required\" protocol. It enables MCP clients — such as ChatGPT, Cursor, and others — to make pay-per-call requests instead of relying on static subscriptions or API keys. The goal is to let AI agents and applications pay only for what they use, automatically and transparently. --- Why MCPay (in 30 seconds) Clients → Pay only for what they use — no subscriptions, no keys, no setup. Works out of the box with MCP-compatible apps (ChatGPT, Cursor, and more). Developers → Monetize and get discovered instantly using our SDK (or a compatible one), monetization wrapper, or public index. Set per-call, per-token, or dynamic pricing and receive payments automatically. Agents → Perform real agent↔service micropayments , enabling autonomous access to APIs, inference, data, and more. --- How it works MCPay handles the entire payment lifecycle transparently for both developers and clients: - Follows x402 protocol with structured price metadata. - Accepts and verifies the on-chain payment, then automatically retries the original MCP request once confirmed. - Streams usage and revenue events to dashboards and analytics endpoints. This mechanism ensures that any MCP-compatible app or agent can pay per call — either directly (via wallet) or through a ","default_branch":null,"files":null,"tree":[],"storefront":"/r/microchipgnu","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/microchipgnu/MCPay/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
