MCP Server

An MCP server deployed as a Cloudflare Worker, exposing a paid tool callable from Claude via the Coinbase Payments MCP. Payment is handled transparently via x402 — the tool call triggers a payment cycle without any manual wallet interaction.

This demo closes the loop between three ecosystems: Anthropic's MCP protocol, Coinbase's x402 payment infrastructure, and Cloudflare Workers. The implementation reference is docs.x402.org/guides/mcp-server-with-x402.

Demo 04 ships after Demos 01 and 02 are live and the x402 GitHub ecosystem listing has been submitted. The institutional visibility ceiling of this demo — closing the Anthropic/Coinbase/Cloudflare triangle — makes it the highest-leverage piece in the Phase 3 roadmap.
