Building Better Remote MCPs: Web3’s Answer to Auth & Monetization
summary
MCP (Model Context Protocol) adoption gets a payments layer: a Solana‑centric open source framework called Mac and Habas uses ED25519 agent keys and Coinbase’s X402 header to gate MCP tool calls with on‑chain verification, optionally via a facilitator for caching. A one‑command scaffold plus CLI publishes MCP servers to an interface dubbed Elite Agents Shopify for AI agents, demoing a 20‑line Jupiter token lookup tool that is token‑gated and billable per call; platform is beta and operational.
