AgentPay MCP
Compatible with x402 V1/V2 + Stripe MPP — protocol-agnostic spend controls.
agentpay-mcp is the human-first trust and policy layer above commodity execution rails (x402, ACP, UCP). OWS-compatible trust layer -- works on top of MoonPay Open Wallet Standard. Protocol-agnostic trust layer -- works with x402 AND Stripe MPP. While x402 settles $600M annualized — with AI agents driving 40% of protocol activity (March 2026) — the missing piece isn't payment execution. It's governance: who approved it, how much can be spent, and what happens when the agent tries to exceed its budget. That's what agentpay-mcp provides.
ACP handles what agents SELL. agentpay-mcp handles what agents BUY. ACP (Agent Commerce Protocol) enables agents to list services, negotiate, and receive payments. agentpay-mcp is the complementary layer — controlling what agents spend when consuming paid APIs, tools, and services. Different problems, compatible solutions.
When your agent hits HTTP 402 Payment Required, it needs to pay and retry — with your approval, within limits you set. AgentPay MCP is a Model Context Protocol server that gives Claude, Cursor, and any MCP-compatible agent a payment wallet with hard spend caps, human-approval mode, and a full on-chain audit trail.
