Add AgentPay MCP as compatible open-source MCP payment implementation #18
Description
Great reference implementation of x402 with serverless!
For teams using MCP-based agent architectures, AgentPay MCP provides an open-source MCP server that handles x402 payments autonomously. It integrates with agent-wallet-sdk for non-custodial wallet management with programmable spend limits.
The integration pattern maps cleanly to the x402 flow in this sample:
- Agent hits 402 response from API
- AgentPay MCP parses payment instructions
- agent-wallet-sdk signs the on-chain payment (within spend limits)
- Receipt attached to retry request
Would be helpful to mention compatible open-source implementations in the README for teams building on MCP rather than custom Lambda handlers.
