AgentPay MCP: Open-source MCP payment server for AP2 scenarios #178
Description
What
AgentPay MCP is an open-source MCP server that gives AI agents payment capabilities via the Model Context Protocol. It provides wallet management, payment authorization, and transaction execution for agent-to-service payments.
Why this is relevant to AP2
The current AP2 samples use ADK + Gemini, which works well for the Google ecosystem. AgentPay MCP demonstrates AP2-compatible payment flows through the MCP standard, making agent payments accessible to any MCP-compatible agent (Claude, GPT-4, Gemini, open-source LLMs).
What we could contribute
- A new sample scenario showing AP2 payment flows via MCP tooling
- Integration with the Agent Wallet SDK for non-custodial wallet management (ERC-4337)
- x402 payment handling as an AP2 settlement option alongside card rails
Stack
TypeScript, MCP protocol, ERC-4337 smart contract wallets, x402 compatible.
Test Coverage
- 154 smart contract tests passing
- 113 SDK tests passing
- Published on npm
Happy to sign the CLA and submit a PR with a sample scenario if this aligns with the project's direction.
