Ap2 MCP Server

AP2 (Agent-to-Agent Payment Protocol) is Google's open framework for authorization, audit, and trust in agentic payments. It answers the critical questions: Who authorized this payment? What limits apply? What's the full audit trail?. Its 22 documented tools cover payment, agent, mandate, verify.

People connecting finance tools to Claude, Cursor, VS Code, or another MCP client. The project is written in JavaScript.

One of 127 MCP servers published from codespar/mcp-dev-latam. Stars and repository activity are shared across all of them. See all 127 →
