A remote MCP server that simulates payments end to end. Connect it to an assistant, ask for a payment, and watch it move through the same statuses a real one would.
How it works
One real example, start to finish: a CHAPS payment asked for in plain English. Everything shown is the sandbox engine's actual output.
Connect
You need an account on this sandbox. Sign-in happens in your browser the first time you connect.
Claude Code
Run this once, then use /mcp to sign in.
