Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "moonpay": {
      "command": "npx",
      "args": [

@codespar/mcp-moonpay

MCP server for MoonPay — fiat-to-crypto on/off-ramp.

MoonPay spans 100+ crypto assets and many geographies, with both buy (fiat → crypto) and sell (crypto → fiat) flows. Pix is supported as a Brazil onramp rail.

@codespar/mcp-circleUSDC native railsStablecoin infra

Use MoonPay when an agent needs broader crypto coverage (beyond USDC), longer-tail geographies, or a sell-side flow that pays out to local fiat.
