@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.

Positioning vs the rest of the catalog

Server	Coverage	Direction
@codespar/mcp-unblockpay	BRL / MXN ↔ USDC	Onramp + offramp, stablecoin only
@codespar/mcp-moonpay	100+ crypto assets, multi-geo, Pix for BR	Onramp + offramp
@codespar/mcp-mercado-bitcoin, @codespar/mcp-bitso	Exchange order books	Trade
@codespar/mcp-circle	USDC native rails	Stablecoin 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.
