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.
