Pick Crossmint when
- Your agent's job is on-chain or you want stablecoin rails.
- You need wallet + card + verifiable credentials in one place.
- You're comfortable with a broader integration surface.
Pick CardForAgent when
- You want one card, accessed over MCP, settled in fiat.
- You don't want to think about chains, wallets, or stablecoins.
- You value "tiny tool that does one job" over "full stack platform".

Honest take
Crossmint is doing more — but if you don't need everything they do, that breadth becomes weight. Pick by whether your agent's actual workload is on-chain.
