This connects Claude to MaxMind's minFraud fraud detection API through Membrane's auth layer. You'd use it when building e-commerce or payment flows where you need risk scores on transactions before processing them. The skill handles the usual fraud signals like email reputation, shipping/billing mismatches, device fingerprinting, and credit card data. Membrane takes care of credential management so you're not juggling API keys. The action discovery is helpful since minFraud's API surface is fairly specific to fraud use cases. Worth noting this requires a Membrane account, though free tier works fine.
