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.

MaxMind minFraud

MaxMind minFraud is a service that helps businesses prevent online fraud. It uses a risk score and other data points to assess the likelihood of a transaction being fraudulent, helping e-commerce sites and other online businesses reduce fraud losses.

Working with MaxMind minFraud

This skill uses the Membrane CLI to interact with MaxMind minFraud. Membrane handles authentication and credentials refresh automatically — so you can focus on the integration logic rather than auth plumbing.

Install the CLI

Install the Membrane CLI so you can run membrane from the terminal:

npm install -g @membranehq/cli@latest

Authentication

membrane login --tenant --clientName=<agentType>

This will either open a browser for authentication or print an authorization URL to the console, depending on whether interactive mode is available.
