Overview

AI-generated overview

Hosted MaxMind minFraud server that lets an assistant score transactions for fraud risk and report real-world outcomes.

What you can do
  • Score a transaction for fraud risk and get the overall score, IP risk and disposition
  • Get detailed insights: IP geolocation, email, address and device attributes with per-component risk
  • Get the most detailed assessment with risk score reasons and per-factor subscores
  • Report a transaction outcome (such as chargeback or confirmed fraud) back to MaxMind
  • Check monthly usage and manage the subscription plan
When to use it
Useful when you want an assistant to vet orders, signups or payments for fraud risk while working in chat, and to feed confirmed outcomes back so scoring improves.
Requirements
Remote endpoint at maxmind-minfraud.usefulapi.io/mcp; no local install. Sign-in uses OAuth, and the login page asks for your MaxMind account ID and license key, which are validated and stored per user. Add only the URL to the client config.
Before you install
You supply MaxMind account ID and license key at login; do not put them or an Authorization header in the client config. The report tool writes fraud feedback to MaxMind and changes its model of your traffic, so confirm before running it. Free plan is limited to 50 calls a month; paid plans are billed through Stripe checkout links, and cancelling gives no refund for the current period.

Installation

In SourceWeft

  1. Open MaxMind minFraud MCP by usefulapi in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.usefulapi%2Fmaxmind-minfraud/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

minfraud_report_transaction

Report a transaction outcome

WRITE — submits fraud feedback to MaxMind. Report the real-world outcome of a transaction (e.g. it was a chargeback or confirmed fraud) so minFraud can improve future scoring. This mutates MaxMind's model of your traffic; it is not a read. Requires a `tag` and at least one identifier (ip_address, maxmind_id, minfraud_id, or transaction_id). API: POST /minfraud/v2.0/transactions/report (returns HTTP 204).
