Built for AI

Your AI assistant can run fraud checks.

FraudCheck ships a native MCP server — the open protocol AI assistants use to call external tools. Connect it once with your API key, and Claude, ChatGPT, Grok, Gemini, Cursor, or any MCP-capable agent can screen an order, look up an IP, or run a sanctions check mid-conversation. Same checks, same limits, same billing as the REST API.

Connect your assistant

Claude Code:

claude mcp add --transport http fraudcheck https://fraudcheckapi.com/mcp --header "X-Api-Key: YOUR_API_KEY"

Or any MCP client that takes a JSON config:

{
  "mcpServers": {
    "fraudcheck": {
      "type": "http",
      "url": "https://fraudcheckapi.com/mcp",
      "headers": { "X-Api-Key": "YOUR_API_KEY" }
    }
  }
}

Assistant	How to connect
Claude Code	Run the one-line command above.
ChatGPT	Settings → Connectors → add a custom connector with the URL https://fraudcheckapi.com/mcp, choose API key authentication, and paste your key.
Grok	grok.com/connectors → New Connector → Custom → enter the same URL and your API key.
Gemini CLI	Add the JSON config above to your MCP settings (~/.gemini/settings.json, using httpUrl).
Cursor, VS Code & others	Paste the JSON config above into the client's MCP settings — any client that supports remote MCP servers works.

Then just ask: "Screen this order — IP 9.9.9.9, email [email protected], shipping to DE." The assistant calls the tools and reads back the checks.

The tools your assistant gets

Tool	What it does
screen	The full composite: any mix of IP, email, phone, shipping country and name in one call — per-check results, reason codes, advisory score.
check_ip	Country, network operator, Tor / VPN / datacenter / hostile-network flags, proxy likelihood.
check_email	Syntax, deliverability, sender-authentication records, disposable / role / free-mail detection.
check_phone	Validity, line type, region and carrier metadata, recent scam-report flag.
check_name	Sanctions screening of people and companies, including known aliases.
geolocate	Full IP geolocation: country, region, city, coordinates, time zone.
list_reason_codes	The live reason-code catalog with current weights and meanings.

Machine-readable everything

Agents and tooling can discover the whole API without a human in the loop:

/.well-known/mcp/server-card.json	MCP server discovery
/.well-known/api-catalog	API catalog (RFC 9727)
/openapi/v1.json	Full OpenAPI specification
/llms.txt	LLM-friendly product overview
/.well-known/oauth-authorization-server	OAuth discovery metadata

MCP calls use your normal API key and count toward your plan like any REST call — nothing separate to set up or pay for.

Results are derived from publicly available databases and are provided as-is. Checks, not verdicts — your assistant reads them; you make the call.
