This guide walks you through the easiest and most secure way to connect your Fraudlabs pro account to Claude via Composio Connect, enabling it to screen this new order for fraud risk, send SMS OTP to verify customer phone, get analysis result for order 123456, and more such actions on your behalf without compromising your account security.

Setup is the same on Claude Web, Desktop, and Cowork, and you only need to do it once. The connector is tied to your account, so it's available in all three.

What is the Fraudlabs pro Claude Connector, and what's possible with it?

The Fraudlabs pro MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Fraudlabs Pro account. It provides structured and secure access to your fraud detection and order screening tools, so your agent can perform actions like screening transactions, sending SMS OTPs, retrieving fraud analysis results, and managing reseller subscriptions on your behalf.

  • Real-time fraud screening for orders: Instantly have your agent assess the risk of new transactions before fulfillment to minimize chargebacks and detect suspicious activity.
  • Automated SMS OTP verification: Directly send one-time passwords to customers via SMS and verify phone numbers for added transaction security.
  • Retrieve and analyze fraud results: Quickly pull fraud analysis reports on previously screened orders for smarter decision-making and audit trails.
  • Feedback and continuous learning: Submit order feedback—approved or rejected—to improve future fraud detection accuracy and adapt to evolving threats.
  • Reseller account management: Automate account creation and manage subscription plans for resellers directly from your agent, streamlining onboarding and upgrades.

Troubleshooting

1. Why does Claude not use the Composio connector for Fraudlabs pro?

The connector can show as connected, but Claude must use it in each Fraudlabs pro conversation.

  • Click + at the lower left of the chat, or type /.
  • Hover Connectors.
  • Turn on Composio.
  • Ask Claude to connect to Fraudlabs pro again.

2. Why does Claude show an MCP server error before Fraudlabs pro connects?

Claude can show Couldn't reach the MCP server or Authorization with the MCP server failed when you add the connector for Fraudlabs pro.

  • Check that the connector URL is https://connect.composio.dev/mcp.
  • Connectors run from Anthropic's cloud, so your device network is usually not the problem.
  • Add the connector again from Customize > Connectors, then ask Claude to connect Fraudlabs pro.
  • If it fails again, send the error and the ofid_ reference id to support@composio.dev.

3. Why does the Fraudlabs pro authorization link not work?

The Composio connector is one server. Your Fraudlabs pro account connects separately when Claude asks for it.

  • If the browser does not open, or the link expires, ask Claude to retry the Fraudlabs pro connection.
  • Composio creates a fresh Fraudlabs pro authorization link.
  • Open that link in your browser and finish the Fraudlabs pro sign-in.

4. Why do Fraudlabs pro actions fail after they worked before?

The Fraudlabs pro connection can expire or lose permission.

  • Ask Claude to inspect the Fraudlabs pro connection.
  • If the connection is unhealthy, disconnect it when Claude prompts you.
  • Reconnect the Fraudlabs pro account and retry the action.
  • If Claude shows a permission prompt, approve it before Claude changes data in Fraudlabs pro.
  • If the action still fails with a permission error, check that the connected account has that permission in Fraudlabs pro itself.

5. How do I switch to a different Fraudlabs pro account?

Claude can manage the Fraudlabs pro connection for you.

  • Ask Claude to disconnect or delete the current Fraudlabs pro account.
  • Ask Claude to connect Fraudlabs pro again.
  • Open the new Composio authorization link for Fraudlabs pro.
  • Sign in with the other Fraudlabs pro account in the browser.
  • After the account connects, ask Claude to retry the Fraudlabs pro task.

6. Why is my Fraudlabs pro connection missing in Claude Desktop or on a Team plan?

The connector belongs to your Claude account, so your Fraudlabs pro connection works in Claude Web, Desktop, and Cowork.

  • In Claude Desktop, open Customize > Connectors.
  • Next to Composio, click and click Clear cache.
  • If Fraudlabs pro tools still do not appear, click , disconnect, remove the connector, and add it again.
  • On Team or Enterprise, an Owner or Primary Owner must enable the connector before you can connect Fraudlabs pro.

FAQ

Frequently asked questions

With a standalone Fraudlabs pro MCP server, the agents and LLMs can only access a fixed set of Fraudlabs pro tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Fraudlabs pro and many other apps based on the task at hand, all through a single MCP endpoint.

Yes, you can. Claude Cowork fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Fraudlabs pro tools.

Yes, absolutely. You can configure which Fraudlabs pro scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.

All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Fraudlabs pro data and credentials are handled as safely as possible.
