## Introduction

This guide walks you through connecting Fraudlabs pro to Mastra AI using the Composio tool router. By the end, you'll have a working Fraudlabs pro agent that can screen this new order for fraud risk, send sms otp to verify customer phone, get analysis result for order 123456 through natural language commands.
This guide will help you understand how to give your Mastra AI agent real control over a Fraudlabs pro account through Composio's Fraudlabs pro MCP server.
Before we dive in, let's take a quick look at the key ideas and tools involved.

## TL;DR

Here's what you'll learn:
- Set up your environment so Mastra, OpenAI, and Composio work together
- Create a Tool Router session in Composio that exposes Fraudlabs pro tools
- Connect Mastra's MCP client to the Composio generated MCP URL
- Fetch Fraudlabs pro tool definitions and attach them as a toolset
- Build a Mastra agent that can reason, call tools, and return structured results
- Run an interactive CLI where you can chat with your Fraudlabs pro agent

## What is Mastra AI?

Mastra AI is a TypeScript framework for building AI agents with tool support. It provides a clean API for creating agents that can use external services through MCP.
Key features include:
- MCP Client: Built-in support for Model Context Protocol servers
- Toolsets: Organize tools into logical groups
- Step Callbacks: Monitor and debug agent execution
- OpenAI Integration: Works with OpenAI models via @ai-sdk/openai

## What is the Fraudlabs pro MCP server, 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.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `FRAUDLABS_PRO_CREATE_ACCOUNT` | Create FraudLabs Pro Reseller Sub-Account | Creates a new FraudLabs Pro user account under a reseller account. Requires a Reseller API key (not a regular API key). Use this action to provision new sub-accounts for customers when operating as a FraudLabs Pro reseller. Returns account credentials (username and password) upon successful creation. Prerequisites: - Must have a FraudLabs Pro Reseller account (apply at https://www.fraudlabspro.com/reseller/program) - Requires valid Reseller API key (different from standard FraudLabs Pro API key) - All required fields must contain valid data matching FraudLabs Pro validation rules Important: - Phone numbers should contain only digits (no +, -, spaces, or parentheses) - Country must be valid ISO 3166-1 alpha-2 code (e.g., US, GB, CA) - Industry must be a valid ID from 1-14 |
| `FRAUDLABS_PRO_FLP_FEEDBACK_ORDER` | FLP Feedback Order | Submit fraud screening feedback to improve FraudLabs Pro's machine learning model. Use this after reviewing a screened order to mark it as approved, rejected, or blacklisted. This feedback trains the algorithm to better detect fraud patterns in future transactions. |
| `FRAUDLABS_PRO_FLP_SCREEN_ORDER` | FraudLabs Pro Screen Order | Tool to screen orders for fraud. Use when you need to assess transaction risk before fulfillment. |
| `FRAUDLABS_PRO_GET_ORDER_RESULT2` | Get FraudLabs Pro Order Result (v2) | Tool to retrieve an existing transaction from FraudLabs Pro fraud detection system using the v2 API. This API is only available for paid plans. |
| `FRAUDLABS_PRO_GET_SMS_VERIFICATION_RESULT` | Get SMS Verification Result | Verify an OTP (one-time password) received via SMS. Returns 'Y' if the OTP is valid, 'N' if invalid or expired. Must be called after using Send SMS Verification to obtain a transaction ID. |
| `FRAUDLABS_PRO_SEND_SMS_VERIFICATION` | Send SMS OTP Verification | Sends an SMS message containing a one-time password (OTP) to verify a user's phone number. The API generates a random 6-digit OTP, replaces the placeholder in your message template, and sends the SMS to the recipient. Returns a transaction ID that you must use with the Get SMS Verification Result action to verify the OTP the user enters. Testing: Use phone number '+11' for sandbox testing (no credits deducted). For verification testing with sandbox number, use OTP '123456'. |
| `FRAUDLABS_PRO_SUBSCRIBE_PLAN` | Subscribe Reseller Plan | Tool to subscribe a reseller account to a specific plan. Use after obtaining a reseller API key and selecting a plan. Example: Subscribe user "john_doe" to the MICRO plan. |
| `FRAUDLABS_PRO_WEBHOOK_ORDER_STATUS_CHANGED` | Test Order Status Changed Webhook Delivery | Tool to send a test webhook payload to the provided callback URL for FraudLabs Pro order status change notifications. This helps validate your endpoint behavior. Important: FraudLabs Pro webhook registration must be configured manually via dashboard. |

## Creating MCP Server - Stand-alone vs Composio SDK

The Fraudlabs pro MCP server is an implementation of the Model Context Protocol that connects your AI agent to Fraudlabs pro. It provides structured and secure access so your agent can perform Fraudlabs pro operations on your behalf through a secure, permission-based interface.
With Composio's managed implementation, you don't have to create your own developer app. For production, if you're building an end product, we recommend using your own credentials. The managed server helps you prototype fast and go from 0-1 faster.

## Step-by-step Guide

### 1. Prerequisites

Before starting, make sure you have:
- Node.js 18 or higher
- A Composio account with an active API key
- An OpenAI API key
- Basic familiarity with TypeScript

### 1. Getting API Keys for OpenAI and Composio

OpenAI API Key
- Go to the [OpenAI dashboard](https://platform.openai.com/settings/organization/api-keys) and create an API key.
- You need credits or a connected billing setup to use the models.
- Store the key somewhere safe.
Composio API Key
- Log in to the [Composio dashboard](https://dashboard.composio.dev?utm_source=toolkits&utm_medium=framework_docs).
- Go to Settings and copy your API key.
- This key lets your Mastra agent talk to Composio and reach Fraudlabs pro through MCP.

### 2. Install dependencies

Install the required packages.
What's happening:
- @composio/core is the Composio SDK for creating MCP sessions
- @mastra/core provides the Agent class
- @mastra/mcp is Mastra's MCP client
- @ai-sdk/openai is the model wrapper for OpenAI
- dotenv loads environment variables from .env
```bash
npm install @composio/core @mastra/core @mastra/mcp @ai-sdk/openai dotenv
```

### 3. Set up environment variables

Create a .env file in your project root.
What's happening:
- COMPOSIO_API_KEY authenticates your requests to Composio
- COMPOSIO_USER_ID tells Composio which user this session belongs to
- OPENAI_API_KEY lets the Mastra agent call OpenAI models
```bash
COMPOSIO_API_KEY=your_composio_api_key_here
COMPOSIO_USER_ID=your_user_id_here
OPENAI_API_KEY=your_openai_api_key_here
```

### 4. Import libraries and validate environment

What's happening:
- dotenv/config auto loads your .env so process.env.* is available
- openai gives you a Mastra compatible model wrapper
- Agent is the Mastra agent that will call tools and produce answers
- MCPClient connects Mastra to your Composio MCP server
- Composio is used to create a Tool Router session
```typescript
import "dotenv/config";
import { openai } from "@ai-sdk/openai";
import { Agent } from "@mastra/core/agent";
import { MCPClient } from "@mastra/mcp";
import { Composio } from "@composio/core";
import * as readline from "readline";

import type { AiMessageType } from "@mastra/core/agent";

const openaiAPIKey = process.env.OPENAI_API_KEY;
const composioAPIKey = process.env.COMPOSIO_API_KEY;
const composioUserID = process.env.COMPOSIO_USER_ID;

if (!openaiAPIKey) throw new Error("OPENAI_API_KEY is not set");
if (!composioAPIKey) throw new Error("COMPOSIO_API_KEY is not set");
if (!composioUserID) throw new Error("COMPOSIO_USER_ID is not set");

const composio = new Composio({
  apiKey: composioAPIKey as string,
});
```

### 5. Create a Tool Router session for Fraudlabs pro

What's happening:
- create spins up a short-lived MCP HTTP endpoint for this user
- The toolkits array contains "fraudlabs_pro" for Fraudlabs pro access
- session.mcp.url is the MCP URL that Mastra's MCPClient will connect to
```typescript
async function main() {
  const session = await composio.create(
    composioUserID as string,
    {
      toolkits: ["fraudlabs_pro"],
    },
  );

  const composioMCPUrl = session.mcp.url;
  console.log("Fraudlabs pro MCP URL:", composioMCPUrl);
```

### 6. Configure Mastra MCP client and fetch tools

What's happening:
- MCPClient takes an id for this client and a list of MCP servers
- The headers property includes the x-api-key for authentication
- getTools fetches the tool definitions exposed by the Fraudlabs pro toolkit
```typescript
const mcpClient = new MCPClient({
    id: composioUserID as string,
    servers: {
      nasdaq: {
        url: new URL(composioMCPUrl),
        requestInit: {
          headers: session.mcp.headers,
        },
      },
    },
    timeout: 30_000,
  });

console.log("Fetching MCP tools from Composio...");
const composioTools = await mcpClient.getTools();
console.log("Number of tools:", Object.keys(composioTools).length);
```

### 7. Create the Mastra agent

What's happening:
- Agent is the core Mastra agent
- name is just an identifier for logging and debugging
- instructions guide the agent to use tools instead of only answering in natural language
- model uses openai("gpt-5") to configure the underlying LLM
```typescript
const agent = new Agent({
    name: "fraudlabs_pro-mastra-agent",
    instructions: "You are an AI agent with Fraudlabs pro tools via Composio.",
    model: "openai/gpt-5",
  });
```

### 8. Set up interactive chat interface

What's happening:
- messages keeps the full conversation history in Mastra's expected format
- agent.generate runs the agent with conversation history and Fraudlabs pro toolsets
- maxSteps limits how many tool calls the agent can take in a single run
- onStepFinish is a hook that prints intermediate steps for debugging
```typescript
let messages: AiMessageType[] = [];

console.log("Chat started! Type 'exit' or 'quit' to end.\n");

const rl = readline.createInterface({
  input: process.stdin,
  output: process.stdout,
  prompt: "> ",
});

rl.prompt();

rl.on("line", async (userInput: string) => {
  const trimmedInput = userInput.trim();

  if (["exit", "quit", "bye"].includes(trimmedInput.toLowerCase())) {
    console.log("\nGoodbye!");
    rl.close();
    process.exit(0);
  }

  if (!trimmedInput) {
    rl.prompt();
    return;
  }

  messages.push({
    id: crypto.randomUUID(),
    role: "user",
    content: trimmedInput,
  });

  console.log("\nAgent is thinking...\n");

  try {
    const response = await agent.generate(messages, {
      toolsets: {
        fraudlabs_pro: composioTools,
      },
      maxSteps: 8,
    });

    const { text } = response;

    if (text && text.trim().length > 0) {
      console.log(`Agent: ${text}\n`);
        messages.push({
          id: crypto.randomUUID(),
          role: "assistant",
          content: text,
        });
      }
    } catch (error) {
      console.error("\nError:", error);
    }

    rl.prompt();
  });

  rl.on("close", async () => {
    console.log("\nSession ended.");
    await mcpClient.disconnect();
    process.exit(0);
  });
}

main().catch((err) => {
  console.error("Fatal error:", err);
  process.exit(1);
});
```

## Frequently Asked Questions

### What are the differences in Tool Router MCP and Fraudlabs pro MCP?

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.

### Can I use Tool Router MCP with Mastra AI?

Yes, you can. Mastra AI 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.

### Can I manage the permissions and scopes for Fraudlabs pro while using Tool Router?

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.

### How safe is my data with Composio Tool Router?

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.
