How to solve MTCaptcha with Python

TL;DR

This guide demonstrates how to solve MTCaptcha programmatically using Python and the CapSolver API. With minimal dependencies and a proxyless configuration, developers can quickly integrate automated MTCaptcha solving into data collection, testing, or workflow automation scenarios. The article walks through prerequisites, package installation, a complete Python example, and key configuration points to help you get started efficiently.

Introduction

MTCaptcha is increasingly adopted by websites as a lightweight, privacy-focused alternative to traditional CAPTCHA systems. While effective at distinguishing human users from automated traffic, it can interrupt legitimate automation workflows such as web testing, data collection, and backend integrations.

In this tutorial, we explain how to solve MTCaptcha using Python with CapSolver’s API. The approach is straightforward, does not require a proxy by default, and is suitable for developers who need a reliable, scalable solution. By following the steps below, you can integrate MTCaptcha handling into your Python projects with minimal setup.

⚙️ Prerequisites

• A working proxy (OPTIONAL)
• Python installed
• Capsolver API key

🤖 Step 1: Install Necessary Packages

Execute the following commands to install the required packages:

pip install capsolver

👨‍💻 Python Code for solve MTCaptcha without proxy

Here's a Python sample script to accomplish the task:

import capsolver

capsolver.api_key = "your pay per usage key"
PAGE_URL = "websiteURL"
PAGE_KEY = "website site key"

def solver_mtcaptcha(url,key):
    solution = capsolver.solve({
        "type": "MTCaptchaTaskProxyless",
        "websiteURL": url,
        "websitePublicKey":key
    })
    return solution


def main():

    print("Solving MTCaptcha...")
    solution = solver_mtcaptcha(PAGE_URL, PAGE_KEY)
    print("Solution: ", solution)

if __name__ == "__main__":
    main()

⚠️ Change these variables

• PROXY: Update with your proxy details. The format should be http://username:password@ip:port.
• capsolver.api_key: Obtain your API key from the Capsolver Dashboard.
• PAGE_URL: Replace with the URL of the website for which you wish to solve mtcaptcha
• PAGE_KEY: Replace with the KEY of the website

This method is well-suited for automation workflows that prioritize speed, stability, and ease of integration.

As websites continue to evolve their verification mechanisms, using a dedicated CAPTCHA-solving service allows teams to focus on core product logic rather than constant adaptation. With the example provided in this guide, you can quickly extend or customize the implementation to fit your specific use case.

FAQs

1. What is MTCaptcha?

MTCaptcha is a CAPTCHA solution designed to reduce user friction while maintaining security. It emphasizes privacy and typically avoids extensive user tracking compared to some other CAPTCHA providers.

2. Do I need a proxy to solve MTCaptcha with this method?

No. The provided example uses a proxyless task type. A proxy is optional and may be required only in specific network or geographic scenarios.

3. Where can I find the MTCaptcha site key?

The site key (public key) is usually embedded in the target webpage’s source code or JavaScript configuration where MTCaptcha is initialized.

4. Is this approach suitable for large-scale automation?

Yes. CapSolver is designed to support high-throughput use cases, making it suitable for production environments that require consistent and scalable CAPTCHA handling.
