Today, we’re exploring Molt Worker, a middleware solution designed to run Maltbot (the tool formerly known as Clawbot) directly inside Cloudflare’s sandboxed SDK. Security is a significant concern for many when it comes to how AI agents connect with the outside world, so this article will put Molt Worker to the test to see how it performs and how difficult it is to implement.
The Security Problem with Traditional Setups
There are a few well-known security issues with Clawbot. The vulnerabilities are serious.
First, if you’re running the agent on a Virtual Private Server (VPS), a compromise of that server means an attacker gains full access to your Clawbot instance. That’s a scenario to avoid at all costs.
Another significant risk involves prompt injection. Attackers could potentially email an account connected to your Clawbot and use carefully crafted prompts to hijack its functionality. Both of these are critical security flaws that demand a better solution.
Enter Molt Worker: The Cloudflare Solution
Instead of a self-hosted approach, we will try a method using Molt Worker on Cloudflare. This promises a much more secure environment for running our AI assistant.
The setup process is detailed, and it begins with the official GitHub repository.

One of the first requirements is to have a Cloudflare Workers paid plan, which is a necessary step to get started. After upgrading to the appropriate plan, the real work can begin.
Step-by-Step Installation Guide
The setup is technical, but by following these steps, you can create a secure, sandboxed environment for your AI agent.
1. Clone the Repository
First, open a new terminal and clone the Molt Worker repository to your local machine.
git clone <repository_url>
2. Set Up Your API Key
Next, you need to configure your Anthropic API key. You can generate a new key from the console.anthropic.com dashboard under the “API Keys” section.
Once you have your key, you must securely add it to your Cloudflare environment using the Wrangler CLI.
npx wrangler secret put ANTHROPIC_API_KEY
After running this command, your browser will open a confirmation page to authorize the action. You must click “Allow” to proceed.
3. Install Docker
Molt Worker runs within a Docker container, so you must have Docker installed and running on your machine. The installation process is straightforward for most operating systems.
4. Deploy to Cloudflare
With the prerequisites in place, you can deploy the application.
npm run deploy
Note: The initial deployment can be slow. It involves pushing the Docker container layers to Cloudflare’s infrastructure and can take between 3 to 5 minutes. Be patient and let the process complete.
5. Configure Cloudflare Services
While the deployment is running, a few more configurations are needed within your Cloudflare dashboard.
- Enable R2 Storage: Molt Worker requires R2 storage. You can enable this service, which includes a generous free tier of 10GB per month.
- Set Up a
workers.devSubdomain: Navigate to “Workers & Pages” in your Cloudflare sidebar. Under the “Compute and AI” section, ensure you have aworkers.devsubdomain configured. This is where your worker will be hosted. - Enable Cloudflare Access: For enhanced security, go to the settings for your
workers.devsubdomain and toggle on “Cloudflare Access.” This is a critical step for securing your admin UI. You will get an audience key that you may need to plug back into your configuration.
Once deployed, you will have a Molt Worker sandbox set up and visible in the “Workers & Pages” section of your Cloudflare dashboard.
Why is Cloudflare a More Secure Option?
You might be wondering why using Cloudflare is better than hosting locally or on a standard VPS. Let’s use an analogy.
Think of a self-hosted AI assistant as a personal assistant living in your house. You are solely responsible for locking the doors, paying for electricity, and ensuring the entire property is secure.
Molt Worker on Cloudflare is like having that same assistant work from a massive, high-security office building that Cloudflare owns and operates. You just pay the rent. The security is inherently better for several reasons:
- Zero Trust Access: Cloudflare’s model ensures that no user or device is trusted by default, adding a powerful layer of security.
- Isolated Sandboxes: Each task runs in its own isolated sandbox. If something goes wrong in one task, the issue is contained and cannot spread to the rest of the system. In a traditional setup, everything often shares the same space, increasing risk.
- No Keys Lying Around: Self-hosted Clawbot setups often store API keys in plain-text configuration files, which is a major security risk. Cloudflare’s secret management handles this securely.
- Enterprise-Grade Security: Cloudflare’s entire business is built on security, protecting a massive portion of the internet. A personal computer or a basic VPS simply cannot compete with that level of protection.
Accessing Your Secure Admin UI
After a successful deployment, you won’t be able to access the admin panel directly. The page will first require you to enter your email address. A secure login code will be sent to that email, which you must use to gain access.
This two-factor authentication ensures that only authorized users can log in. Once you’re in, you’ll see the Molt Worker dashboard. The containerized environment keeps everything siloed and secure.
After logging in, you can see the health status of the service and begin using your sandboxed Clawbot instance.
The Final Verdict: Difficult but Worthwhile
To be perfectly clear, setting up Molt Worker is not a simple task. It was one of the more challenging setup processes for this kind of tool. If you are looking for an easy, one-click installation, this is not it.
However, if security is your top priority, Molt Worker is arguably one of the most robust and secure ways to run your AI assistant.
The system provides multiple layers of protection:
- Cloudflare’s Network: The entire service is shielded by Cloudflare’s world-class security infrastructure.
- Email-Based Login: Access is gated by a secure code sent to an authorized email address.
- Device Pairing Approval: From the admin panel, you can see which devices are paired and must manually approve any new device before it can connect.
Everything is sandboxed with Docker, it isn’t hosted locally or on an easily compromised VPS, and access is strictly controlled. For those willing to tackle the technical setup, Molt Worker offers a powerful and secure way to operate an AI assistant.
