What is Moltworker? {#what-is-moltworker}

Moltworker is an open-source middleware solution developed by Cloudflare that enables running Moltbot (formerly Clawdbot) personal AI agents on Cloudflare’s Developer Platform instead of dedicated hardware. Released in January 2026, moltworker represents a paradigm shift in how developers can deploy and manage AI agents.

The Moltbot Foundation

Before understanding moltworker, it’s essential to know what Moltbot is:

• Personal AI Assistant: Moltbot is an open-source AI agent designed to act as a personal assistant
• Multi-Platform Integration: Supports Telegram, Discord, Slack, and web-based control interfaces
• Extensible Architecture: Features a gateway architecture with persistent conversations and agent runtime
• Self-Hosted by Design: Originally required users to run it on their own hardware (Mac minis, Linux servers, etc.)

How Moltworker Transforms Deployment

Moltworker adapts Moltbot to run entirely on Cloudflare’s infrastructure through:

// Moltworker entrypoint example
import { getSandbox } from '@cloudflare/sandbox';

export default {
async fetch(request: Request, env: Env): Promise<Response> {
const sandbox = getSandbox(env.Sandbox, 'user-123');

// Moltbot runs inside this isolated sandbox
await sandbox.exec('moltbot-gateway start');

return Response.json({ status: 'running' });
}
};

💡 Key Insight Moltworker is not a fork of Moltbot—it’s a compatibility layer that allows the standard Moltbot runtime to operate in Cloudflare’s serverless environment.

Why Moltworker Matters: The Hardware Problem {#why-moltworker-matters}

The Mac Mini Rush of 2026

When Moltbot gained viral attention in January 2026, a peculiar phenomenon occurred: developers rushed to purchase Mac minis specifically to run their personal AI agents. This created several problems:

Challenge	Traditional Approach	Moltworker Solution
Initial Cost	$599+ for Mac mini	$5/month Workers plan
Maintenance	Manual updates, monitoring	Automatic platform updates
Uptime	Dependent on home internet	99.9%+ SLA on global network
Security	DIY firewall, VPN setup	Built-in Access, Zero Trust
Scaling	Buy more hardware	Automatic resource allocation
Power Consumption	24/7 electricity costs	Pay-per-use serverless model

The Cloudflare Advantage

Moltworker leverages Cloudflare’s Developer Platform, which has evolved to support complex applications:

• Node.js Compatibility: 98.5% of top 1,000 NPM packages now work natively in Workers
• Sandbox SDK: Secure isolated environments for running untrusted code
• Global Network: 300+ data centers ensure low-latency access worldwide
• Integrated Services: AI Gateway, R2 storage, Browser Rendering, and Zero Trust Access work seamlessly together

⚠️ Important Note Moltworker is currently a proof-of-concept, not an official Cloudflare product. It’s maintained as an open-source project to showcase platform capabilities.

Core Components Explained

1. Entrypoint Worker (API Router & Proxy)

The moltworker Worker serves multiple roles:

// Simplified moltworker routing logic
export default {
async fetch(request, env) {
const url = new URL(request.url);

// Admin UI routes
if (url.pathname.startsWith('/_admin/')) {
return handleAdminUI(request, env);
}

// CDP proxy for browser automation
if (url.pathname.startsWith('/cdp/')) {
return handleCDPProxy(request, env);
}

// WebSocket connection to Moltbot
if (url.pathname === '/ws') {
return handleWebSocket(request, env);
}

// Control UI
return handleControlUI(request, env);
}
};

Key Responsibilities:

• Route HTTP/WebSocket requests to appropriate handlers
• Proxy Chrome DevTools Protocol (CDP) commands to Browser Rendering
• Serve the administrative interface
• Validate authentication tokens and Access JWTs

2. Cloudflare Sandbox Container

The Sandbox SDK provides the isolated environment where Moltbot actually runs:

// Creating and managing the sandbox
const sandbox = getSandbox(env.Sandbox, userId);

// Install Moltbot in the container
await sandbox.exec('npm install -g moltbot');

// Mount R2 bucket for persistence
await sandbox.mountBucket(env.R2_BUCKET, '/root/.moltbot');

// Start the gateway process
const process = await sandbox.startProcess('moltbot-gateway', {
env: {
ANTHROPIC_API_KEY: env.ANTHROPIC_API_KEY,
GATEWAY_TOKEN: env.MOLTBOT_GATEWAY_TOKEN
}
});

Sandbox Features:

• Isolation: Each user gets their own secure container
• Filesystem Access: Full read/write capabilities within the container
• Process Management: Run background services like the Moltbot gateway
• Network Access: Controlled outbound connections to AI providers and chat platforms

3. AI Gateway Integration

Moltworker routes all AI model requests through Cloudflare AI Gateway:

# Configuration for AI Gateway
export ANTHROPIC_BASE_URL="https://gateway.ai.cloudflare.com/v1/{account_id}/{gateway_id}/anthropic"
export AI_GATEWAY_API_KEY="your-anthropic-key"

Benefits of AI Gateway:

• Cost Tracking: Monitor spending across all AI providers
• Request Analytics: Detailed logs of model usage patterns
• Caching: Reduce redundant API calls with intelligent caching
• Fallbacks: Automatic failover to alternative models/providers
• Unified Billing: Use Cloudflare credits instead of managing multiple provider accounts

4. R2 Persistent Storage

Moltworker implements a backup/restore pattern for data persistence:

// Backup process (runs every 5 minutes via cron)
async function backupToR2(sandbox, r2Bucket) {
// Tar the Moltbot config directory
await sandbox.exec('tar -czf /tmp/backup.tar.gz /root/.moltbot');

// Upload to R2
const backupData = await sandbox.readFile('/tmp/backup.tar.gz');
await r2Bucket.put('moltbot-backup.tar.gz', backupData);

console.log('Backup completed at', new Date().toISOString());
}

// Restore on container startup
async function restoreFromR2(sandbox, r2Bucket) {
const backup = await r2Bucket.get('moltbot-backup.tar.gz');
if (backup) {
await sandbox.writeFile('/tmp/restore.tar.gz', await backup.arrayBuffer());
await sandbox.exec('tar -xzf /tmp/restore.tar.gz -C /');
console.log('Restored from R2 backup');
}
}

What Gets Persisted:

• Paired device configurations
• Conversation history and context
• Custom skills and tools created by the agent
• User preferences and settings

5. Browser Rendering via CDP Proxy

One of moltworker’s most innovative features is the CDP (Chrome DevTools Protocol) proxy:

// CDP proxy implementation
async function handleCDPProxy(request, env) {
const url = new URL(request.url);

if (url.pathname === '/cdp/json/version') {
// Return browser version info from Browser Rendering
const browser = await puppeteer.launch(env.BROWSER);
return Response.json({ browserVersion: browser.version() });
}

if (url.pathname.startsWith('/cdp/devtools/browser/')) {
// Upgrade to WebSocket and proxy CDP commands
const browserId = url.pathname.split('/').pop();
return handleCDPWebSocket(request, env, browserId);
}
}

How It Works:

1. Moltbot inside the sandbox connects to localhost:9222 (standard CDP port)
2. Moltworker intercepts these connections and proxies them to the Worker
3. The Worker forwards CDP commands to Cloudflare Browser Rendering
4. Browser Rendering executes commands on a real Chromium instance
5. Responses flow back through the proxy to Moltbot

This architecture allows Moltbot to perform browser automation without running Chromium inside the container, saving resources and improving security.

6. Zero Trust Access Authentication

Moltworker uses Cloudflare Access to protect sensitive routes:

// Access JWT validation
async function validateAccessToken(request, env) {
const token = request.headers.get('Cf-Access-Jwt-Assertion');

if (!token) {
return { valid: false, error: 'No Access token' };
}

// Verify JWT signature and audience
const payload = await verifyJWT(token, {
audience: env.CF_ACCESS_AUD,
issuer: `https://${env.CF_ACCESS_TEAM_DOMAIN}/cdn-cgi/access/certs`
});

return { valid: true, user: payload.email };
}

Protected Routes:

• /_admin/* - Device management interface
• /api/* - Administrative API endpoints
• /debug/* - Diagnostic and logging endpoints

Data Flow Example: User Message to AI Response

Let’s trace a complete request through moltworker:

1. User sends message via Telegram to their paired bot
2. Telegram webhook hits the moltworker Worker endpoint
3. Worker validates the gateway token and device pairing status
4. Message forwarded to Moltbot gateway running in the Sandbox
5. Moltbot processes the message and determines it needs AI assistance
6. AI request sent through AI Gateway to Anthropic Claude
7. Claude response flows back through AI Gateway (logged for analytics)
8. Moltbot formats the response and sends it back to the Worker
9. Worker delivers the response to Telegram’s API
10. User receives the AI-generated message in their chat

Throughout this flow:

• All AI requests are logged in AI Gateway for cost tracking
• Conversation context is stored in R2 for persistence
• Access logs are recorded in Zero Trust for security auditing

How to Deploy Moltworker: Step-by-Step Guide {#deployment-guide}

Prerequisites

Before deploying moltworker, ensure you have:

• ✅ Cloudflare account with Workers Paid plan ($5/month)
• ✅ Anthropic API key (or plan to use AI Gateway Unified Billing)
• ✅ Node.js 18+ and npm installed locally
• ✅ Wrangler CLI installed (npm install -g wrangler)

Step 1: Clone and Install

# Clone the moltworker repository
git clone https://github.com/cloudflare/moltworker.git
cd moltworker

# Install dependencies
npm install

# Authenticate with Cloudflare
wrangler login

Step 2: Configure AI Provider

Choose between direct Anthropic access or AI Gateway:

Option A: Direct Anthropic Access

# Set your Anthropic API key
npx wrangler secret put ANTHROPIC_API_KEY
# Paste your key when prompted

Option B: AI Gateway (Recommended)

# Create an AI Gateway in the Cloudflare dashboard
# Then configure the secrets:

npx wrangler secret put AI_GATEWAY_API_KEY
# Enter your Anthropic key

npx wrangler secret put AI_GATEWAY_BASE_URL
# Enter: https://gateway.ai.cloudflare.com/v1/{account_id}/{gateway_id}/anthropic

💡 Pro Tip Using AI Gateway provides better observability and cost control. You can switch between providers without redeploying moltworker.

Step 3: Generate Gateway Token

# Generate a secure random token
export MOLTBOT_GATEWAY_TOKEN=$(openssl rand -base64 32 | tr -d '=+/' | head -c 32)

# Display and save this token - you'll need it to access the UI
echo "Your gateway token: $MOLTBOT_GATEWAY_TOKEN"

# Set it as a secret
echo "$MOLTBOT_GATEWAY_TOKEN" | npx wrangler secret put MOLTBOT_GATEWAY_TOKEN

⚠️ Critical: Save this token securely. You’ll need it to access the Control UI at https://your-worker.workers.dev/?token=YOUR_GATEWAY_TOKEN

Step 4: Deploy Moltworker

# Deploy to Cloudflare Workers
npm run deploy

# Output will show your worker URL:
# Published moltbot-sandbox (X.XX sec)
#   https://moltbot-sandbox.your-subdomain.workers.dev

Step 5: Configure Cloudflare Access

To use the admin UI, you must set up authentication:

Enable Access on workers.dev

1. Go to Workers & Pages dashboard
2. Select your deployed Worker (e.g., moltbot-sandbox)
3. Navigate to Settings → Domains & Routes
4. In the workers.dev row, click the menu (...) → Enable Cloudflare Access
5. Click Manage Cloudflare Access to configure authentication:

• Add your email to the allow list
• Or configure identity providers (Google, GitHub, etc.)

1. Copy the Application Audience (AUD) tag

Set Access Secrets

# Your Cloudflare Access team domain
npx wrangler secret put CF_ACCESS_TEAM_DOMAIN
# Enter: myteam.cloudflareaccess.com

# Application Audience tag from Access settings
npx wrangler secret put CF_ACCESS_AUD
# Paste the AUD value you copied

Redeploy

npm run deploy

Step 6: Enable R2 Persistent Storage (Recommended)

Without R2, your data is lost when the container restarts.

Create R2 API Token

1. Go to R2 → Overview in Cloudflare dashboard
2. Click Manage R2 API Tokens
3. Create token with Object Read & Write permissions
4. Select the moltbot-data bucket (auto-created on first deploy)
5. Copy Access Key ID and Secret Access Key

Configure R2 Secrets

# R2 credentials
npx wrangler secret put R2_ACCESS_KEY_ID
npx wrangler secret put R2_SECRET_ACCESS_KEY

# Your Cloudflare Account ID
npx wrangler secret put CF_ACCOUNT_ID
# Find this in dashboard: Click account menu → Copy Account ID

Redeploy

npm run deploy

Step 7: Pair Your First Device

1. Visit the admin UI: https://your-worker.workers.dev/_admin/
2. Authenticate via Cloudflare Access
3. Open the Control UI in a new tab: https://your-worker.workers.dev/?token=YOUR_GATEWAY_TOKEN
4. The Control UI will show "Waiting for pairing approval..."
5. Return to the admin UI and approve the pending device
6. Your Control UI is now connected!

⏱️ Note: The first request may take 1-2 minutes while the container starts. Subsequent requests are much faster.

Step 8: Optional Integrations

Add Telegram Bot

# Create a bot via @BotFather on Telegram
# Copy the bot token and set it:
npx wrangler secret put TELEGRAM_BOT_TOKEN
npm run deploy

Add Discord Bot

# Create a bot in Discord Developer Portal
# Copy the bot token and set it:
npx wrangler secret put DISCORD_BOT_TOKEN
npm run deploy

Add Slack Bot

# Create a Slack app with bot capabilities
# Copy both tokens and set them:
npx wrangler secret put SLACK_BOT_TOKEN
npx wrangler secret put SLACK_APP_TOKEN
npm run deploy

Enable Browser Automation

# Generate a secure secret for CDP authentication
npx wrangler secret put CDP_SECRET
# Enter a random string

# Set your worker's public URL
npx wrangler secret put WORKER_URL
# Enter: https://your-worker.workers.dev

npm run deploy

Security Considerations and Best Practices {#security-best-practices}

Multi-Layer Authentication Architecture

Moltworker implements defense-in-depth with three authentication layers:

Layer	Purpose	Protects Against
Gateway Token	Access to Control UI	Unauthorized UI access
Device Pairing	Per-device authorization	Rogue clients, stolen tokens
Cloudflare Access	Admin UI protection	Unauthorized administration

How They Work Together

graph TD
A[User Request] --> B{Has Gateway Token?}
B -->|No| C[Reject: 401 Unauthorized]
B -->|Yes| D{Device Paired?}
D -->|No| E[Show Pairing Pending]
D -->|Yes| F{Admin Route?}
F -->|No| G[Allow: Normal Operation]
F -->|Yes| H{Valid Access JWT?}
H -->|No| I[Redirect to Access Login]
H -->|Yes| J[Allow: Admin Access]

Critical Security Warnings

⚠️ Prompt Injection Vulnerability

Moltbot is susceptible to prompt injection attacks via:

• Email content (if email integration is enabled)
• Web pages visited by the browser automation
• Chat messages from untrusted sources

Mitigation: Only enable integrations you trust. Never connect moltworker to public email addresses or allow it to browse untrusted websites.

⚠️ Supply Chain Risk

As discussed on Hacker News, moltbot’s dependency chain and rapid development pose supply chain attack risks.

Mitigation:

• Pin specific versions in your deployment
• Review the closed PRs and issues before updating
• Consider forking for production use

⚠️ Data Privacy

While moltworker runs in isolated sandboxes, Cloudflare can technically access:

• All data passing through Workers
• Content stored in R2 buckets
• Logs and analytics data

Mitigation: Don’t use moltworker for sensitive data if you require zero-knowledge architecture. For maximum privacy, self-host Moltbot on your own hardware.

Best Practices for Secure Deployment

1. Token Management

# Generate cryptographically secure tokens
openssl rand -base64 32 | tr -d '=+/' | head -c 32

# Rotate tokens regularly (every 90 days)
npx wrangler secret put MOLTBOT_GATEWAY_TOKEN
npm run deploy

2. Access Policy Configuration

Configure strict Access policies in the Zero Trust dashboard:

# Example Access policy
Name: Moltworker Admin Access
Application Domain: moltbot-sandbox.your-subdomain.workers.dev
Paths:
- /_admin/*
- /api/*
- /debug/*
Policy:
- Include:
- Email: [email protected]
- Exclude:
- Everyone
Session Duration: 24 hours

3. Container Lifecycle Management

# For production: Keep container always alive
# (Default behavior, no action needed)

# For development/testing: Allow container to sleep
npx wrangler secret put SANDBOX_SLEEP_AFTER
# Enter: 1h (container sleeps after 1 hour of inactivity)

4. Monitoring and Alerting

Enable comprehensive logging:

# Enable debug routes (only in development)
npx wrangler secret put DEBUG_ROUTES
# Enter: true

Access debug endpoints:

• GET /debug/processes - List container processes
• GET /debug/logs?id=<process_id> - View process logs
• GET /debug/version - Check moltbot and container versions

5. Network Isolation

Moltworker automatically isolates:

• Each user’s sandbox from others
• Outbound connections to only approved destinations
• Inbound connections through the Worker proxy only

6. Secrets Rotation Schedule

Secret	Rotation Frequency	Impact
Gateway Token	Every 90 days	Requires re-pairing all devices
AI Provider Keys	Every 180 days	Transparent to users
R2 Access Keys	Every 180 days	Requires redeployment
CDP Secret	Every 90 days	Breaks browser automation until updated

Security Audit Checklist

Before deploying moltworker to production:

• All secrets are set via wrangler secret put (never in code)
• Cloudflare Access is enabled on all admin routes
• Gateway token is cryptographically random (32+ characters)
• Device pairing is enabled (not using DEV_MODE=true)
• R2 bucket has restricted access (not public)
• Only necessary chat integrations are enabled
• Email integration is disabled (high prompt injection risk)
• Debug routes are disabled in production
• Access logs are being monitored
• Backup strategy is in place for R2 data

Community Feedback and Concerns {#community-feedback}

The Hacker News discussion revealed significant community concerns about both Moltbot and moltworker:

Positive Reception

✅ Cloudflare’s Node.js Progress: Developers praised the 98.5% NPM package compatibility ✅ Sandbox SDK Utility: Many saw value in the Sandbox SDK beyond just moltworker ✅ Deployment Simplicity: Appreciated the reduction in setup complexity vs self-hosting ✅ Built-in Observability: AI Gateway analytics and Access logs were highlighted as valuable

Major Concerns

1. Astroturfing and Hype Cycle

"There is so much branding and ‘look at our success’ marketing that this project comes off as heavily astro-turfed."

Community members noted:

• Excessive social media promotion from non-technical accounts
• Comparison to crypto-era hype cycles
• Concerns about an eventual startup pivot or acquisition

Cloudflare’s Response: Moltworker is explicitly labeled as a proof-of-concept, not a product. The goal is showcasing platform capabilities, not monetizing moltbot.

2. Security Vulnerabilities

"Clawdbot/Moltbot looks to be a supply-chain attack waiting to happen."

Specific security issues raised:

• Prompt Injection: No protection against malicious prompts in emails/websites
• Supply Chain: Rapid development with low technical oversight
• Insecure Deployments: Many users exposing dashboards without authentication
• Email Integration Risk: Connecting to email creates attack vector

Mitigation Strategies:

• Moltworker enforces device pairing by default
• Cloudflare Access protects admin routes
• Sandbox isolation limits blast radius
• Documentation warns against email integration

3. Overhyped Capabilities

"Ultimately its a convenience wrapper that makes it easy to wire up Claude or ChatGPT to a chat platform like discord, but its claiming to be far more revolutionary."

Critics argued:

• Core functionality is just API wrappers
• Similar tools exist (e.g., afk-code - 2-minute setup)
• The "agent" label is misleading marketing

Counterpoint: While the core is API integration, the value lies in:

• Persistent memory and context
• Self-modifying capabilities (agents creating their own tools)
• Multi-platform gateway architecture
• Production-ready deployment on global infrastructure

4. Data Privacy Concerns

"All home/local integrations are gone. Data needs to be stored in the cloud. No thanks."

Valid concerns about moltworker specifically:

• Cloudflare can access all data passing through Workers
• R2 storage is not zero-knowledge
• Loss of local network integrations (smart home, NAS, etc.)

When This Matters:

• Handling sensitive personal data
• Compliance requirements (HIPAA, GDPR with strict data residency)
• Desire for complete control over infrastructure

When It Doesn’t:

• Using public AI providers anyway (Anthropic already sees your data)
• Trusting Cloudflare’s security practices
• Prioritizing convenience over absolute privacy

5. Technical Skepticism

"Just look at the closed PRs of their project. General technical knowledge is so low it’s insane."

Community members reviewed moltbot’s GitHub and found:

• Low-quality contributions
• Security vulnerabilities in closed PRs
• Lack of code review rigor

Important Context: Moltbot is a rapidly evolving open-source project. Moltworker adapts it but doesn’t control its development. Users should:

• Review moltbot’s security posture before deploying
• Consider forking for production use
• Monitor the project’s issue tracker

Balanced Perspective

The community consensus seems to be:

✅ Moltworker as a Platform Demo: Excellent showcase of Cloudflare’s capabilities ✅ Sandbox SDK Value: Useful beyond just moltbot ⚠️ Moltbot Maturity: Treat as experimental, not production-ready ⚠️ Security Posture: Requires careful configuration and ongoing monitoring ❌ Hype vs Reality: Marketing outpaces technical substance

R2 Storage Not Working

Problem: "Data lost after container restart" or "R2 not mounting"

Solutions:

# 1. Verify all three R2 secrets are set
npx wrangler secret list | grep R2

# Should show:
# - R2_ACCESS_KEY_ID
# - R2_SECRET_ACCESS_KEY
# - CF_ACCOUNT_ID

# 2. Check R2 bucket exists
npx wrangler r2 bucket list

# Should show: moltbot-data

# 3. Test R2 access manually
npx wrangler r2 object get moltbot-data/moltbot-backup.tar.gz --file test.tar.gz

# 4. Trigger manual backup from admin UI
# Visit: https://your-worker.workers.dev/_admin/
# Click "Backup Now" button

Note: R2 mounting only works in production, not with wrangler dev.

Cloudflare Access Issues

Problem: "Access denied on admin routes" or "Infinite redirect loop"

Solutions:

# 1. Verify Access secrets are set
npx wrangler secret list | grep CF_ACCESS

# Should show:
# - CF_ACCESS_TEAM_DOMAIN

# Visit: https://your-worker.workers.dev/debug/logs?id=<process_id>

WebSocket Connection Failures

Problem: "WebSocket connection failed" or "Control UI disconnects"

Solutions:

# 1. Check if using wrangler dev (known limitation)
# WebSocket proxying through sandbox has issues in local dev
# Deploy to Cloudflare for full functionality

# 2. Verify gateway token in WebSocket URL
# Should be: wss://your-worker.workers.dev/ws?token=YOUR_GATEWAY_TOKEN

# 3. Check browser console for errors
# Look for CORS or authentication issues

# 4. Test WebSocket endpoint directly
npm install -g wscat
wscat -c "wss://your-worker.workers.dev/ws?token=YOUR_GATEWAY_TOKEN"

Browser Automation Issues

Problem: "CDP connection failed" or "Browser skill not working"

Solutions:

# 1. Verify CDP secrets are set
npx wrangler secret list | grep CDP

# Should show:
# - CDP_SECRET
# - WORKER_URL

-H "CDP_SECRET: your-secret"

# Should return browser version info

# 3. Check Browser Rendering is enabled
# Visit: https://dash.cloudflare.com/?to=/:account/workers/browser-rendering

# 4. Verify browser skill is installed in container
# Visit: https://your-worker.workers.dev/debug/processes
# Look for browser-related processes

Performance Issues

Problem: "Slow responses" or "Timeouts"

Solutions:

# 1. Check AI Gateway analytics
# Visit: https://dash.cloudflare.com/?to=/:account/ai/ai-gateway
# Look for slow provider responses

# 2. Configure container to never sleep
npx wrangler secret put SANDBOX_SLEEP_AFTER
# Enter: never

# 3. Enable caching in AI Gateway
# In AI Gateway settings:
# Enable "Cache responses" with appropriate TTL

# 4. Monitor cold start times
npx wrangler tail --format pretty

# Look for "Container starting" messages
# First request after sleep takes 60-120 seconds

Configuration Not Applying

Problem: "Config changes not working" or "Old settings persist"

Solutions:

# 1. Bust the Docker build cache
# Edit Dockerfile and change the cache bust comment:
# Build cache bust: 2026-01-30-v2

# 2. Force rebuild and redeploy
npm run deploy

# 3. Restart the gateway process
# Visit: https://your-worker.workers.dev/_admin/
# Click "Restart Gateway" button

# 4. Clear R2 backup and start fresh
npx wrangler r2 object delete moltbot-data/moltbot-backup.tar.gz
# Then restart the container

FAQ {#faq}

Q: Is moltworker production-ready?

A: No. Moltworker is explicitly labeled as a proof-of-concept by Cloudflare. It demonstrates platform capabilities but is not an officially supported product. For production use:

• Thoroughly review the security considerations
• Fork the repository and maintain your own version
• Implement additional monitoring and alerting
• Consider self-hosting Moltbot if you need guaranteed support

Q: How much does moltworker cost to run?

A: Typical monthly costs:

• Workers Paid Plan: $5/month (required)
• R2 Storage: $0.75/month (50GB storage + operations)
• Browser Rendering: $5/month (1M requests, $5/million after)
• AI Gateway: Free (no additional cost)
• Cloudflare Access: Free (up to 50 users)

Total: $10-15/month for typical usage

Q: Can I use moltworker with OpenAI instead of Anthropic?

A: Yes. Moltbot supports multiple AI providers:

# Set OpenAI API key
npx wrangler secret put OPENAI_API_KEY

# Or use AI Gateway with OpenAI provider
npx wrangler secret put AI_GATEWAY_API_KEY
npx wrangler secret put AI_GATEWAY_BASE_URL
# Enter: https://gateway.ai.cloudflare.com/v1/{account_id}/{gateway_id}/openai

AI Gateway makes it easy to switch between providers without code changes.

Q: How does moltworker handle data privacy?

A: Data privacy considerations:

• Cloudflare Access: Cloudflare can access all data passing through Workers and stored in R2
• AI Providers: Your conversations are sent to Anthropic/OpenAI (per their privacy policies)
• Encryption: Data in transit is encrypted (TLS), but Cloudflare can decrypt it
• Zero-Knowledge: Not possible with moltworker architecture

For maximum privacy, self-host Moltbot on your own hardware.

Q: Can I run moltworker locally for development?

A: Yes, with limitations:

# Create .dev.vars file
cat > .dev.vars << EOF
DEV_MODE=true
DEBUG_ROUTES=true
ANTHROPIC_API_KEY=your-key
EOF

# Run locally
npm run dev

Limitations:

• WebSocket connections may not work reliably
• R2 mounting is not available in local dev
• Sandbox behavior differs from production

For full functionality, deploy to Cloudflare.

Q: What happens if Cloudflare has an outage?

A: During a Cloudflare outage:

• Your moltworker instance will be unavailable
• No data is lost (R2 backups persist)
• Once service resumes, your agent automatically recovers
• Conversation history and paired devices remain intact

Cloudflare’s uptime is typically 99.9%+, but for critical applications, consider:

• Multi-cloud deployment (self-hosted backup)
• Monitoring and alerting for outages
• Documented recovery procedures

Q: Can I customize the Moltbot runtime in moltworker?

A: Yes, but with constraints:

• Custom Skills: Add skills to the container via Dockerfile modifications
• Environment Variables: Configure via wrangler secrets
• System Packages: Install via Dockerfile (apt-get, npm, etc.)
• Limitations: Cannot modify the underlying Workers Runtime or Sandbox SDK

Example Dockerfile customization:

# Add custom skill
COPY my-custom-skill /root/clawd/skills/my-custom-skill

# Install additional packages
RUN apt-get update && apt-get install -y \
python3-pip \
ffmpeg

# Install Python dependencies
RUN pip3 install requests beautifulsoup4

Q: How do I migrate from self-hosted Moltbot to moltworker?

A: Migration steps:

Export existing data:

# On your self-hosted machine
tar -czf moltbot-backup.tar.gz ~/.moltbot

Deploy moltworker (follow deployment guide above) 1.

Upload backup to R2:

npx wrangler r2 object put moltbot-data/moltbot-backup.tar.gz \
--file moltbot-backup.tar.gz

Restart container to trigger restore:

# Visit admin UI and click "Restart Gateway"

Re-pair devices if device IDs changed 1.

Test thoroughly before decommissioning self-hosted instance

Q: Is moltworker vulnerable to prompt injection attacks?

A: Yes. Both Moltbot and moltworker are susceptible to prompt injection via:

• Email content (if email integration enabled)
• Web pages visited by browser automation
• Chat messages from untrusted sources

Mitigation strategies:

• Never enable email integration
• Only browse trusted websites
• Use device pairing to restrict access
• Monitor AI Gateway logs for suspicious activity
• Consider implementing prompt filtering (custom middleware)

There is currently no foolproof defense against prompt injection in LLM-based agents.

Q: Can I use moltworker for commercial purposes?

A: Check the licenses:

• Moltworker: Cloudflare’s repository license (likely permissive, verify on GitHub)
• Moltbot: Check moltbot’s license on their GitHub repository
• Cloudflare Services: Review Cloudflare’s Terms of Service for commercial use

For commercial deployments:

• Consult with legal counsel
• Consider forking and maintaining your own version
• Implement proper monitoring and SLAs
• Ensure compliance with data protection regulations

Q: How do I contribute to moltworker?

A: Moltworker is open-source:

1. Fork the repository: https://github.com/cloudflare/moltworker
2. Create a feature branch: git checkout -b feature/my-improvement
3. Make your changes and test thoroughly
4. Submit a pull request with detailed description
5. Engage with maintainers on GitHub issues

Cloudflare has indicated they’ll monitor the repository for a while but it’s not an officially supported product.

Q: What’s the future of moltworker?

A: As of January 2026, moltworker is a proof-of-concept. Possible futures:

• Community Maintenance: Becomes a community-driven project
• Official Product: Cloudflare productizes it (unlikely based on current statements)
• Upstream Contribution: Features merged into official Moltbot
• Deprecation: Project becomes unmaintained as Moltbot evolves

For production use, plan for the possibility of maintaining your own fork.

Conclusion

Moltworker represents an innovative approach to deploying AI agents, leveraging Cloudflare’s Developer Platform to eliminate hardware requirements while providing enterprise-grade security and observability. However, it’s essential to approach it with realistic expectations:

Moltworker Excels At:

• Demonstrating Cloudflare’s platform capabilities
• Reducing deployment complexity vs self-hosting
• Providing integrated observability and security
• Enabling rapid experimentation with AI agents

Moltworker Falls Short On:

• Production-readiness and official support
• Absolute data privacy (Cloudflare can access data)
• Local network integrations (smart home, NAS, etc.)
• Protection against prompt injection attacks

Key Takeaway: Moltworker is an excellent proof-of-concept and learning tool, but requires careful security configuration and realistic expectations about its maturity. For sensitive data or mission-critical applications, traditional self-hosting may be more appropriate.

Next Steps

1. Experiment: Deploy moltworker in a test environment
2. Evaluate: Assess if it meets your security and privacy requirements
3. Monitor: Watch the GitHub repository for updates and security advisories
4. Contribute: Help improve moltworker through code contributions or feedback
5. Decide: Choose between moltworker, self-hosting, or a hybrid approach based on your needs
