Cloudflare Workers Deployment

Deploy OpenClaw on Cloudflare’s edge network using the moltworker container runtime.

Overview

Item	Value
Repository	github.com/strataga/moltworker
Monthly Cost	~$5 (Workers) + API costs
Setup Time	5-10 minutes
Control UI	`/_admin/`

We recommend the strataga/moltworker fork instead of the official cloudflare/moltworker. The fork adds public webhook routes required for Slack and Discord integrations.

Prerequisites

Cloudflare account with Workers Paid plan ($5/mo)
Anthropic API key
Node.js 18+ installed locally
Wrangler CLI (npm install -g wrangler)

Deployment Steps

Clone the Repository


git clone https://github.com/strataga/moltworker.git
cd moltworker
npm install

Configure Worker Name

Edit wrangler.jsonc to set your worker name:


{
  "name": "your-worker-name",  // Change this
  // ... rest of config
}

Build and Deploy


npm run build
npx wrangler deploy

Configure Secrets

Required secrets:


npx wrangler secret put ANTHROPIC_API_KEY
npx wrangler secret put MOLTBOT_GATEWAY_TOKEN
npx wrangler secret put CF_ACCESS_TEAM_DOMAIN
npx wrangler secret put CF_ACCESS_AUD

Set Up Cloudflare Access

Go to Zero Trust Dashboard
Create an Access Application for your worker
Set path to /_admin/* (NOT /)
Configure authentication (email OTP is simplest)
Note the Application Audience (AUD) tag
Add the AUD to secrets: CF_ACCESS_AUD

Messaging Integrations

Slack (Recommended)

Slack works reliably with moltworker. Use HTTP Mode (not Socket Mode).

Create Slack App

Go to api.slack.com/apps
Create a new app from scratch
Select your workspace

Enable Event Subscriptions

Request URL: https://YOUR-WORKER.workers.dev/slack/events
Subscribe to bot events:
- message.channels
- message.im
- app_mention

Enable Interactivity

Request URL: https://YOUR-WORKER.workers.dev/slack/interactions

Add OAuth Scopes

Under “OAuth & Permissions”, add:

chat:write
channels:history
im:history
users:read

Install and Configure

Install app to workspace
Copy Bot Token (starts with xoxb-)
Add to Worker secrets:


npx wrangler secret put SLACK_BOT_TOKEN

Discord

Create Discord Application

Go to discord.com/developers
Create a new application

Configure Interactions Endpoint

URL: https://YOUR-WORKER.workers.dev/discord/interactions

Add Bot to Server

Generate OAuth2 URL with bot scope
Select required permissions
Authorize in your server

Add Secret


npx wrangler secret put DISCORD_BOT_TOKEN

Telegram (Limited Support)

Telegram has fundamental limitations on Cloudflare Workers due to container hibernation. For reliable Telegram support, use VPS deployment.

Why Telegram is unreliable:

OpenClaw uses long-polling by default for Telegram
Cloudflare containers hibernate when idle
Hibernated containers can’t receive poll responses
New messages can’t wake the container

If you must use Telegram:

Set the webhook manually:


curl -X POST "https://api.telegram.org/bot<TOKEN>/setWebhook" \
  -H "Content-Type: application/json" \
  -d '{"url": "https://YOUR-WORKER.workers.dev/telegram-webhook"}'

Do NOT set TELEGRAM_DM_POLICY - it causes gateway crashes.
