Easy API - SocketClient - Embedded runtime - Plugins - MCP - Support

What this is

@open-wa/wa-automate is a Node.js toolkit for WhatsApp Web automation. You can make a local API, bot backend, webhook source, plugin host, or MCP server.

This repository is the v5 monorepo. Its packages share the stable 5.0.0 release and use separate modules for the runtime, drivers, API, and integrations.

Need a WhatsApp API running quickly? Start with Easy API. Want the browser/runtime inside your own app? Use the embedded runtime. Building integrations, proxying sessions, or exposing WhatsApp to an AI agent? Those surfaces are in this repo too.

What can you build?

• customer support inboxes that sync WhatsApp into your own tools
• order, booking, and delivery notifications from internal systems
• bots that react to messages, group activity, and runtime events
• webhook bridges for CRMs, helpdesks, automations, and low-code tools
• multi-session automations with named accounts and isolated consumers
• AI-agent workflows through the built-in Model Context Protocol server

The short version

You can use this project in a few practical ways:

• run a ready-made API with the CLI
• connect another app to that runtime
• embed the runtime directly in your own Node.js code
• add integrations and plugins

Quick start: Easy API

Want to convert a WhatsApp account into an API with the least ceremony? Run the CLI:

npx @open-wa/wa-automate@latest --port 8080

That starts an Easy API instance, launches the first-run authentication flow, and exposes interactive docs for the live session.

Use an explicit version in deployments that need repeatable installs.

For first login, the runtime will ask you to authenticate. Depending on your setup, either:

• scan the QR code the runtime prints, or
• use link-code login if that fits your setup better

http://localhost:8080/api-docs/

That page is your first proof of life: the session is up, the API is reachable, and the method surface is discoverable.

Other useful generated artifacts:

http://localhost:8080/meta/swagger.json
http://localhost:8080/meta/postman.json

Useful first commands:

# choose a port
npx @open-wa/wa-automate@latest --port 8080
provide your own API key
npx @open-wa/wa-automate@latest --port 8080 --api-key "your-secure-key"
run a named session
npx @open-wa/wa-automate@latest --session-id sales --port 8081

Good defaults for a first real session:

• set a sessionId early if you might run more than one account
• protect the API with an --api-key before exposing it outside your machine
• keep business logic in your own app and let open-wa own the WhatsApp runtime

If you prefer Docker:

docker run -p 8080:8080 --init openwa/wa-automate

Docker notes:

• this is best for local testing or a disposable first run unless you also plan session persistence properly
• use --init so the init process removes zombie processes
• you can pin the library version with W_A_V, for example -e W_A_V=4.42.1

Simple automation: SocketClient

Building a bot, worker, or app integration? Keep the WhatsApp runtime in Easy API and let your Node.js app act as a clean remote consumer.

Start the runtime:

npx @open-wa/wa-automate@latest --port 8080 --api-key "your-secure-key"

Install the remote consumer in your app:

npm install @open-wa/socket-client

Keep the Easy API process running. Your app is a remote consumer, not the runtime host.

Then connect from your app:

import { SocketClient } from '@open-wa/socket-client';
async function start() {
  const client = await SocketClient.connect('http://localhost:8080', 'your-secure-key');
client.onMessage(async (message) => {
    if (message.body === 'Hi') {
      await client.sendText(message.from, '👋 Hello!');
    }
  });
}
start().catch(console.error);

Why this path is good for most builders:

• open-wa owns the browser automation runtime
• your app stays small and focused on automation logic
• the current v5 runtime uses HTTP RPC for commands and Server-Sent Events for runtime events behind the compatibility client

Deep integration: embedded runtime

If Easy API is the hosted engine, embedded runtime is the cockpit. Use it when your app needs to own browser selection, lifecycle, and runtime behavior directly.

The v5 public contract exposes createClient from @open-wa/core through @open-wa/wa-automate.

This path is lower-level than Easy API + SocketClient. Use it when runtime ownership matters more than the quickest working bot.

npm install @open-wa/wa-automate @open-wa/driver-puppeteer

import { createClient } from '@open-wa/wa-automate';
import { PuppeteerDriver } from '@open-wa/driver-puppeteer';
async function start() {
  const client = await createClient({
    sessionId: 'sales',
    driver: new PuppeteerDriver(),
    headless: true,
  });
client.onMessage(async (message) => {
    if (message.body === 'Hi') {
      await client.sendText(message.from, '👋 Hello!');
    }
  });
}
start().catch(console.error);

Important v5 reality:

• the repo’s current public contract centers on createClient
• maintainers are still reorganizing some older v4 docs
• pluggable browser drivers are part of the architecture

• @open-wa/driver-puppeteer
• @open-wa/driver-playwright
• @open-wa/driver-lightpanda

Configuration and CLI

Common config fields documented in the repo’s current config schema and docs include:

• sessionId
• headless
• useChrome / executablePath
• qrTimeout / authTimeout
• licenseKey
• linkCode
• plugins
• pluginConfig

--port 8080
--api-key "your-secure-key"
--session-id sales
--config ./wa.config.mjs
--pm2
--license-key "YOUR-LICENSE-KEY"

Some older docs and examples still mention additional legacy or transitional flags. For v5 onboarding, prefer the smaller set above unless you have verified the exact flag against the version you are running.

For contributors to this monorepo, the repo currently declares:

• Node.js >=22.21.1
• pnpm 11.15.1

pnpm install
pnpm build

Plugins and integrations

This repo is no longer just a single package. It includes a plugin/integration surface for extending the runtime.

Want to build one? Start with the plugin authoring guide (@open-wa/plugin-sdk).

Relevant packages in this repo:

• @open-wa/plugin-sdk
• @open-wa/integration-webhook
• @open-wa/integration-chatwoot
• @open-wa/integration-s3
• @open-wa/integration-cloudflare
• @open-wa/node-red

Loading plugins

The current config schema supports plugin references as npm package names or file paths:

plugins: [
  '@open-wa/integration-chatwoot',
  '@open-wa/integration-webhook',
  './my-local-plugin'
],
pluginConfig: {
  webhook: {
    // plugin-specific config
  }
}

If you want to share a bot or plugin

The safest documented path today is:

1. build it as an npm package or local package
2. expose it through the plugin SDK
3. tell users which plugins and pluginConfig entries they need

• ./integrations/webhook
• ./integrations/chatwoot
• ./integrations/cloudflare

• a public plugin marketplace
• a formal plugin discovery registry for community downloads

Built-in integration examples

• Webhook: push events into your own service
• Chatwoot: connect open-wa to Chatwoot for bidirectional message handling
• Cloudflare Session Proxy: remote session access without opening public ports
• Node-RED: low-code visual automation on top of Easy API

Cloudflare Session Proxy

If you want remote access without exposing local ports, this repo ships @open-wa/cf-proxy.

High-level flow:

1. deploy the Worker to your Cloudflare account
2. attach your session to that proxy as the upstream
3. connect consumers through the proxy URL

import { SocketClient } from '@open-wa/socket-client';
const client = await SocketClient.connect(
  'cf-proxy://open-wa-proxy.account.workers.dev?sessionId=my-session&token=CONSUMER_TOKEN'
);

This is the cleanest path if you want remote access but do not want to invent your own transport bridge.

AI-agent integration (MCP)

If your goal is to let an AI agent interact with WhatsApp, the cleanest surface is the built-in Model Context Protocol server.

MCP exposes each Easy API method as a tool. AI agents such as Claude, Cursor, and Windsurf can call these tools directly.

Quick start

Create wa.config.mjs:

export default {
  apiKey: process.env.WA_API_KEY,
  port: 8080,
  mcp: {
    enabled: true,
    path: '/mcp',
    exposeToolsMeta: true,
  },
};

Then start the v5 Easy API from the same directory:

WA_API_KEY="your-secure-key" npx @open-wa/wa-automate@latest --config ./wa.config.mjs

Then point your MCP client at:

http://localhost:8080/mcp

Claude Desktop

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "open-wa": {
      "url": "http://localhost:8080/mcp",
      "headers": {
        "X-API-Key": "your-secure-key"
      }
    }
  }
}

Cursor / Windsurf

Add a new MCP server with the URL http://localhost:8080/mcp and include X-API-Key in headers.

How it works

• Uses the Streamable HTTP transport (single endpoint, no separate SSE/messages paths)
• The schema registry generates the same tools as the HTTP API
• API key necessary on every request (same key as Easy API)
• The runtime blocks tools until the session connects
• Dashboard: shows connection status, configuration copy-paste snippets (Claude/Cursor), and live tool details at http://localhost:8080/dashboard/mcp

Configuration contract

{
  apiKey: process.env.WA_API_KEY,
  mcp: {
    enabled: true,
    path: '/mcp',
    exposeToolsMeta: true,
  },
}

The current v5 source does not parse --mcp. Enable MCP through wa.config.* as shown above.

Security boundary

MCP is an Easy API-only feature. It is not available through createClient(). The API key is mandatory — MCP refuses to start without one. Discovery (tool listing) and execution require authentication.

Without MCP

If you prefer HTTP, give your agent the Easy API docs surface instead:

• http://localhost:8080/api-docs/
• http://localhost:8080/meta/swagger.json
• http://localhost:8080/meta/postman.json

Migrating from v4 to v5

The npm latest tag now selects v5. Pin v4 explicitly while migrating an existing application:

npx @open-wa/[email protected]

The v5 runtime has a different public surface, so update existing integrations deliberately:

• start with Easy API and confirm http://localhost:8080/api-docs/ works
• test named sessions, auth, webhooks, and generated schemas in a separate environment
• prefer SocketClient for remote consumers instead of embedding browser/runtime work everywhere
• use createClient only when you need direct runtime ownership
• replace old v4 examples and flags with the v5 config and CLI options documented here
