WeChat

Connect CowAgent to your personal WeChat — scan to log in, no public IP required. Supports text, image, voice, file, and video messages in 1-on-1 chats. Backed by WeChat's official API; safe to use. After connecting, a bot assistant is added to your conversation list without affecting normal account usage.

1. Setup and run

Option A: Web console

Start CowAgent and open the Web console (local URL: http://127.0.0.1:9899/). Go to the Channels tab, click Connect Channel, select WeChat, and follow the prompts to scan in.

Option B: Config file

Set channel_type to weixin in config.json:

{
  "channel_type": "weixin"
}

After starting CowAgent, a QR code is displayed in the terminal. Scan it with WeChat to complete login.

2. Usage

Once authorized, the integration completes and you can start chatting. A bot assistant is created in your WeChat conversation list, leaving normal account usage unaffected.

You can find the bot at any time by searching for "微信ClawBot". You may also rename it, change its avatar, pin it to the top of your conversation list, and so on.

3. Login

QR code login

On first startup, a QR code appears in the terminal (valid for around 2 minutes). Scan it with WeChat and confirm on your phone to log in.

• The QR code refreshes automatically when it expires
• The qrcode dependency is already included in requirements.txt, so the QR code renders directly in the terminal after install

Credential persistence

After a successful login, credentials are saved to ~/.weixin_cow_credentials.json. Subsequent startups reuse the saved credentials with no need to re-scan.

To force a re-login, delete the credentials file and restart.

Session expiry

When the WeChat session expires (errcode -14), CowAgent automatically clears old credentials and initiates a new QR login — no manual intervention required.
