WeCom Bot is an MCP server that enables Claude to send different types of messages to WeCom (WeChat Work) group robots. It supports text, markdown, image, news, and template card messages, allowing for rich communication with teams through WeCom's enterprise messaging platform. This integration bridges AI assistants with enterprise communication channels, making it easy to send notifications, alerts, or information directly to WeCom groups without manual copying and pasting.

Overview

WeCom Bot allows Claude to send various types of messages to WeCom (WeChat Work) group robots. This integration is particularly useful for teams that use WeCom as their primary communication platform and want to automate message sending through AI assistants.

Prerequisites

Before using this MCP, you need:

A WeCom account with permission to create and configure group robots
The webhook key for your WeCom group robot

Installation

Option 1: Install via Smithery (Recommended)

If you're using Claude Desktop, you can install WeCom Bot automatically using Smithery:

npx -y @smithery/cli install @gotoolkits/mcp-wecombot-server --client claude-desktop

Option 2: Manual Installation

Clone the repository:

git clone https://github.com/gotoolkits/mcp-wecombot-server.git

Build the application:
```
cd mcp-wecombot-server
make build
```
Create a symbolic link to make it globally available (optional):
```
sudo ln -s $PWD/dist/mcp-wecombot-server_xxx_xxxx /usr/local/bin/mcp-wecombot-server
```
(Replace mcp-wecombot-server_xxx_xxxx with the actual binary filename)

Alternatively, you can download a pre-compiled binary from the releases page.

Configuration

To configure the MCP in your Claude client, add the following to your configuration:

{
  "mcpServers": {
    "mcp-wecombot-server": {
      "command": "mcp-wecombot-server",
      "env": {
        "WECOM_BOT_WEBHOOK_KEY": "your-webhook-key-here"
      }
    }
  }
}

Replace your-webhook-key-here with your actual WeCom robot webhook key. You can find this key in the URL provided when you create a robot in WeCom: https://qyapi.weixin.qq.com/cgi-bin/webhook/send?key=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxx

The part after key= is your webhook key.

WeCom Robot Setup

To set up a WeCom group robot:

Open WeCom and navigate to the group where you want to add the robot
Click on the group name to access group settings
Select "Group Robot" and click "Add Robot"
Choose "Custom Robot" and configure the robot settings
After creation, you'll receive a webhook URL - extract the key from this URL

For detailed instructions, refer to the official WeCom documentation.
