WeCom is the enterprise version (using in office) of the famous all-in-on IM WeChat envied by Elon Musk.

Setup

# Navigate to skill directory
cd skills/wecom
Install dependencies
npm install
Build TypeScript
npm run build
Set webhook URL
export WECOM_WEBHOOK_URL="https://qyapi.weixin.qq.com/cgi-bin/webhook/send?key=YOUR_KEY"

Usage with Claude Code

Add to your ~/.config/claude_code/mcp.json:

{
  "mcpServers": {
    "wecom": {
      "command": "node",
      "args": ["/path/to/clawdbot/skills/wecom/dist/index.js"],
      "env": {
        "WECOM_WEBHOOK_URL": "https://qyapi.weixin.qq.com/cgi-bin/webhook/send?key=YOUR_KEY"
      }
    }
  }
}

Then restart Claude Code. You'll have three new tools:
