Wecom

Send messages to WeCom (企业微信) via webhooks using MCP protocol. Works with Claude Code, Claude Desktop, and other MCP clients.

WeCom Skill

Send text and markdown messages to WeCom (企业微信) via incoming webhooks (ENV: WECOM_WEBHOOK_URL).

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

Setup

bash

# 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:

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:

Tools

send_wecom_message

Send a text message to WeCom.

bash

# Simple message
await send_wecom_message({ content: "Hello from OpenClaw!" });

# With mentions
await send_wecom_message({
  content: "Meeting starting now",
  mentioned_list: ["zhangsan", "lisi"]
});

send_wecom_markdown_v2

Send a markdown_v2 message to WeCom. Recommended — supports tables, code blocks, nested blockquotes, H1-H3 headers, and all standard markdown.

bash

await send_wecom_markdown_v2({
  content: `# Annual Report
