About WeCom Group Robot (mcp-wecombot-server)

mcp-wecombot-server is an MCP server application that sends various types of messages to a WeCom (WeChat Work) group robot. Through a group robot webhook key, it exposes tools to send text, markdown, image, news (graphic), and template-card messages, as well as to upload files to WeCom. It is built in Go and installed either via Smithery for Claude Desktop or by building/downloading the binary and registering it in your MCP client's configuration with the WECOM_BOT_WEBHOOK_KEY environment variable.

When to use it

  • Let an AI assistant push notifications, alerts, or status updates to a WeCom group chat

  • Share images, graphic (news) cards, or template cards in a WeCom group from an automated workflow

Security notes

Authentication is via the WeCom group robot webhook key, passed as the WECOM_BOT_WEBHOOK_KEY environment variable. Anyone holding this key can post messages to the target WeCom group, so treat it as a secret and avoid committing it to source control. The key corresponds to the `key` parameter of the WeCom webhook URL (https://qyapi.weixin.qq.com/cgi-bin/webhook/send?key=...).

WeCom Group Robot (mcp-wecombot-server) FAQ

What is WECOM_BOT_WEBHOOK_KEY and where do I get it?

It is the WeCom group robot's webhook key. In the robot's webhook URL (https://qyapi.weixin.qq.com/cgi-bin/webhook/send?key=693axxx6-7aoc-4bc4-97a0-0ec2sifa5aaa), the value after `key=` is your WECOM_BOT_WEBHOOK_KEY. See the WeCom robot configuration guide at https://developer.work.weixin.qq.com/document/path/91770.

How do I install it?

You can install automatically for Claude Desktop via Smithery (`npx -y @smithery/cli install @gotoolkits/mcp-wecombot-server --client claude-desktop`), or manually by cloning the repo and running `make build`, then symlinking the produced binary into your PATH (or downloading a precompiled release binary).

What kinds of messages can it send?

Text, markdown, images, news (graphic) messages with title/description/url/picurl, and template cards. It can also upload files to WeCom.

Is this an official WeCom/Tencent product?

No. It is a third-party open-source project by gotoolkits that uses the public WeCom group robot webhook API; it is not published by Tencent/WeCom.
