WeCom MCP server for AI agents

The MCP-WeCom Bot Server enables sending various types of messages to WeCom groups through a robot webhook. This tool simplifies the integration between your applications and WeCom (WeChat Work) by providing a standardized interface for sending text, markdown, image, news, and template card messages.

Installation Options

Installing via Smithery

For Claude Desktop users, the easiest way to install is through Smithery:

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

Manual Installation

To install manually:

# Clone the repository
git clone https://github.com/gotoolkits/mcp-wecombot-server.git

# Navigate to the directory and build
cd mcp-wecombot-server && make build

# Create a symlink to make the command available system-wide
sudo ln -s $PWD/dist/mcp-wecombot-server_xxx_xxxx /usr/local/bin/mcp-wecombot-server

Note: Replace $PWD/dist/mcp-wecombot-server_xxx_xxxx with the actual binary filename generated during the build process.

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

Configuration

Create a configuration file for the MCP server with your WeCom robot webhook key:

{
  "mcpServers": {
    "mcp-wecombot-server": {
      "command": "mcp-wecombot-server",
      "env": {
        "WECOM_BOT_WEBHOOK_KEY": "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxx"
      }
    }
  }
}

Important: You need to replace the WECOM_BOT_WEBHOOK_KEY value with your own webhook key from WeCom.

WeCom Robot Setup

To use this server, you'll need to set up a WeCom group robot first:

Follow the official WeCom documentation at: https://developer.work.weixin.qq.com/document/path/91770
After creating the robot, you'll get a webhook URL like: https://qyapi.weixin.qq.com/cgi-bin/webhook/send?key=693axxx6-7aoc-4bc4-97a0-0ec2sifa5aaa
Extract the key (the part after key=) and use it as your WECOM_BOT_WEBHOOK_KEY in the configuration.

How to install this MCP server

For Claude Code

To add this MCP server to Claude Code, run this command in your terminal:

claude mcp add-json "mcp-wecombot-server" '{"command":"mcp-wecombot-server","env":{"WECOM_BOT_WEBHOOK_KEY":"xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxx"}}'

See the official Claude Code MCP documentation for more details.

For Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > Tools & Integrations and click "New MCP Server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "mcp-wecombot-server": {
            "command": "mcp-wecombot-server",
            "env": {
                "WECOM_BOT_WEBHOOK_KEY": "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxx"
            }
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.
