How to Set Up and Use MCP WeCom Bot
MCP WeCom Bot Server is a Go-based MCP server that enables AI assistants to send messages directly to WeCom (WeChat Work) group robots via the WeCom Webhook API. It supports multiple message types — plain text, Markdown, images, news cards, template cards, and file uploads — making it useful for AI-driven notifications, status updates, alert dispatching, and automated team communication within WeCom workspaces. Developers and DevOps teams use it to have Claude or other AI assistants post summaries, alerts, and reports to WeCom groups as part of automated workflows.
Prerequisites
- A WeCom (WeChat Work) account with a group robot configured (see https://developer.work.weixin.qq.com/document/path/91770)
- The WeCom group robot Webhook key (the UUID in the webhook URL after '?key=')
- A pre-compiled mcp-wecombot-server binary (download from releases or build from source with Go and make)
- An MCP client such as Claude Desktop
Create a WeCom group robot and get the Webhook key
In WeCom, open a group chat, click the group settings (three dots), select Group Robots > Add Robot, copy the Webhook URL. The key is the UUID in the URL: https://qyapi.weixin.qq.com/cgi-bin/webhook/send?key=YOUR_KEY_HERE
Install the server binary
Either download a pre-compiled release binary from the GitHub releases page, or build from source. Symlink or copy the binary into your PATH.
# Build from source
git clone https://github.com/gotoolkits/mcp-wecombot-server.git
cd mcp-wecombot-server && make build
sudo ln -s $PWD/dist/mcp-wecombot-server_linux_amd64 /usr/local/bin/mcp-wecombot-server
# Or install via Smithery
npx -y @smithery/cli install @gotoolkits/mcp-wecombot-server --client claude-desktopConfigure your MCP client
Add the server to claude_desktop_config.json with the WECOM_BOT_WEBHOOK_KEY environment variable set to your robot's Webhook key.

}Prompts to try
Example prompts that send messages to your WeCom group via the robot.
- "Send a text message to WeCom: 'Deployment to production completed successfully.'"
- "Send a Markdown message to WeCom with a heading '# Daily Report' and today's build status."
- "Send a news card to WeCom with title 'Incident Alert', description 'Database latency spike detected', and link to the dashboard."
- "Upload the error log file at /tmp/app.log to WeCom."
- "Send a template card to WeCom summarizing the test results."Troubleshooting MCP WeCom Bot
Messages fail with HTTP 400 or 'invalid webhook key'
The WECOM_BOT_WEBHOOK_KEY value must be only the UUID portion of the URL, not the full URL. Extract just the key after '?key=' from the WeCom robot webhook URL and set that as the env value.
'mcp-wecombot-server: command not found' when starting Claude Desktop
The binary is not on the system PATH that Claude Desktop sees. Either use the full absolute path as the 'command' value (e.g., '/usr/local/bin/mcp-wecombot-server'), or ensure the binary's directory is in the PATH loaded by your shell profile.
Image or file messages fail to send
Images sent via send_image must be Base64-encoded and under WeCom's size limit (2MB). For file uploads, use the upload_file tool which handles the multipart upload. Ensure the file path is accessible to the process running the MCP server.
