How to use Webhook MCP Server?
Configure the server in your MCP client (Claude, Cursor, Windsurf, or VS Code) by setting the WEBHOOK_URL environment variable to your webhook endpoint. The server is run either via npx -y webhook-mcp or using the Docker image noobnooc/webhook-mcp. Instruct your AI assistant to “send me a notification when it’s done” to trigger the webhook.

Frequently asked questions
How do I configure Webhook MCP Server for Claude?
Add the server configuration to your Claude desktop config with a JSON block that sets the command (`npx` or `docker`) and passes `WEBHOOK_URL` as an environment variable. See the README for exact examples.
What optional parameters can I pass to the webhook?
You can include a `message` (custom text) and a `url` (an external link) in the webhook payload.
Can I use a webhook service other than Echobell?
Yes. The server sends a POST request to any HTTP webhook URL you provide. Echobell is only one example.
Does Webhook MCP Server support Docker?
Yes. A Docker image (`noobnooc/webhook-mcp`) is available and can be configured using the same environment variable.
