Webhook MCP Server

A Model Context Protocol (MCP) server that sends webhook notifications when called.

You can use this server with webhook notification services like Echobell to get notified when long-running tasks are completed. Simply configure the server with your Echobell webhook URL (or another service’s URL) and instruct your AI assistant to “send me a notification when it’s done” within your task prompts.

There are several ways to configure the MCP server:
