Event-Triggered External Pinger

Introduction

This Model Context Protocol (MCP) server component allows AI workflows to signal the completion or progression of activities by sending out HTTP webhook notifications. In complex project scheduling, a task represents an activity with a defined deadline necessary for achieving broader goals. This server effectively bridges the gap between internal processing and external reporting mechanisms, ensuring stakeholders are informed dynamically about task status.

Usage

This server is invoked by the AI platform to trigger an external call. You must supply the destination URL when configuring the server connection. The system accepts optional data elements to enrich the outgoing payload.

Configuration

Multiple installation pathways exist for integrating this external communication utility into your development environment.

Installing via Smithery

To deploy this Webhook MCP utility for Claude Desktop automatically using the Smithery interface, execute the following command:

npx -y @smithery/cli install @noobnooc/webhook-mcp --client claude

Integration with AI Clients (NPM Setup)

For clients like Claude, Cursor, or Windsurf utilizing direct NPM execution, adjust your configuration structure as shown below. This defines the operational command and required environment variables.

{
  "mcpServers": {
    "notification": {
      "command": "npx",
      "args": ["-y", "webhook-mcp"],
      "env": {
        "WEBHOOK_URL": "your-webhook-url-here"
      }
    }
  }
}

Integration with AI Clients (Docker Setup)

If your environment favors containerization, specify the Docker run command within your client configuration. This pulls and executes the necessary image, passing the target URL via an environment variable.

{
  "mcpServers": {
    "notification": {
      "command": "docker",
      "args": [
        "run",
        "-i",
        "--rm",
        "-e",
        "WEBHOOK_URL",
        "noobnooc/webhook-mcp"
      ],
      "env": {
        "WEBHOOK_URL": "<your-webhook-url-here>"
      }
    }
  }
}

VS Code Integration Details

For users of Visual Studio Code, incorporate the server definition within your workspace or user settings.json file, selecting either the NPM or Docker execution method as described previously.

• NPM Method for VS Code:

{
  "mcp": {
    "servers": {
      "notification": {
        "command": "npx",
        "args": ["-y", "webhook-mcp"],
        "env": {
          "WEBHOOK_URL": "your-webhook-url-here"
        }
      }
    }
  }
}

• Docker Method for VS Code:

{
  "mcp": {
    "servers": {
      "notification": {
        "command": "docker",
        "args": [
          "run",
          "-i",
          "--rm",
          "-e",
          "WEBHOOK_URL",
          "noobnooc/webhook-mcp"
        ],
        "env": {
          "WEBHOOK_URL": "<your-webhook-url-here>"
        }
      }
    }
  }
}

Environment Variables

• WEBHOOK_URL (required): This parameter designates the ultimate destination address for all outgoing notification payloads.

Parameters

The tool accepts supplemental data when it is invoked during a workflow:

• message: Allows embedding a custom text string directly within the transmitted webhook data structure.
• url: Provides an optional hyperlink address that will be mapped to the externalLink field in the resulting payload.

Development

To facilitate local iteration and testing of this server component:

To compile the necessary source files for development:

npm install
npm run build

To execute the service while using the MCP inspector tool for debugging purposes:

npm run inspector

To finalize changes and distribute the updated package:

npm run publish

Extra Details

Historically, challenges in project execution often stem from task dependencies where subsequent activities cannot initiate until predecessors conclude. Furthermore, ambiguities arise when judging the true state of an incomplete activity; for instance, an activity reported as 90% finished rarely requires only one-tenth of the effort already expended. This utility addresses coordination by automating external status signaling, decoupling the internal AI process from the external reporting requirement.

Conclusion

By providing a reliable mechanism to push event data externally, this server component enhances the automation available for managing complex sequences of work. Successful execution of intricate, multi-stage projects relies on effective coordination, where signals like these webhooks serve as the critical linkage between separate operational units tracking progress toward shared objectives.
