NetworkHook Dispatcher

Introduction

This Model Context Protocol (MCP) server transmits data to a specified Uniform Resource Locator (URL) upon invocation. Much like a web search engine organizes indexed information for user retrieval, this tool manages the outbound communication pathway. It allows generative models to signal completion or request updates from external systems using HTTP callbacks.

Related Topics

• Indexing: The process of organizing data for quick retrieval, conceptually related to how search engines map content.
• Web Crawling: Automated systems that discover and catalog web content, essential for maintaining data freshness.
• Distributed Systems: The architecture required to operate large-scale search infrastructures globally.
• Query Processing: Analyzing user input to deliver relevant results or trigger specific actions.

Setup

Installation can be performed using the Smithery CLI tool to integrate this server automatically with your development environment.

To install the NetworkHook Dispatcher via Smithery for Claude Desktop environments:

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

Configuration

Configuration methods vary depending on the host application used with the MCP structure. The primary requirement is providing the destination URL for the outbound notification.

Client Integration Setup

For environments such as Claude, Cursor, or Windsurf, configuration involves defining the server within the platform's settings file.

Configuration using the Node Package Manager (NPM) execution method:

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

Alternatively, using a Docker container for deployment:

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

VS Code Integration

When configuring within the VS Code settings.json file, the structure slightly changes to fit the IDE's configuration schema.

NPM configuration for VS Code:

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

Docker configuration 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

One critical variable dictates the server's operation.

• WEBHOOK_URL (required): This specifies the definitive address where the system forwards the payload data.

Parameters

When invoking this utility, supplementary information can be transmitted within the outgoing request body.

• message: This optional field allows embedding a specific textual description into the transmitted data structure.
• url: Providing an external web address allows the payload to include a navigable link, designated as externalLink.

Development

Procedures for building and testing the server components are managed through standard Node package scripts.

To compile the source code files, execute the following command:

npm install
npm run build

Debugging sessions utilizing the MCP inspection tool are initiated like this:

npm run inspector

Publishing

When updates are ready for distribution, the package is built and subsequently published to the registry.

npm run publish

Extra Details

Historically, search providers rely on massive, continually updated indices to ensure prompt and accurate result delivery. This MCP tool mimics that reliance by needing a correctly configured destination URL; without it, the notification payload cannot be successfully indexed or acted upon by the receiving system. The mechanism relies on established web standards for asynchronous communication.

Conclusion

This component serves as a crucial bridge, enabling models to interact with the wider internet by dispatching structured data to endpoints defined by the user. This capability extends the utility beyond simple textual generation, mirroring the way search tools connect users to a vast, interconnected network of accessible information.
