MCP System Bridge

A bridge implementation of the Model Context Protocol (MCP) that exposes native operating system features such as clipboard management, URL handling and date information retrieval.

Overview

mcp-sys-bridge provides a minimal set of tools for MCP compatible clients, allowing them to interact with the underlying OS in a safe manner.

Key Features

🚀 URL Opening — open one or multiple URLs in the default browser.
📋 Clipboard Support — copy text directly to the clipboard.
📆 Date Info — retrieve detailed information about the current date and time.

Installation

mcp-sys-bridge runs directly with uvx; no package installation is required. Add the server to your MCP configuration:

{
  "mcpServers": {
    "mcp-sys-bridge": {
      "command": "uvx",
      "args": ["mcp-sys-bridge"]
    }
  }
}

Ensure uv is installed following the uv documentation.

Quick Start

Start the bridge manually:

uvx mcp-sys-bridge
