Introduction to Model Context Protocol Bundle (MCPB)

What is MCPB?

The Model Context Protocol Bundle (MCPB) is a standardized packaging format designed to simplify the distribution and usage of Model Context Protocol (MCP) servers. For ToolUniverse, the MCPB wraps the entire ecosystem—including Python dependencies, the Node.js bridge, and the server logic—into a single, standalone executable or bundle.

Why use MCPB with ToolUniverse?

Traditionally, running an MCP server like ToolUniverse required setting up a specific Python environment, installing dependencies.

MCPB solves this by providing:

  • Zero Configuration: No need to manage Python virtual environments or install Node.js manually.

  • One-Click Installation: In supported clients like Claude Desktop, you just drop the .mcpb file.

  • Portability: The bundle contains everything needed to run ToolUniverse on your machine.

Key Features

  • Standalone Execution: The bundle acts as a self-contained server.

  • Seamless Integration: Designed specifically for Claude Desktop and other MCPB-aware clients.

  • Access to Scientific Tools: Immediately unlocks 700+ scientific tools for your AI assistant without command-line setup.

Getting Started

To use the ToolUniverse MCPB:

  1. Download the latest release from our GitHub Releases.

  2. Follow the instructions in the official Claude Desktop Guide to configure it with your client.
