SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill packages a local MCP server with its runtime, enabling it to run without needing Node, Python, or any toolchain on the user's machine. It addresses the need for a standalone MCP server that can interact with local files, desktop apps, or OS functionalities.

Core Features & Use Cases

  • Local MCP Server Packaging: Packages the MCP server and its runtime into a single file (MCPB).
  • User-friendly Execution: Installs and runs with one file, without dependencies on the user's system.
  • Use Case: Ideal for developers and users who require an MCP server for local tasks that cannot be handled by remote servers.

Quick Start

Use the 'build-mcpb' skill to package your MCP server 'my-server.mcp' and generate an MCPB file named 'my-server.mcpb'.

FAQPage Schema
How do I package a local MCP server into a standalone file?▼

To package a local MCP server, you bundle the server and its runtime into a single MCPB file. This ensures the server runs independently without requiring Node.js, Python, or any toolchain on the target machine.

Can I package MCP servers written in Python and Node.js?▼

Yes, you can package MCP servers written in Python and Node.js. The packaging process also supports binary MCP servers, capturing all necessary dependencies within the standalone MCPB file for execution.

When do I need to bundle an MCP server with its runtime?▼

You need to bundle an MCP server with its runtime when distributing it to machines that lack the required toolchain. This allows the server to interact with local files, desktop apps, or OS functionalities without local dependencies.

Does a packaged MCPB file require dependencies on the user's system?▼

No, a packaged MCPB file does not require dependencies on the user's system. The packaging process includes all necessary runtime components inside the file, allowing installation and execution with one file.

What is the best way to distribute an MCP server for local desktop tasks?▼

The best way to distribute an MCP server for local desktop tasks is generating an MCPB file. This standalone format ensures user-friendly execution by decoupling the server from the user's local toolchain.

Why does my MCP server fail to run on another machine without Python installed?▼

An MCP server fails without Python because the target machine lacks the required runtime toolchain. Packaging the server and its runtime into a standalone MCPB file resolves this by including all dependencies internally.
