SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires @anthropic-ai/mcpb, and includes scripts (resource) components.

What problem does it solve?

This Skill addresses the challenge of packaging and distributing local MCP servers, allowing users to run servers with their runtime bundled in a single file.

Core Features & Use Cases

  • Single-File Distribution: Package the server and its dependencies into a single .mcpb file for easy installation.
  • No External Dependencies: No need for Node, Python, or other toolchains, enabling users to run the server on any machine.
  • Use Case: For developers who need a server that interacts with the local filesystem, desktop apps, or OS and can be installed without the user having Node/Python set up.

Quick Start

Use the build-mcpb skill to package the server located in the 'server' directory into a .mcpb file named 'my-server.mcpb'.

FAQPage Schema
How do I package a local MCP server into a single file for distribution?

You can package a local MCP server by bundling the server and its dependencies into a single .mcpb file. This produces a self-contained, runnable server package for local distribution without requiring additional runtime environments on the target machine.

Can I run a distributed MCP server on a machine without Node.js or Python installed?

Yes, a packaged .mcpb file runs without Node.js, Python, or other toolchains on the target machine. The runtime is bundled within the single file, enabling users to install and run the server without setting up a local development environment.

Do I need Node.js installed to build and package a local server into a .mcpb file?

Yes, Node.js must be installed on the host machine to package the local MCP server. Node.js is required for the build process to bundle the server and its dependencies into the final .mcpb file for distribution.

What is the best way to distribute a local MCP server that interacts with the filesystem?

The best way to distribute a local filesystem-interacting MCP server is packaging it into a .mcpb file. This single-file approach bundles all dependencies, allowing installation on machines where users lack Node or Python setups.

What are the limitations of using .mcpb files for local server distribution?

A limitation of .mcpb packaging is that Node.js is required on the host machine to perform the build process. Additionally, this approach is specifically designed for local server distribution scenarios rather than remote or cloud-based deployments.
