SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This skill facilitates packaging a local MCP server into an MCPB bundle, enabling a self-contained runtime that runs without requiring the user to install Node, Python, or toolchains.

Core Features & Use Cases

  • Bundled runtime packaging: Create a distributable MCPB that includes the server and its runtime.
  • Cross-platform deployment: Produce bundles compatible with major desktop platforms for offline use.
  • Manifest-driven packaging: Use a structured manifest to define server entry points and configuration for distribution.

Quick Start

Run the MCPB packaging workflow to generate a self-contained local MCP server bundle ready for distribution.

Frequently Asked Questions about build-mcpb

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I package a local MCP server for offline desktop deployment?▼

You package a local MCP server for offline desktop deployment by compiling it into a self-contained MCPB bundle. This manifest-driven process embeds the server and its required runtime, ensuring execution without host toolchain dependencies.

Do I need Python or Node installed to run a bundled MCPB file?▼

No, you do not need Python or Node installed to run a bundled MCPB file. The packaging process bundles the necessary Node or Python runtimes directly within the distribution, enabling execution on systems lacking a host toolchain.

What is the best way to distribute local MCP servers without requiring a toolchain?▼

The best way to distribute local MCP servers without a toolchain is creating an MCPB bundle. This format enforces a manifest-driven build process to embed server entry points and runtimes, achieving self-contained cross-platform desktop compatibility.

How does manifest-driven packaging work for MCPB bundles?▼

Manifest-driven packaging for MCPB bundles works by using a structured manifest to define server entry points and configuration. This manifest directs the build process to assemble the server and its bundled runtime into a distributable archive.

Can I bundle both Node and Python runtimes into a single MCPB distribution?▼

Yes, you can bundle Node and Python runtimes into an MCPB distribution. The packaging process supports embedding both runtime environments to ensure self-contained execution for local MCP servers across different offline desktop platforms.

What security considerations apply when bundling runtimes into MCPB files?▼

Security considerations for bundling runtimes into MCPB files emphasize validating the embedded Node and Python environments to prevent unauthorized execution. The manifest-driven build process enforces compatibility and security checks for safe offline desktop distribution.
