SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

MCPB bundles a local MCP server with its runtime so end users can install and run the server without requiring Node or Python or a separate toolchain, enabling offline deployment and distribution.

Core Features & Use Cases

  • Create self-contained MCPB bundles containing manifest.json, server code, and bundled dependencies.
  • Cross-platform distribution enabling running MCP servers on Windows, macOS, and Linux.
  • Simple packaging and installation workflow via host UI or command line.

Quick Start

Pack your MCP server into a local-files.mcpb by running the MCPB pack workflow and install it using the host UI.

FAQPage Schema
How do I package a local MCP server with its runtime for distribution?▼

Package a local MCP server with its runtime by bundling the manifest.json, server code, and bundled dependencies into a portable MCPB archive. This workflow ensures the server is self-contained and installable across Windows, macOS, and Linux.

Do end users need Node or Python installed to run a distributed MCP server?▼

End users do not need Node or Python installed to run a distributed MCP server. MCPB bundles a local MCP server with its runtime, ensuring a zero-dependency end-user runtime for offline deployment and installation.

What is an MCPB archive and when do I need it for desktop server distribution?▼

An MCPB archive is a self-contained bundle containing a manifest, server code, and bundled dependencies. You need it when distributing desktop MCP servers or system-level integrations across Windows, macOS, and Linux without requiring a separate toolchain.

Can I distribute cross-platform MCP servers for Windows, macOS, and Linux using MCPB?▼

You can distribute cross-platform MCP servers for Windows, macOS, and Linux using MCPB. It enforces a standard packaging workflow via manifest schemas to ensure installable, self-contained servers across these operating systems.

How do I install and run a packaged MCPB bundle on a local machine?▼

Install and run a packaged MCPB bundle using the host UI or command line. After packing your MCP server into a local-files.mcpb archive via the MCPB pack workflow, the host handles the simple installation process.

What are the limitations of bundling MCP servers with a zero-dependency runtime?▼

The zero-dependency runtime ensures self-contained execution but requires adherence to standard manifest schemas for packaging. Developers must bundle all necessary server code and assets into the MCPB archive to ensure cross-platform compatibility without external toolchains.
