SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

MCPB bundles a local MCP server with its runtime into a single portable package, enabling offline deployment without requiring the user to install Node, Python, or toolchains.

Core Features & Use Cases

  • Bundles server code (server/), a manifest.json, and a runtime into a single .mcpb archive.
  • Defines an entry point and config for a stdio MCP server with a documented mcp_config.
  • Supports local desktop apps and OS integration by packaging dependencies and enabling offline distribution.

Quick Start

Run the MCPB packaging workflow on your MCP project to produce a distributable .mcpb bundle.

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

To package an MCP server for offline deployment, bundle the server code, a manifest.json, and the required runtime into a single portable .mcpb archive. This self-contained bundle allows the server to run locally without requiring users to install separate toolchains.

What is an MCPB bundle and when do I need it?▼

An MCPB bundle is a self-contained archive that packages a local MCP server with its runtime, enabling offline distribution. You need it when distributing a server to environments without Node, Python, or toolchain access, such as local desktop applications.

Do I need Python or Node installed to run a packaged MCP server?▼

No, you do not need Python or Node installed to run a packaged MCP server. The MCPB bundle includes the necessary runtime and dependencies within the archive, allowing the server to execute independently without a separate toolchain.

How do I configure environment variables and entry points in an MCPB manifest?▼

You configure environment variables and entry points by defining them within the mcp_config section of the manifest.json. This manifest-driven workflow supports environment substitution and validation steps to correctly set up the stdio MCP server.

What's the best way to distribute a local MCP server with filesystem access?▼

The best way to distribute a local MCP server with filesystem access is creating an MCPB bundle. It packages the server code and runtime together, satisfying manifest and packaging requirements for secure, offline local deployment.
