SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill helps you package a local MCP server so it can be installed and run on a user's machine without requiring them to install Node, Python, or any build toolchain first.

Core Features & Use Cases

  • Bundled Distribution: Prepare an MCPB bundle that includes the server, its runtime, and packaged dependencies in a single installable file.
  • Local Machine Integrations: Use it for servers that need filesystem access, desktop app control, localhost communication, or OS-level APIs.
  • Manifest and Launch Setup: Define the package manifest, entry point, compatibility requirements, user configuration, and stdio launch command for reliable installation.
  • Security Guidance: Follow the included local security references to validate paths, avoid command injection, limit resource usage, and protect secrets.
  • Use Case: Package a Node-based file browser MCP server so a user can drag in one bundle and immediately access approved local directories.

Quick Start

Ask me to turn your local MCP server into a distributable MCPB bundle with a valid manifest, bundled runtime, and safety checks.

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 into a single installable file?▼

To package a local MCP server, you bundle the server, its runtime, and dependencies into a single installable .mcpb file. This requires defining a valid manifest, stdio launch configuration, and platform compatibility metadata so it runs without requiring users to install Node or Python first.

What is an MCPB bundle used for?▼

An MCPB bundle is used to ship local MCP servers that need filesystem access, desktop app control, localhost communication, or OS-level API integration. It allows users to install and run these servers on their machines without needing a build toolchain.

Can I bundle a Python MCP server with its runtime for distribution?▼

Yes, you can bundle Node or Python MCP servers with their packaged dependencies and local runtime. The packaging process requires a valid manifest and platform compatibility metadata to ensure the server installs and runs correctly on the user's machine without manual environment setup.

What security controls are needed for local MCP servers accessing the filesystem?▼

Security controls for local MCP servers include validating paths, avoiding command injection, limiting resource usage, and protecting secrets. The packaging process requires explicit security references to handle untrusted local operations safely during filesystem access and desktop app control.

Do I need to configure a stdio launch command when packaging an MCP server?▼

Yes, configuring a stdio launch command is required when packaging an MCP server. The manifest setup requires an entry point, compatibility requirements, user configuration, and a stdio launch command to ensure reliable installation and execution on the user's local machine.
