MCP Bundles (MCPB, formerly DXT) is a packaging format and CLI tool for distributing local MCP servers as zip archives with a manifest, enabling one-click installation in desktop apps like Claude. The repo includes the bundle specification, a CLI for creating and packing bundles, and loader/verification code used by Claude for macOS and Windows.
Use cases
- package a local MCP server into a distributable bundle
- one-click install of MCP servers in desktop AI apps
- create a manifest. for an MCP server
- add MCPB bundle support to a desktop application
- distribute MCP servers with automatic updates
- rename DXT tooling to MCPB in existing projects
When to choose
- you develop local MCP servers and want easy distribution and installation
- you build desktop apps that should support one-click MCP server installation
- you want a Chrome-extension-like packaging format for MCP tooling
When to avoid
- you need remote/hosted MCP server deployment rather than local bundles
- you only need to run MCP servers without packaging or distribution
- you target platforms whose apps don't implement MCPB support
