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
