## About MCP Bundles (MCPB)
MCP Bundles, formerly Desktop Extensions (DXT), are .mcpb zip archives containing a local MCP server and a manifest describing it, similar in spirit to browser or editor extensions. The repository contains the bundle specification, the mcpb CLI for building bundles, and the code Claude for macOS and Windows uses to load and verify them.

## Install

```
npm install -g @anthropic-ai/mcpb
```
