 MCPB files are signed MCP bundles that can be installed directly into Claude Desktop with a single click. Each platform (win-x64, linux-x64, osx-x64, osx-arm64) produces a separate `.mcpb` file containing trimmed server binaries. The bundles are signed using ESRP's Pkcs7DetachedSign operation and verified with the `mcpb verify` CLI.
