Упаковка MCP-сервера в бандл .mcpb

★ 8.6 · devops

build-mcpb is a Claude Code skill that guides developers through packaging a local MCP server together with its Node or Python runtime into a single installable .mcpb file. The bundle is a zip archive containing a `manifest.json`, server code, and vendored dependencies — end users install one file with no need for Node, Python, or any toolchain on their machine. The skill covers manifest structure (schema v0.4), launch configuration via `mcp_config`, install-time user settings in `user_config` with native UI controls like directory pickers, and the build pipeline using `npx @anthropic-ai/mcpb pack` for both Node and Python targets. It applies when the server must access the local filesystem, drive desktop apps, or call OS-level APIs — cases where a remote HTTP server is not an option. Security is explicitly the developer's responsibility: MCPB provides no sandbox, so path validation and privilege scoping must be handled in server code.
