Claude Desktop extension (.mcpb)

:::warning Beta The .mcpb extension format is currently in beta. It works well for most users, but report any issues to GitHub Issues. For the most stable experience, use Homebrew or npm/npx. :::

:::tip Recommended for Claude Desktop The simplest, no-terminal way to add devcoach to Claude Desktop — one click, runs on Desktop's built-in runtime. :::

A single bundle that runs on Claude Desktop's built-in runtime — no Node or terminal required:

npm run mcpb        # → dist-mcpb/devcoach-<version>.mcpb
# Claude Desktop → Settings → Extensions → Install Extension… → pick the .mcpb

npm run mcpb:sign self-signs it (installs as an unverified publisher; a real code-signing certificate is needed for a verified signature). Prebuilt .mcpb releases and a Desktop directory listing are planned.
