What the package includes

Use the typed service contracts from your application, launch a local MCP bridge for an agent, or adapt the examples. The included skill helps an agent decide which small questions are worth offloading.

The engine is separate

The System One Engine application and studio are private-source software. The open-source launcher downloads a version-pinned, checksum-verified compiled runtime under its separate preview license. It starts the local engine and opens Studio. The npm package contains the launcher and integrations; application source remains private.

The app is available as a local preview. The public package can be inspected and built independently. Provider credentials stay with the engine.
