Release v4.47.0
The Screenplay MCP server can now draw the application as an event model board inside MCP hosts that render MCP Apps views, including what a proposal or a what-if sketch would change before anything is written.
Added
visualize-modeldraws the model on disk as an event model board in the host's view, for hosts that advertise the MCP Apps extension (io.modelcontextprotocol/ui). Other clients see the server unchanged. See See a model as an event model board with MCP.visualize-modelwith aproposalIdshows what an outstanding proposal would make of the application, beforeapply.visualize-modelwith asketchof whole.playdocuments draws a what-if over the model on disk without validating it as a proposal or writing it.- The board switches between the current and the proposed model, offers detail level, properties and connection style, draws again from the model, and goes fullscreen where the host allows it. The model is told what the change adds and removes; the documents go only to the board.
Changed
- The VS Code extension's board takes its Cratis logo and View menu from
@cratis/event-models0.109.0; the choices are still remembered across boards and sessions.
