Claude Code built my RPG world engine. Now it can also run the game, as the game master, over MCP.

A user developed Chronicle, an RPG world engine, with Claude Code, which now also functions as the game master over MCP. The system addresses the issue of context explosion by having each turn spawn a throwaway subagent (Sonnet 5.5) that loops work until the turn is complete. The main conversation then simply calls take_turn and last_scene. This project is available to build and try out.
