Hooks your AI client into a live Cinevva session: edit game files, pull CC0 assets, rig 3D models, playtest with screenshots.

## What it does

The server is remote and speaks Streamable HTTP at `https://api.cinevva.com/create/mcp`. Sign-in uses OAuth 2.0 with dynamic client registration against your Cinevva account. A free account is enough.

File tools work on the server-side copy of the game, so a browser tab is optional: `list_game_files`, `read_files`, `search_game_file`, `edit_files`, `write_files`, `delete_files`, `rename_files`. Runtime work is a different story. Console logs, screenshots, input simulation, asset import and rigging all need a live session, so open the game and hit **External agent** in the creator toolbar. Editing and asset import cost nothing; rigging a 3D model draws credits from your Cinevva balance. Games are plain web builds on Three.js or 2D canvas, served from `<gameId>.cinevva.games`.

A few extras round it out. `show_game` renders the game as a playable widget inside the chat on hosts that support it, `execute_js` and `simulate_input` cover testing, and the docs group (`list_library_docs`, `search_library_docs`, `read_library_docs`) answers library questions. The server is listed in the official MCP registry as `com.cinevva/game-creator`.
