Cinevva Game Creator — Claude Code MCP server: build games in chat
Hooks your AI client into a live Cinevva session: edit game files, pull CC0 assets, rig 3D models, playtest with screenshots.
claude mcp add --transport http game-creator https://api.cinevva.com/create/mcpWhat Cinevva Game Creator 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.
What it helps with
- edit game code without opening a browser
- find and import a CC0 asset
- grab a screenshot and read console logs after a run
- replay input and check how the game reacts
- rig a 3D model and attach an animation
Example prompts for the agent
- Read the game files and show me where platform collision is handled
- Find a CC0 model in the library and import it into the scene
- Open the game, hit External agent, and take a screenshot after the jump
