Documentation Overview
Cinevva Game Creator MCP Server
Build and edit real 3D browser games from Claude, Cursor, Claude Code, or any MCP client. This is the public home of Cinevva's hosted MCP server: connect once and the AI you already use can read your game's code, edit it, import assets from a CC0 library, rig 3D models, playtest with screenshots and simulated input, and show the game as a playable widget right in the chat.
Server URL
Remote server, Streamable HTTP transport, OAuth 2.0 with dynamic client registration. You log in with your Cinevva account when your client connects. A free account works.
Setup
Claude (claude.ai and desktop): Settings → Connectors → Add custom connector. Name it Cinevva, paste the server URL, click Connect, and log in with your Cinevva account.
Claude Code:
Cursor: use the Add to Cursor button above, or add to ~/.cursor/mcp.json:
Cline: see llms-install.md, or add to your MCP settings:
Gemini CLI: add to ~/.gemini/settings.json:

How it works
File tools act on the authoritative server copy of your game, so your AI can read and edit code with or without a browser tab open. If you have the game open at cinevva.com/create, your tab picks up changes automatically. Runtime tools (console logs, screenshots, input simulation, asset import, rigging) drive a live browser session: open your game and click External agent in the creator toolbar to share it.
Tools
| Group | Tools |
|---|---|
| Read | list_game_files, read_files, search_game_file, read_console_logs, take_screenshot |
| Edit | edit_files, write_files, delete_files, rename_files |
| Preview | game_ready, show_game (renders the game as a playable in-chat widget on supported hosts) |
| Assets | search_assets, list_asset_packs, import_asset, search_fonts |
| 3D rigging | rig_model, apply_animation, list_animations, get_task_status |
| Testing | execute_js, simulate_input, list_live_sessions |
| Docs | list_library_docs, search_library_docs, read_library_docs |
Games are plain web games (Three.js or 2D canvas) served from <gameId>.cinevva.games. Editing and asset import are free, 3D rigging spends credits from your Cinevva balance.
