Cinevva Game Creator MCP Server

Name: Cinevva Game Creator
Author: cinevva

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

https://api.cinevva.com/create/mcp

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.

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.
