MCP 服务器

Cinevva Game Engine

Turn the AI you already use into a game studio. Describe a game and Claude or Cursor builds it as a real 3D browser game: playable immediately, hosted on its own link, shareable with anyone. No engine, no build step, no code knowledge, nothing to export. Your AI ships the whole thing: it pulls free 3D assets, rigs characters, and playtests its own build until the game works. Free to start.

README

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

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.

Add to Cursor

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:

claude mcp add --transport http cinevva https://api.cinevva.com/create/mcp

Cursor: use the Add to Cursor button above, or add to ~/.cursor/mcp.json:

{
  "mcpServers": {
    "cinevva": { "url": "https://api.cinevva.com/create/mcp" }
  }
}

Cline: see llms-install.md, or add to your MCP settings:

{
  "mcpServers": {
    "cinevva": { "type": "streamableHttp", "url": "https://api.cinevva.com/create/mcp" }
  }
}

Gemini CLI: add to ~/.gemini/settings.json:

{
  "mcpServers": {
    "cinevva": { "httpUrl": "https://api.cinevva.com/create/mcp" }
  }
}

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.
