Overview

AI-generated overview

Hosted Cinevva server that lets an assistant read, edit and preview a live 3D browser game, import CC0 assets, rig models and playtest it.

What you can do
  • Read game files, search code, read console logs and take screenshots
  • Edit, write, delete and rename files in the server-side copy of the game
  • Preview the game and render it as a playable in-chat widget
  • Search and import CC0 assets and fonts from the asset library
  • Rig 3D models, apply and list animations, check task status
  • Run JavaScript, simulate input and list live sessions for playtesting
When to use it
For building or iterating on a Cinevva 3D or 2D canvas browser game from an MCP client, where the assistant should edit real game files, pull in assets and test the running game rather than produce code snippets.
Requirements
Remote Streamable HTTP endpoint at api.cinevva.com with OAuth 2.0 and dynamic client registration; a Cinevva account (a free account works) to log in when the client connects. Runtime tools such as screenshots, input simulation, asset import and rigging need the game open in a browser tab with the External agent option enabled.
Before you install
File tools change the authoritative server copy of the game, including delete and rename, and an open creator tab picks up changes automatically. 3D rigging spends credits from your Cinevva balance, while editing and asset import are free. Runtime tools drive a live browser session you explicitly share, and game content is served from Cinevva-hosted domains.

Installation

In SourceWeft

  1. Open Cinevva Game Creator in the dashboard and add it to a workspace.
  2. Connect the required credentials. They are stored privately and never shown on public pages.
  3. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/com.cinevva%2Fgame-creator/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.

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.

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.
