Cocos

You install and run a dedicated MCP server for Cocos Creator 3.8+ that lets an AI assistant interact with the editor through a standardized protocol. With a single setup, you unlock automated scene, node, prefab, asset, and project operations, plus debugging, preferences, server messaging, and more, all accessible from your preferred MCP client.

How to use

To use the MCP server with an MCP client, start the server panel from your editor’s Extensions menu and ensure the HTTP endpoint is reachable at the configured port. Your MCP client connects to the endpoint to issue actions such as opening scenes, querying nodes, creating prefabs, managing assets, running the project, and broadcasting messages. The server exposes a comprehensive set of capabilities that map to editor operations, enabling you to automate repetitive tasks, integrate AI-driven workflows, and coordinate complex editor interactions through standard requests.

How to install

Prerequisites you need before installation:

1. Install Cocos Creator 3.8.6 or higher on your system.

2. Ensure Node.js is available in your environment (Cocos Creator provides Node.js as part of the editor bundle, but you may need it for building the plugin).

3. Prepare your project for extensions by creating an extensions folder if it does not exist.
