Cocos Creator MCP Server
Cocos Creator MCP Server Plugin
An MCP server as a Cocos Creator editor extension: the agent controls scenes, nodes, components, prefabs and project assets
Medium risk
We rate an entry medium when the tool runs code, makes network calls or reads project files. Check what exactly it does before installing.
Why this level
- Runs a local server inside the editor and controls the project
- Creates and changes scenes, nodes, prefabs and assets, and can build the project
Install
Manual install
cd extensions/cocos-mcp-server
npm install
npm run buildFirst copy the cocos-mcp-server folder into the project's extensions directory, then build it. After the build, enable the extension and start the server from its panel.
This is third-party code. Review the repository files before installing.
What it does
The plugin installs into the Cocos Creator 3.8.6 or newer editor and runs an MCP server inside it over the Streamable HTTP protocol. The open-source edition offers about 50 tools that cover scenes, nodes, components, prefabs, assets, project settings, builds, debugging and preferences. Tools follow an opcode plus parameters scheme, which simplifies calls from the agent. Nodes can be addressed by UUID, by a path like Canvas/Panel/Button or by name. The server starts from the extension panel, the default port is 3000, and the agent connects at http://127.0.0.1:3000/mcp.
Who it is for. For Cocos Creator game developers who want to build and edit scenes and objects through an agent.
Good fit when
- You need to build or change a scene and nodes from a description
- You need to create a prefab from nodes and reuse it
- You need to manage components and assets from a chat with the agent
Not a fit when
- The project uses a Cocos Creator version older than 3.8.6
- You cannot install editor extensions or run a local server
Example request
Create a Button node inside Canvas/Panel and add a cc.Button component to itLimitations
It needs Cocos Creator 3.8.6 or newer, and the plugin installs by copying into the project's extensions folder and then building it. This is the open-source edition; the author and the company VberAI offer a separate paid Pro edition, and some capabilities in the README, such as the set of 16 intent-level tools, the built-in knowledge base and animation and Spine work, belong to Pro. The server runs locally without keys, and access is limited to your machine.
How to disable. Stop the server in the extension panel and remove the cocos-mcp-server folder from the project's extensions directory, then refresh the extension list.

README in short
The README describes an extension plugin for Cocos Creator 3.8.6 or newer that gives AI assistants editor control through MCP over Streamable HTTP. The open-source edition is condensed to about 50 tools on an opcode plus parameters scheme, covering scenes, nodes, components, prefabs, assets, builds, debugging and preferences. Installation is described step by step: copy the folder into the project's extensions, run npm install and npm run build, enable the extension and start the server from the panel, with a default port of 3000. It provides config snippets for the Claude CLI, the Claude client and Cursor-family editors. A large part of the README covers the paid Pro edition by the company VberAI. The README is available in several languages, including Russian.
FAQ
How does the open edition differ from Pro?
The open edition offers about 50 editor control tools. Pro by VberAI is paid and adds intent-level tools, a built-in knowledge base and animation and Spine work.
How does the agent connect to the server?
After you start the server from the panel it listens on http://127.0.0.1:3000/mcp or your port, and this address goes into the MCP client config as an http transport.
