What it does

MCP Bridge installs into the `packages` folder of a Cocos Creator 2.4.x project and starts a local HTTP server inside the editor (port 8200 by default, the next free port if it is taken). It binds to `127.0.0.1`. An MCP client connects to it through a small stdio proxy, `dist/mcp-proxy.js`. The agent gets more than thirty tools for working with the editor. The tools cover scene nodes (read, create, modify), components (add, remove, read), scripts (create, read, write, syntax check), assets (create, move, delete, info), materials, textures and particles. An offline mode for editing prefabs (`.prefab`) and scenes (`.fire`) is described separately: it creates assets from scratch, deep-clones with reference recalculation and reorders rendering. There are batch execution, global search, reference lookup for a node or asset, console reading, undo and redo, running menu items and building the project through `Editor.Builder`. Stability comes from a command queue (up to 100 items, a 429 answer beyond that), IPC timeouts and a guard on component properties against edits that crash the editor. Parameters such as `operation` instead of `action` are accepted as aliases to smooth over model mistakes. Until a project is picked with `set_active_instance`, only two basic tools are available. The settings panel can write the configuration for Claude Desktop, Cline, Roo Code and Trae.

Who it is for. Game developers on Cocos Creator 2.4 who want an agent to handle editor routine: placing nodes, editing prefabs and building.

Limitations

• Only Cocos Creator 2.4.x is supported: the plugin uses specific editor APIs and may not work on newer or older versions.
• A build is required: after copying into `packages` run `npm install` and `npm run build` (esbuild targeting es2018 for Electron 9.x), then start the server from the editor menu.
• The license is not clearly defined (GitHub shows NOASSERTION), so ask the author about terms of use.
• Documentation is in Chinese. The last commit dates from July 2026.

How to disable. Stop the server in the extension panel and delete the mcp-bridge folder from the project's packages. Remove the mcp-bridge entry from the client's mcpServers too.

README in short

The page lists the plugin's features (server, node, asset, component and script operations, offline prefab editing, command queue, property guard) and six Claude Code skills for developing the plugin itself. Then come the editor version, installation by copying into `packages`, the build, the start on port 8200, connecting clients automatically or by hand and the project directory layout.
