Summary
This bridges Claude or Cursor to the PlayCanvas Editor through a Chrome extension and local runtime. You get programmatic control over entity hierarchies, component manipulation, asset creation, script injection, and material tweaking. The server exposes 20+ tools covering everything from duplicating entities and reparenting nodes to searching the PlayCanvas store and capturing viewport screenshots. Setup requires loading an unpacked Chrome extension and pointing your MCP config at the TypeScript server. Worth noting that it needs a Pro Claude account for reliable context windows, and only one Editor instance can connect at a time. Best for automating repetitive scene construction or letting an LLM handle bulk modifications to your 3D projects.

An MCP Server for automating the PlayCanvas Editor using an LLM.
[!IMPORTANT]
At the moment, the MCP Server needs to be driven by Anthropic's Claude. Our experience shows that the free tier for Claude does not deliver a big enough chat context to operate the MCP Server reliably. Therefore, we strongly recommend subscribing to a Pro Claude account.

Installation
Run npm install to install all dependencies.
Install Chrome Extension
- Visit
chrome://extensions/and enable Developer mode - Click
Load unpackedand select theextensionfolder - Load the PlayCanvas Editor. The extension should be loaded.
Run MCP Server
The MCP Server can be driven by Cursor or Claude Desktop.
[!TIP]
We have found Claude Desktop to be generally more reliable.
Claude Desktop
- Install Claude Desktop.
- Go to
Claude>Settings. - Select
Developerand thenEdit Config. - This will open
claude_desktop_config.json, your MCP Config JSON file.
Cursor
- Install Cursor.
- Select
File>Preferences>Cursor Settings. - Click
+ Add new global MCP server. - This will open
mcp.json, your MCP Config JSON file.
[!TIP]
Also inCursor Settings, selectFeaturesand scroll to theChatsection. ActivateEnable auto-run modeto allow the LLM to run MCP tools without requiring constant authorization. You do this at your own risk (but we prefer it)!
[!IMPORTANT]
In Cursor, ensure you haveAgentselected.AskandEditmodes will not recognize the MCP Server.
MCP Config JSON File
This is how your config should look:
Windows
{
"mcpServers": {
"playcanvas": {
"command": "cmd",
"args": [
"/c",
"npx",
"tsx",
"C:\\path\\to\\editor-mcp-server\\src\\server.ts"
],
"env": {
"PORT": "52000"
}
}
}
}
macOS
{
"mcpServers": {
"playcanvas": {
"command": "npx",
"args": [
"tsx",
"/path/to/editor-mcp-server/src/server.ts"
],
"env": {
"PORT": "52000"
}
}
}
}
Connecting the Editor to the MCP Server
The PlayCanvas Editor does not connect to the MCP Server automatically. To connect:
- Activate a Chrome tab running the PlayCanvas Editor.
- Select the Extensions icon to the right of the address bar.
- Select PlayCanvas Editor MCP Extension to open the extension popup.
- Select
CONNECT(the port number should match what is set in your MCP Config JSON File).
[!NOTE] You can currently only connect one instance of the PlayCanvas Editor to the MCP Server at any one time.
You should now be able to issue commands in Claude Desktop or Cursor.
