WebMCP
Connect a browser AI agent so it can drive the editor and build your game.
Connect a browser AI agent so it can build your game by driving the editor directly. When it's on, a supported browser agent can use the editor's tools — no terminal needed, unlike the Local MCP Server.
Experimental
WebMCP is experimental and not available in most browsers yet — it relies on the WebMCP browser API, which may not work for you and can change without notice. If you just want an agent to drive the editor today, use the Local MCP Server instead.
Turn it on
- Open Settings → Configure AI and enable WebMCP. If the toggle is disabled, your browser doesn't support WebMCP yet.
- Keep the editor tab open and focused so your browser agent can use the editor's tools.
Check it works
With WebMCP enabled, ask your browser agent to do something and watch the editor:
Use the vibe games editor tools. Add a spinning cube to the scene.
The agent's tool calls appear in the editor's chat as it works. The WebMCP badge at the bottom of the chat panel shows whether the agent is ready, working, or unsupported.
WebMCP tools live only in this tab. Keep the editor tab open while the agent is connected.
