How do I use kenchiku-mcp?

1. Click on "Install Server". 2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state. 3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@kenchiku-mcp insert a window block at coordinates 50,100 with scaling 2.5x1.0" That's it! The server will respond to your query, and you can continue using it as needed. Here is a step-by-step guide with screenshots.
