# MCP live (AI builds the graph)

**Category:** Showcases  
**Live demo:** https://xenolithengine.github.io/xenolith-graph/examples/mcp-live/  
**Frameworks shipped:** react

## Description

Start @xenolithengine/graph-mcp-server locally, click Connect, then ask Claude Desktop / Cursor to build a graph. The AI calls list_node_types → add_node → connect_pins → auto_layout. "I describe it, the editor builds it."

## Source files

  - [react] demos/MCPDemo.tsx

## How to use this example

Open the live demo at https://xenolithengine.github.io/xenolith-graph/examples/mcp-live/ to interact with it in the browser. The same source files are
reproduced verbatim in the page so you can copy-paste into your own project. Every example is
self-contained — pick one, copy the files, install `@xenolithengine/graph-editor` + the relevant framework
adapter, and it runs.
