+## AI Agent Integration (Model Context Protocol)
+
+Connect AI assistants (Claude Desktop, Google Gemini, Cursor IDE) directly to your factory floor or i3X gateway:
+
+```bash
+# Run the MCP server directly via npx
+I3X_SERVER_URL=http://127.0.0.1:8000 npx @node-i3x/mcp
+```
+
+Add to your `claude_desktop_config.json`:
+```json
+{
+  "mcpServers": {
+    "node-i3x": {
+      "command": "npx",
+      "args": ["-y", "@node-i3x/mcp"],
+      "env": {
+        "I3X_SERVER_URL": "http://127.0.0.1:8000"
+      }
+    }
+  }
+}
+```
+
+Now Claude or Cursor can diagnose machinery in single turns:
+- `"Inspect Boiler_101. Is current temperature normal according to its schema definition?"`
+- `"Explore plant hierarchy and summarize any assets with Bad quality flags."`
+- `"Query telemetry trends for Pump_101 over the last 2 hours."`
+
+See [`packages/mcp`](./packages/mcp) for full documentation.
