+### Example: Cursor
+
+1. Download and install [Cursor](https://www.cursor.com).
+2. Install `mcp-proxy` following the instructions in the [README](https://github.com/sparfenyuk/mcp-proxy).
+   For example, `uv tool install git+https://github.com/sparfenyuk/mcp-proxy`.
+3. Open the main Cursor Settings and select **MCP**.
+4. Click **Add new global MCP server** and add the Home Assistant server configuration:
+   ```json
+    {
+      "mcpServers": {
+        "Home Assistant": {
+          "command": "mcp-proxy",
+          "args": [
+            "http://localhost:8123/mcp_server/sse"
+          ],
+          "env": {
+            "API_ACCESS_TOKEN": "<your_access_token_here>"
+          }
+        }
+      }
+    }
+    ```
+5. Save your `mcp.json` file. You can also find this file in the `$HOME/.cursor/mcp.json` directory.
+6. Restart Cursor and return to the MCP settings. You should see the Home Assistant server in the list. The indicator should be green.
+7. In chat agent mode (Ctrl+I), ask it to control your home and the tool should be used.
