Set up Expo MCP in VS Code

Build and manage React Native apps with Expo SDK guidance, EAS Build, EAS Update, simulator automation, and mobile development tools.

1

Locate the config file

VS Code reads MCP server configuration from the following file:

.vscode/settings.json → mcp section

Create this file if it does not already exist. For VS Code, this is inside your workspace .vscode/settings.json file under the mcp section.

2

Add the configuration

Add the following to your VS Code config file:

json
{
  "servers": {
    "expo-mcp": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "expo-mcp"
      ],
      "env": {
        "EXPO_TOKEN": "YOUR_EXPO_TOKEN"
      }
    }
  }
}
