Overview

Expo MCP Server is the official remote-hosted Model Context Protocol server from Expo. It allows AI coding assistants (Claude, Cursor, VS Code, etc.) to deeply understand and interact with Expo and React Native projects.

Launched in late 2025 and continuously updated, it provides rich context including your exact SDK version, project configuration, running development server, simulators, and EAS services — dramatically improving AI assistance accuracy.

Key Features

Always Up-to-Date SDK Knowledge: Real-time access to the latest Expo SDK documentation and best practices
Project Context Awareness: Reads app.json, dependencies, configuration, and project structure
Development Environment Integration: Connects to running dev servers, iOS/Android simulators, and React Native DevTools
Workflow Automation: Install packages, configure settings, trigger EAS Builds, and manage deployment pipelines
EAS Integration: Direct tools for builds, submissions, and workflows (added 2026)
Visual Verification: AI can inspect running apps on devices/simulators for layout and behavior issues
Remote & Secure: Hosted at https://mcp.expo.dev/mcp with OAuth authentication

Requirements

An active EAS paid plan (Starter, Production, or Enterprise)
Expo account with linked projects

How It Works

Add the Expo MCP Server to your AI assistant
Authenticate via OAuth through the Expo dashboard
Start prompting with full project awareness, e.g.:
- "Update my notifications to use the latest Expo SDK pattern"
- "Debug why this component crashes on iOS simulator"
- "Create and trigger a production EAS build"

Supported Tools

Claude Code / Claude Desktop
Cursor
VS Code (MCP support)
Windsurf and other MCP-compatible clients
