What is AppContext?
AppContext is a personal MCP hub for macOS. It aggregates every MCP server you use behind one endpoint and adds live visual context from your iOS simulator and Chrome browser — so your AI coding agent can actually see what you're building.
Configure your MCP servers once in AppContext. Use them in Claude Code, Cursor, Claude Desktop, Windsurf, or any MCP client. Switch between AI tools without reconfiguring anything.
Features
- MCP Hub: Aggregate any number of MCP servers (stdio or SSE) behind one endpoint. One-click import from Claude Code, Cursor, and Claude Desktop configs.
- Live View: Screenshots of your iOS simulator or Chrome browser on demand, via the
fetch_liveviewtool. - Log streaming: Metro bundler logs for React Native/Expo (
fetch_recent_logs) and browser console output (fetch_web_console). - Authorization policies: Block or allow specific tools per server, set rate limits, or switch servers into allowlist-only mode.
- Zero-config auto-discovery: AppContext runs at
localhost:7777and auto-connects to supporting clients.
