Devloop

What is Devloop?

Devloop is an MCP server that drives a browser or a native Expo/React Native app (iOS/Android) alongside your dev server, placing both on one correlated timeline. It is built for Claude Code, AI agents, and human developers.

How to use Devloop?

Install by running claude mcp add devloop --scope user -- npx -y devloop-mcp or by adding the JSON config with command: "npx" and args: ["-y", "devloop-mcp"] to your mcpServers block.

Key features of Devloop

• One timeline for server stdout/stderr and browser console/network/page-errors.
• Drive Chrome, Expo, or React Native apps on iOS simulator or Android emulator.
• Run action sequences (navigate, click, type, eval) and get repro with network idle.
• Unified query API: get_logs, get_logs_around, get_network, export_har, diagnose.
• Per-app scoping with a shared daemon supporting multiple projects over HTTP/SSE.
• Electron cockpit with tabbed browser panes, timeline, element picker, repro builder.

Use cases of Devloop

• Correlating a browser console error with the backend stack trace from the same moment.
• Recording a user action sequence (navigate, click, type) to reproduce a bug.
• Debugging cross-stack issues in projects that combine a dev server and a client app.
• Running multiple agent workflows simultaneously with a shared daemon and HTTP/SSE.
