Mobius

Streams browser console/network events to a local mobius-mcp server for AI coding agents. Click the icon to enable capture on a tab.

Mobius connects your browser to your AI coding agent. If you use Claude Code, Codex CLI, Gemini CLI, Cursor, or any other MCP-compatible AI agent to build web apps, you've probably copy-pasted console errors or network responses into chat so the agent can see what's happening. Mobius removes that step. Install the MCP, then Click the toolbar icon to enable capture on a tab, and your agent can instantly see: * Console logs, warnings, and errors * Network requests and responses * Page navigation, including SPA route changes * Screenshots and the live DOM It can also help your agent act on what it sees — reload the tab, navigate to a URL, run JavaScript in the page, or profile CPU/memory — the same way Chrome DevTools does, except your agent drives it directly instead of you narrating what you see. Why this instead of automated browser testing tools? Most AI browser tools drive a headless or automated browser. Mobius instead watches the tab you're already using — so you can click around, fill out a form, or trigger a bug yourself, in real time, while your agent watches the same events happen and helps you fix them on the spot. Everything stays local. Mobius only talks to a small MCP server running on your own machine (mobius-mcp, open source, published on npm). Nothing is sent to any cloud service, and nothing runs until you explicitly enable it on a tab. No account, no telemetry, no ads. Getting started 1. Install the free mobius-mcp MCP server: npx mobius-mcp (or claude mcp add mobius-mcp -- npx -y mobius-mcp for Claude Code) 2. Click the Mobius icon and enable capture on the tab you're working on 3. Ask your agent to check the console, network requests, or DOM — no more pasting logs into chat Repository: https://github.com/Topman-14/mobius-mcp
