aio-cdp-relay

Persistent Chrome DevTools Protocol relay for Claude Code. Interact with Chrome browser via scripts — no MCP tool calls needed, no approval prompts per action.

Install

/plugin install aio-cdp-relay@aiocean-plugins

How It Works

A lightweight HTTP relay process maintains a single WebSocket connection to Chrome. Scripts talk to the relay via http://127.0.0.1:9223 — the relay forwards CDP commands and buffers events. Auto-starts on first use, auto-terminates after 5 minutes idle.

Script ──HTTP──▶ CDP Relay ──WebSocket──▶ Chrome
Script ◀─HTTP── CDP Relay ◀──WebSocket── Chrome

Why

• No MCP approval prompts — scripts use HTTP, not MCP tools
• Single connection — relay holds one WebSocket, scripts connect/disconnect freely
• Scriptable — write reusable Python scripts that interact with the browser
• Auto-lifecycle — starts automatically, dies after 5 min idle

Requirements

• Chrome with remote debugging enabled (chrome://inspect/#remote-debugging)
• python3
• websocket-client (pip install websocket-client)
