1-line autonomous agent setup instruction. Paste into Claude Code, Codex CLI, or Cursor Agent:
Fetch and configure Model Context Protocol (MCP) server Chrome DevTools from https://www.fastmcp.dev/server/chrome-devtools
Agents automatically discover, install, and execute the server spec without manual token setup.
Connect via direct Stateless MCP v2 / Streamable HTTP endpoint or JSON-RPC:
https://github.com/chromedevtools/chrome-devtools-mcp
Stateless edge endpoint compliant with MCP 2024-11-05 and v2 draft protocol specs.
Includes server instructions and tool definitions for Claude:
claude mcp add chrome-devtools -- npx -y chrome-devtools-mcp@latest
Run in terminal to register server in current project or pass --scope user for global availability.
Configures server instructions and tools for OpenAI Codex & ChatGPT Desktop:
[mcp_servers.chrome_devtools]
command = "npx"
args = ["-y","chrome-devtools-mcp@latest"]
