Codex Control Chrome MCP

Expose the Codex Chrome extension flow to other Agent tools through MCP.

• NPM: codex-control-chrome-mcp

• GitHub: iola1999/codex-control-chrome-mcp

• Chrome Extension: Codex Chrome Extension

• Skill: skills/codex-control-chrome-mcp/SKILL.md

Current implementation is an early Node.js prototype with:

• official @modelcontextprotocol/sdk stdio server

• Chrome Native Messaging host mode

• MCP stdio server mode

• install/uninstall commands with manifest backup

• JSON-RPC bridge socket under /tmp/codex-browser-use

• basic Chrome tab/CDP MCP tools

Install the Chrome native host:

npx -y codex-control-chrome-mcp@latest install-native-host

The user must also have the Codex Chrome Extension installed and enabled in the Chrome profile they want to automate.

Uninstall and restore the previous Codex native host manifest:

npx -y codex-control-chrome-mcp@latest uninstall-native-host

Intended Agent config:

{
  "type": "stdio",
  "command": "npx",
  "args": ["-y", "codex-control-chrome-mcp@latest", "--stdio"]
}

If your Agent supports skills, install or reference the bundled skill folder:

skills/codex-control-chrome-mcp

The skill documents the recommended MCP tool order for status checks, tab claiming, CDP commands, screenshots, events, and tab finalization.
