Site Tools in ChatGPT and Codex

In the desktop app's built-in browser, ChatGPT Work and Codex can use tools a website hands them instead of clicking through the page.

Details

Works in the desktop app's built-in browser, where the website offers the agent a set of actions it can call directly instead of the agent navigating the interface
Built on WebMCP, an open standard for websites to publish actions that AI agents can use
OpenAI is running a 10-day WebMCP hackathon with Chromium, Cloudflare, Shopify, Vercel, Render, and Netlify to get more sites publishing these tools

Best for

Letting an agent act on a site through the site's own controls rather than by simulating clicks.

When to use it

The site you work in publishes tools and you want the agent to call them directly.

Who benefits

ChatGPT Work and Codex users on the desktop app, and teams whose vendors expose these tools.
