ChatGPT Site Tools: WebMCP for Interactive Websites

OpenAI has added WebMCP support to the built-in browser in its ChatGPT desktop app. This new feature, called site tools, allows compatible websites to offer structured actions directly to ChatGPT Work and Codex. Here's the thing: when a suitable tool is available, ChatGPT can automatically recognize and use it without needing a separate connection. Site tools can help with tasks like searching documents, editing files, exploring dashboards, or updating shopping carts. What's interesting is that an arrow appears in the address bar when these tools are available, indicating if they can read data or make changes. This is different from ChatGPT's standard browser use, which relies on clicking and typing. WebMCP allows developers to define exactly how an AI can use their app by registering JavaScript functions as tools. The bottom line: this experimental open standard aims to make AI interactions with websites more precise and efficient, but it requires GPT-5.6 Sol or Terra and is not available in Enterprise or Edu workspaces.
