Codex 新增 WebMCP 支持，为网站添加 Agent 工具

Codex has been able to use the web for a while now and watching it click around never gets old. But one thing that is annoying is that it's quite slow. We're releasing WebMCP support in Codex and what that lets you do is just add tools straight into your website and it lets Codex go ahead, pull it down and figure out exactly the capabilities that it needs to know about to make really great results on your website. I've put together a little demo called Codex Modeling Studio and it lets Codex open the website and just visually iterate on a 3D model that you can even 3D print after.

It's able to set up shapes, take screenshots from different angles without interrupting your view and we can kind of collaborate Codex and I on the demo and I can give it notes as it works. It's a little demo just to show off the capabilities of something like pretty advanced that you can put in a website. You know, sites are not just for, you know, simple eShop pages you can actually have full 3D renderings and all kinds of things going on there and having WebMCP just really elevates the possibilities of what you can show and distribute to people.

Adding WebMCP to your site is just as easy as asking Codex to do it. It can go ahead, figure out the spec and write the tools for you. What I recommend is that you spend some time dogfooding, iterating with Codex. Codex is your customer. It's the one using the tools, not the user. So you want to make sure that tools are discoverable to it and it knows exactly what it needs to do. You can spend some time trimming down your tool set making sure the descriptions are clear and it's able to get to where it needs to go as efficiently as possible.

Codex will tell you if you ask it for feedback and I've even added a feedback tool in the demo here. So as Codex works it can flag errors and let me know when there's something that needs fixing. It's a very different world to build tools for a model versus having them be for a person but we're in this world now where models and people can collaborate on the same interface with different channels and it's a very different experience but it's a whole new world having Codex build tools for itself and being able to iterate on visuals alongside you as you see something different than it does.

I'm just starting to scratch the surface of what's possible to build now that agents can interact with sites independently of you, and I'm really excited to see what you all build.
