FormBuilderProcessorWebMCP

[psy]

FormBuilder WebMCP is an alpha FormBuilder action that lets a visitor’s compatible AI assistant prepare a form using information the visitor provides.

The assistant can place the answers into the ordinary form, where the visitor can review and edit them. By default, the assistant is asked to leave submission to the visitor. The WebMCP action itself does not submit the form; FormBuilder remains responsible for validation and any subsequent entry storage or email.

The module is currently best suited to single-page forms. Multi-page forms need further work before they can be recommended. WebMCP also depends on the visitor having a compatible browser and assistant. The form continues to work normally when WebMCP is unavailable.

How is this different from FormBuilder GPT-Live?

Both actions can help a visitor prepare a FormBuilder form while providing help in different ways:

• FormBuilder GPT-Live adds a voice assistant to your website. The visitor speaks with the assistant provided by the site, which helps prepare the form. The site owner configures the AI service and is responsible for its API usage and costs.
• FormBuilder WebMCP makes a form preparation tool available to the visitor’s own compatible assistant. The site does not provide the AI assistant; the visitor uses whichever compatible assistant they already have access to. Any account or usage costs depend on the user's assistant.

For example, with GPT-Live a visitor might start a voice conversation on your website. With WebMCP, they might ask their own compatible assistant to help fill in the form while it is open.

What is WebMCP?

WebMCP is an experimental browser technology that allows a website to describe tools and their inputs to compatible AI assistants. For this module, the tool describes the form fields that an assistant may prepare.

The WebMCP specification is a draft published by a W3C Community Group, and browser and assistant support is still developing. Chrome has offered an origin trial and developer testing options; availability depends on the particular browser, assistant and setup.

Trying it out:

WebMCP support is still developing. One way to try the module is with site tools in the ChatGPT desktop app’s built-in browser, where available for your account and selected model. Developers can also explore it in Chrome using its WebMCP testing flag and tools

I’d welcome feedback from anyone experimenting with WebMCP, particularly on different form fields, browser and assistant combinations, and any issues you encounter. Please keep in mind that this is an alpha release and multi-page forms need further work.
