Build structured tools for agents to complete tasks efficiently and accurately in your web application with WebMCP.

In Chrome 149, you can sign up for the WebMCP origin trial. If you are new to origin trials, these are time-limited programs that offer early access to experimental platform features. While there may be usage limits, developers can integrate these features for live testing and gathering user feedback, with the goal of informing future iterations of the API.

What is WebMCP?

WebMCP lets you provide rules for interaction between web applications and agents. Instead of an agent guessing the purpose of an interface element, such as a button or input field, you can declare their purposes and manage page state.

Use cases

There are many ways to add WebMCP to your website. For example:

• Correctly fill in complex, structured forms: Build a WebMCP tool to help users map data to fields correctly, instead of relying exclusively on autofill. For example, you can differentiate if a field requires a full name versus a separate first and last name.
• Efficient application debugging: Build a diagnostics tool on a developer settings page, so an agent can trigger fixes that are otherwise hidden behind nested menus.

You can also help an agent understand interfaces that are designed for humans, such as calendar inputs.

Is your use case missing or do you have an idea you're excited about for WebMCP? Join the early preview program and share your feedback.

Build your website for the agentic era

At Google I/O 2026, we shared how you can prepare your websites to help agents perform tasks efficiently.

Share your feedback

Our goal is to build APIs that any browser with agentic capabilities can implement and benefit from. Read the WebMCP documentation, includingbest practices andtool security guidance.

• Join the origin trial
• Share your feedback on the API shape by commenting on an existing issue or opening a new one in theWebMCP explainer on GitHub.
• If you have feedback on Chrome's implementation, file aChromium bug.
• Join the early preview programfor an early look at new APIs and access to our mailing list.
• Review the implementation for Chrome onChrome Status.
