Make your web app's tools available to agents.
Adds or repairs browser tool integrations so agents can use a web app's JavaScript logic and HTML forms.
When to use it
Use for browser WebMCP tool registration, declarative form integrations, agent-driven form handling, or Chrome preview validation, not server-side tool backends.
Give it a browser web app and an integration or debugging request; it updates the app's WebMCP implementation and validates the changes.
What you provide
Native preview execution requires Chrome 146.0.7672.0 or higher with chrome://flags/#enable-webmcp-testing enabled, running in a secure, visible window context; headless, worker, and server execution are unsupported.
