Agent readiness check

The page registers WebMCP tools

The page registers tools for in-browser agents through document.modelContext (WebMCP).

Run this check on your site

Runs just this check in quick mode. The report opens with the evidence and the fix.

Why it matters

WebMCP lets an agent that is already on the page call the site's functions directly, instead of clicking through the interface and reading the screen.

How to fix it

Register the page's main actions with `document.modelContext.registerTool({ name, description, inputSchema, execute })`, guarded so browsers without WebMCP skip it.
