    "note": "Two APIs are live. (1) Declarative: HTML forms are annotated with toolname / tooldescription and individual fields with toolparamdescription. (2) Imperative: two tools are registered with navigator.modelContext.registerTool and carry a typed inputSchema, so an assistant can pass content as text instead of attaching a file. Browsers that do not implement WebMCP ignore both, so this is a progressive enhancement. Activation in Chrome requires the WebMCP origin trial (or the local flag chrome://flags/#enable-webmcp-testing).",
