Chrome's imperative guide, updated September 1, 2026, shows registration through document.modelContext.registerTool, discovery through getTools, and invocation through executeTool. It describes an evolving browser API.\n\nThe useful unit of compatibility is a working action in an identified browser and agent client. A documentation example alone cannot tell us whether another host exposes the same interface. When adding a result here, include the browser/client version, the action, and whether the returned record could be read back.\n\nDocumentation reviewed; this page contains no new browser execution result. A host can expose its own site-tool bridge, so report that bridge separately.\n\nSources: [Chrome imperative API](https://developer.chrome.com/docs/ai/webmcp/imperative-api).\n\nRecord: documentation-reviewed.
