Knock

Customer messaging and notification infrastructure. Agents can search site pages, navigate, subscribe to the newsletter and open sales contact.

Ask an agent to

  • Find Knock's pages about in-app notifications
  • Subscribe me to the Knock newsletter
  • Open Knock's contact sales page

4 tools

When we loaded knock.app again on Oct 24, 2026, it registered these through navigator.modelContext or provideContext(), from earlier WebMCP drafts. Chrome 154 only offers document.modelContext, so Chrome’s own agent support does not see them.

  • navigate_to_page

    Navigate the current browser tab to a page on the Knock marketing site. Only known internal paths are accepted. Use `search_pages` first to discover valid paths.

    path: string

  • open_contact_sales

    Navigate to the Knock contact sales page so the user can talk to the sales team. This does not submit the form.

  • search_pagesread-only

    Search the Knock marketing site for pages matching a free-text query. Returns matching pages with their path, title, and description. Use this to help a user find the right page before navigating.

    query: string, limit: integer?

  • subscribe_to_newsletter

    Subscribe an email address to the Knock newsletter. The email is added to the 'newsletter-subscribers' audience. Ask the user for confirmation before calling this tool.

    email: string

Tool names and descriptions are what knock.app/ registered when we loaded it in Chrome 154 on Browser Use Cloud. The summary and the “ask an agent” lines are AI-written from them. To call the tools yourself, see Chrome’s WebMCP docs. How we found it.
