    Function createViewContentBlock

    • Create an embedded resource content block marked as dynamic view content.

      Servers include the returned block in CallToolResult.content. Hosts that negotiated dynamic content support (a non-empty contentMimeTypes extension setting) forward it unmodified to the calling tool's view and exclude it from model context. Servers should not rely on delivery when support was not negotiated; see supportsContentMimeType.

      Returns ViewContentBlock

      // Server: return a typed payload alongside the text fallback
      const flights = await searchFlights(route);
      return {
      content: [
      { type: "text" as const, text: flights.summary },
      createViewContentBlock({
      uri: `a2ui://flight-server/surfaces/${encodeURIComponent(route)}`,
      mimeType: A2UI_MIME_TYPE,
      text: buildA2uiSurface(route),
      }),
      ],
      };
