Add ui-request-render-data message type for explicit render data requests by Copilot · Pull Request #111 · MCP-UI-Org/mcp-ui

Copilot · 2025-09-23T21:08:40Z

This PR introduces a new ui-request-render-data message type that allows iframes to explicitly request render data from the host, providing a more semantic alternative to relying on the ui-lifecycle-iframe-ready lifecycle event side-effect.

Problem

Previously, iframes could only receive render data as a side-effect of sending ui-lifecycle-iframe-ready. This approach had several limitations:

It felt like an unexpected side-effect rather than an explicit request
Render data could only be requested during the ready lifecycle event
Some users experienced reliability issues with the automatic delivery mechanism
There was no way to re-request render data later in the iframe's lifecycle

Solution

The new ui-request-render-data message type allows iframes to explicitly request render data when needed:

// Iframe sends request
window.parent.postMessage({
  type: 'ui-request-render-data',
  messageId: 'optional-tracking-id'
}, '*');

// Host responds with standard render data message
// {
//   type: 'ui-lifecycle-iframe-render-data',
//   messageId: 'optional-tracking-id',
//   payload: { renderData: {...} }
// }

Implementation Details

New message type: Added UI_REQUEST_RENDER_DATA: 'ui-request-render-data' constant
HTMLResourceRenderer enhancement: Added message handling that responds with render data using the existing ui-lifecycle-iframe-render-data format
Message ID support: Properly forwards messageId from request to response for tracking
Backwards compatibility: Existing ui-lifecycle-iframe-ready behavior remains unchanged
Comprehensive testing: Added test cases for both scenarios (with and without render data)
Documentation: Updated embeddable-ui.md, resource-renderer.md, and react-usage-examples.md with detailed usage examples and alternative approaches

Benefits

Semantic clarity: Explicit render data requests vs. lifecycle side-effects
Flexible timing: Can request render data at any point, not just during initialization
Request tracking: Optional messageId support for tracking requests/responses
Reliability: Direct request/response pattern vs. automatic delivery
Backwards compatible: No breaking changes to existing functionality

Fixes #106.
