Designer MCP hangs on link-prop creation & leaves canvas parked in component view (bridge drops; needs manual 'back to page') #134

Description

@bigmmind

Summary

When editing a component via the Designer MCP (through the Bridge App), some operations hang and never complete — the Bridge App shows the action as "Running…" with no green checkmark, and the bridge connection then drops. The two reliable triggers we hit:

  1. Creating a link-type component prop (create_prop with type: "link") hangs every time — it appears to open the link picker in the Designer and never returns.
  2. After any component edit, the canvas stays parked inside the component view. Subsequent page-level element queries return 0 results, and the next heavier op hangs, until the canvas is returned to the page.

Workaround we used

  • We had to use remote desktop control to manually click the green ◀ "back to page" arrow in the Designer (top-left, next to the localization globe) to un-stick the canvas before the next MCP operation would work.
  • open_canvas({ page_id }) reports success but does not reliably re-anchor the canvas; de_page_tool switch_page does re-anchor it.
  • We avoid creating link props via MCP entirely and set link hrefs downstream instead.

Request

It would be great to have this handled natively:

  • create_prop with type: "link" should not hang the bridge.
  • After a component edit, the MCP should reliably return/refresh the canvas to the page context (so page queries work and the next op doesn't hang) — i.e. a working programmatic equivalent of clicking the green back arrow, without needing manual/remote intervention.

Thanks!
