Update: solved on my side.
The problem was how I had paired Clave with my MCP server: I used a nostrconnect link. Pairing through a bunker address (copied from Clave) instead fixes it, even from Termius on the same iPhone: with Clave in the background and low trust, the connection resumes by itself and the signing request arrives so I can approve it (about 6 seconds).
Tested once so far, but it worked exactly in the setup that failed before. In case it helps ⚡️ᗪㄖ匚⚡️ (npub1xy5…3urc) or anyone with the same setup. Clave (npub1cla…539g)
