If you already use a Stremio add-on (a manifest URL), you can paste it into MIRA. It becomes one more source in the same resolve ladder as debrid and IPTV. You do not need the Stremio app open.
Copy the add-on manifest URL you already use (it usually ends in manifest.json).
Open miraplayer.tv/account → Sources → Stremio add-on.
Paste the URL and save. MIRA checks it can read the manifest before storing it.
Play a title. If debrid or IPTV already has a better file, that still wins. The add-on is a fallback, not a second app to juggle.
Pair with IPTV and TorBox / Real-Debrid. Search layer: Jackett.
