Yes. UI Exo MCP only lists/searches/reads prompts and the catalog. No shell, no meetings, no file writes.
Use Method 1 (paste MCP URL + OAuth) or Method 2 (Authorize button → login if needed → consent).
OAuth reuses your PHP session. You only confirm consent — no second password prompt.
Organized under app/data/prompts by category, with CATALOG.md and index.json generated by PHP.
