**Requirements:** Admin role; an API key from the provider, ideally with the minimum permissions its info sheet indicates (section 4). 1. On the template's card, tap **Connect**. 2. Paste your **key** — it's never shown again after you submit it. 3. Read the notice "You're connecting this service under your own responsibility…" and tick the **"I have read and accept this notice"** checkbox (required). 4. Tap **Connect and test**. **Result:** we actually try to connect with the key you provided. If it's invalid, you see the real error and nothing gets saved: If the key is valid, you move to the second step, **"Turn on what the assistant will be able to use"**: the full list of tools that server exposes, **all disabled** by default ("All tools start disabled. Turn on only the ones you need — you can change this later."). Turn on, one by one, the ones your agent is going to need and tap **Save** — or **"Not now, leave everything off"** if you'd rather decide later (the connection is made either way, just without any tool active yet).
