Open **Settings → Setup & keys**. It has six tabs:

| Tab | What it's for |
| - | - |
| **Needs** | Everything the app still requires before a feature works, with a to-do count. |
| **App settings** | Ordinary choices, like the admin email. |
| **API keys** | Private keys, stored encrypted and never shown to your app's users. |
| **Webhooks** | Endpoints your app receives on, with an end-to-end test. |
| **Database access** | Your app's own database address and key. |
| **MCP** | Servers that give the build agent live docs and tools. See [MCP servers](/builder/mcp). |

## Webhooks

When another service needs to notify your app — a payment succeeded, a form was submitted — the Webhooks tab shows the address to use and lets you send a test.
