# Server settings

> The screen where an install is actually configured.

Server settings are shared by every team on the install, so only the **install owner** can open them. That
is the first account that ever signed in.

<Frame caption="Everything the server runs on, in one place. Each app is registered under your own account.">

</Frame>

<Note>
  Handing it over has no screen yet. It is one row:
  `update install_secret set value = '<user id>' where name = 'installOwnerAccountId'`, read fresh per
  request, so no restart is needed.
</Note>

## Required

Both sit under **Gus's runtime**, and Gus cannot answer anything until they are both connected.

<AccordionGroup>
  <Accordion title="OpenRouter" icon="key">
    One key that every team on this install runs on. Paste a plain inference key from
    [openrouter.ai/settings/keys](https://openrouter.ai/settings/keys).

    A **provisioning or management key will be refused**. It answers the check with a 200 and then fails
    every actual answer with `401 User not found`, so the check reads `is_provisioning_key` off the same
    payload and stops it there. A key already at zero remaining is refused too.

    The optional cap is a per-team spending ceiling in dollars, enforced before a model is called. Blank or
    `0` means no ceiling, which is what most self-hosted installs want. Because the dialog treats a blank
    field as "keep what is there", `0` is how you clear a cap you already set.
  </Accordion>

  <Accordion title="Vercel Sandbox" icon="box">
    Token, team id and project id. Gus runs its coding harness in a sandbox and has no other runtime, so
    without these the rest of the app works and Gus reports itself unconfigured.
  </Accordion>
</AccordionGroup>

## Gus in chat, and the rest

Each one is registered under your own account, so its callbacks point at your install rather than at
somebody else's.

| App        | What it unlocks                                    | Without it                                          |
| ---------- | -------------------------------------------------- | --------------------------------------------------- |
| Slack      | Gus in a Slack workspace                           | The Slack row reads "not set up on this deployment" |
| Discord    | Gus in a Discord server                            | Same                                                |
| Telegram   | Gus in a Telegram DM                               | Same                                                |
| GitHub App | Brain as Code: cloning repos, writing context back | The repo picker stays empty                         |

<Warning>
  Register the callback URLs against **your** hostname. Slack refuses an `http` redirect URL outright, so an
  install on `localhost` cannot complete the Slack setup at all. Give the server a public address first.
</Warning>

## Storage

Read-only here. `FILE_STORAGE` is set when the server starts, and files already saved keep serving from
wherever they were written.
