# Your team's connections

A team can connect apps of its own, such as an attendance system or an ERP. Each one is
a server your team runs, which its people's assistants can use. The people it is for find
it in their assistant's list of connections, with no second sign-in.

The **Connections** tab is for the team's leaders only. Building an app is described in
[Apps for your team](/developers/apps).

## Adding an app

1. On **Connections**, press **New connection**.
2. Give it a **Name**, as people will see it in their list.
3. Give its **Address**: where the app's MCP server answers, starting with `https://`.
4. Under **For**, choose **Everyone**, or **Chosen roles** and tick the roles.
5. Press **Save**.

The dialog then shows the app's **App ID**, with **Copy**. Give it to whoever runs the
app: the app uses it to accept only what Theorem made for it. It is not a secret.

| Rule | Limit |
|---|---|
| Apps in a team | 25 |
| A name | 1 to 40 characters, as a team's name, and unique in the team |
| An address | `https://` and a host name with a dot, no user name, password or `#` part, 300 characters at most |

## The check

Each time you save, and each time you open an app, Theorem checks it: it connects as you
and lists the app's tools. You see **Checking…**, then either:

- **Connected.** and the tools found, each marked **asks first** or **runs freely**: whether
  the assistant asks people before it uses that tool; or
- what went wrong, in plain words, with **Check again**. The list of apps then says **Not
  answering** beside it while you stay on the page.

What each problem means, and what to do, is in [Problems and what to do](/developers/problems).
One person can check 10 times a minute.

## Who gets an app

- **Everyone:** every member of the team, leaders too.
- **Chosen roles:** whoever holds any of the ticked roles. A leader gets it only by holding
  one of them, like anyone else. A leader can still check it.

Who gets it is worked out each time a person writes to the assistant. A person who joins
a role has the app from their next message. One who leaves the team or the role no longer
gets it from their next message, and no new token is made for them: the last one they were
sent ends within five minutes.

If every role an app was for is deleted, the app is for **No one** until you change it.

## Editing and deleting

Open an app from its row, or choose **Edit** in its menu, to change its name, address or
who it is for. **Delete** in the menu asks first, and says how many people stop getting
it. Your app's own server is not changed.
