# Set up Turn Zero in terminal Claude Code

Before adding or changing a connection, check whether `start` already works. Reuse a working `turnzero` connection. Ask once before changing the setup. If the person uses the Claude desktop app or hasn't named a Claude surface, offer both routes in that message. This route starts sign-in in terminal Claude Code. The [custom connector](/tztrack/getting-started/set-up-claude-desktop/) starts sign-in from Claude settings and covers desktop chat, the Code tab and claude.ai.

For a new tzTrack and tzMesh connection, use `https://turnzero.ai/mcp?products=tztrack,tzmesh`. Use `https://turnzero.ai/mcp` if you need tzCloud. The plain address turns on every product your account has. The query can only narrow that set, and a saved selection overrides the address.

On an existing connection, use `choose_products` to turn on `tzcloud`, `tztrack` or `tzmesh`. Pass every product you want to keep on. Image generation uses tzCloud. Call `create_application` before `generate_image`, which saves the image in the application's storage.

1. After approval, you or the person can add `turnzero` from a terminal. The user scope makes it available across project folders. If you chose the plain address, use it in the command.

   ```text
   claude mcp add --transport http --scope user turnzero "https://turnzero.ai/mcp?products=tztrack,tzmesh"
   ```

2. The person opens a new interactive terminal session with `claude`, types `/mcp`, and chooses `turnzero`. The person completes browser sign-in and chooses **Allow access** if asked. Keep tokens and callback URLs out of chat.
3. Run `claude mcp get turnzero` after sign-in. Look for **Connected**. This also shows the full saved address, including the query string that `claude mcp add` may omit.

The session that added the server cannot load the new tools. Report the tool check as pending and give the person the prompt below. In a Claude Code 2.1.316 macOS test, a new desktop Code tab session loaded the user-scoped tools after terminal sign-in, even though the desktop app's `/mcp` settings did not list the server.

To switch to the custom connector, first remove the terminal entry with `claude mcp remove turnzero`. Keep one connection.

## Check in a new session

Open a new terminal or desktop Code tab session and paste:

```text
Check my Turn Zero connection. Call start and tell me which products are on. If the call fails or is unavailable, tell me what happened.
```
