Set up Turn Zero in the Claude desktop app #

View this page as Markdown

Use a custom connector for Claude desktop chat and the Code tab. The same connector is available on claude.ai. 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 desktop app or hasn't named a Claude surface, offer both routes in the same approval message. The connector starts sign-in from Claude settings. Terminal setup starts sign-in in terminal Claude Code and can serve new Code tab sessions.

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.

The person follows these steps in the Claude desktop app.

  1. Open Settings → Customize → Connectors → Add → Add custom connector.
  2. Enter turnzero and paste the address into MCP server URL. Choose Continue.
  3. Keep Sign in now, choose Register automatically under OAuth client, and leave Request headers empty.
  4. Choose Add. The person completes browser sign-in and chooses Allow access if asked. Keep tokens and callback URLs out of chat.
  5. In desktop chat, open + → Connectors and turn on turnzero. In the Code tab, look for the connector by name or ID. Its instructions identify it as Turn Zero. If it doesn't appear in the current Code tab session, open a new one and check there.

If you already added turnzero from a terminal and want to switch to the connector, run claude mcp remove turnzero before adding it. Keep one connection. If you picked the wrong authentication option, remove the connector and add it again.

On a Team or Enterprise plan, an owner adds the connector under Organization settings → Connectors, then each member chooses Connect.

Check the connection #

Paste this into the chat or Code tab where you enabled the connector:

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.
