Connect Siglata to [ChatGPT](https://chatgpt.com) on the web, as an app for your own MCP server. ChatGPT requires developer mode, available on the Plus, Pro, Business, Enterprise and Edu plans. To use Siglata in Codex, see [Connect Codex](/docs/en-US/agents/install/codex).

## Steps [#steps]

1. In ChatGPT, open **Settings**, then **Security and login**, and turn on **Developer mode**.
2. Open **ChatGPT Plugins** and click the plus button to create an app.
3. Name the app, for example `Siglata`, and paste the server address:

   ```text
   https://www.siglata.com/v1/mcp
   ```

4. Under authentication, choose **OAuth** and create the app. ChatGPT opens the Siglata sign-in.
5. Sign in to Siglata, choose the organization and approve access.

In a conversation, choose **Developer mode** in the plus menu and select the Siglata app.

In a Business, Enterprise or Edu workspace, an admin may need to turn on developer mode, under **Workspace settings** and **Apps**, and publish the app for other members.

## Approvals [#approvals]

Tools that change files, folders, sharing or members ask for confirmation before each call. Only choose to remember the approval if you trust the app.

## Done [#done]

Setup is complete when ChatGPT authenticates with Siglata. Keep working in the conversation and [add files](/docs/en-US/workspace/files) when you need them.

## Troubleshooting [#troubleshooting]

- **Wrong organization.** Remove the app, create it again and choose the right organization at sign-in.
- **No tools.** Open the app's details in settings and refresh the server.
