Verify the connection

In a new chat, ask:
ChatGPT answers with your SuprSend workspaces.

​
Pin a workspace and restrict tools

By default, ChatGPT and Codex can use every workspace and tool your role allows. To keep them on one workspace, or to give them only the tools a job needs, use one of these URLs when you add the server:
  • Pin a workspace by adding its slug to the path. The agent then can’t switch to another workspace:
  • Restrict tools with ?tools=, a comma-separated list of tool names or groups:
See Scope the connection for every URL pattern, and the tool list for every tool.

​
Troubleshooting

Check the workspace slug in the URL. It must match a workspace in your SuprSend account exactly, for example staging, not the workspace’s display name. A slug that doesn’t exist fails with 403 workspace_forbidden. To see your slugs, remove the slug, reconnect, and ask: “List my SuprSend workspaces.”
