Error: The connection cannot be authenticated.
Check that you are using the exact endpoint URL provided by Criteo, including the MCP path. For a standard connection, select OAuth. For a key-based URL, select None or No sign in — the credential is already included in the URL.
Error: The connector is not available in Claude (Team or Enterprise plan).
An Owner or authorized administrator must add the connector to the organization before individual users can connect. For Pro or Max plans, add the connector yourself from Settings → Connectors.
Error: The connector is not available in ChatGPT.
Ask your workspace administrator to confirm that Developer Mode or the custom MCP connector setting is enabled, then check the current OpenAI documentation for plan and workspace requirements.
Error: The returned accounts are not the expected accounts.
Do not continue using the connection. Contact your Criteo representative to verify which accounts are enabled for your connection. If you need access to specific accounts only, ask about a key-based connection.
