What to check first
For this issue, start with the active workspace and the relevant settings screen. Tell the team which operations and authentication you need. Read the current confirmation or provider error rather than repeating the action immediately. Keep a record of what you tried and its approximate time so an administrator or the support team can identify the request.
Choose a connection method
The custom integration chooser offers the methods enabled in your workspace. A remote MCP server exposes tools through its own endpoint. An API connection describes an HTTP service and the authentication it requires.
Verify the service
Use an endpoint you trust and control, or one whose operator your team has approved. Review the tools it exposes and the data it can receive. A custom tool's description is supplied by its operator; it is not a workspace permission grant.
If the issue remains
Open the custom integrations guide for the current product steps. If that does not resolve the issue, contact support. Include your workspace name, the screen, and the approximate time. Do not send passwords, API keys, card numbers, or an unrestricted data export.
