Troubleshooting
Resolve common Stackless MCP connection, authorization, and tool-call problems.
- The URL is rejected: confirm it starts with
https://, includes your exact workspace hostname, and ends in/api/v1/mcp/transport. - Authorization does not finish: allow browser redirects and sign in to the same Stackless workspace used in the endpoint.
- A tool is missing or denied: tool visibility and execution follow your Stackless role. Ask your administrator whether your account has the required permission.
- A request stays queued: some data operations are asynchronous. Let the agent or client check the returned operation until it succeeds, fails, or is cancelled.
For help, contact Stackless with your workspace hostname, the agent or client name, the time of the failure, and the non-secret error message. Never send an access token or session cookie.
