Troubleshooting
The client cannot reach StackYapper
Confirm the endpoint first. ChatGPT uses
https://mcp.stackyapper.dev.
Claude, Codex, and most other clients use
https://mcp.stackyapper.dev/mcp.OAuth keeps looping
Remove the StackYapper connection from the AI client, add it again, and
complete a fresh sign-in. Check that the expected workspace is shown on the
StackYapper consent page.
The client is connected but tools are missing
The user may not have an app or tool grant. Ask a workspace administrator
to check Apps and Users & Groups in the portal.
An app says it needs attention
Its provider credential may have expired or been revoked. Reconnect the app
from the StackYapper portal.
An operation asks for confirmation
StackYapper requires confirmation for approved risk classes. Review the
proposed operation carefully. The confirmation is bound to that operation.
Still blocked?
Capture the client name, approximate time, active workspace, and the exact error
message. Do not include provider secrets, OAuth tokens, or MCP API keys.
