I’m seeing the same issue as a third ChatGPT user. I have an active Premium Archive subscription and tested the connection through ChatGPT Developer Mode.
I tried both endpoints:
-
https://newsblur.com/mcp -
https://newsblur.com/mcp/
ChatGPT correctly discovers Dynamic Client Registration (DCR), reports that CIMD is unavailable, and discovers the following scopes:
-
read -
write -
mcp
I also tried explicitly adding all three as base scopes before creating a new connector. The result is still the same:
There was a problem connecting NB Test. Try again later.
The OAuth connection does not complete, and no MCP actions are discovered. This appears consistent with the earlier callback error stating that the client was not registered with the read scope.
Could you please check whether the DCR registration endpoint is saving and allowing the requested read, write, and mcp scopes for newly registered ChatGPT clients?
