What's Wrong?

Every call to the kie-ai MCP connector's prepare_media_generation tool returns "approved": false, "reason": "Host declined the approval request." No
approval prompt is ever shown to the user on the Desktop app. This happens 100% of the time regardless of account credit balance.

What Should Happen?

The tool should either show the user an approval prompt (elicitation) before spending credits, or the connector should work the same way it does on the CLI, where this approval flow is supported.
