Describe the problem/error/question

Using Qdrant function “retrieve documents (As Tool for AI Agent)”
This works when directly connected to an agent.
However, when connected to an Tool AI agent, I get an error.

What is the error message (if any)?

Error: The Tool attempted to return an engine request, which is not supported in Agents

I have a AI Agent with a mcp tool that works. If I try to add in between an AI Agent Tool, I get the exact same error. If I remove the mcp tool from the AI Agent Tool, the error disappears, but no tool is executed of course.
