Bug type
Generation bug (slides/content incorrect)
Summary
I use presenton MCP in openwebui (v0.6.33). Don't generate presentation.
Comfyui works ok.
Custom LLM works ok.
I have only trouble with MCP.
Maybe, do i need to try openapi?
My settings:

Steps to reproduce
- Add extra connection tool in openwebui by MCP
- Add new tool to model in workspace
- Send message "Generate presentation about detail A.S. Pushkin in russian" to model
- Raise error in presenton
Expected behavior
The presentation should export successfully as a PPTX file.
Actual behavior
