Question

When a user uploads a file on chatGPT interface, I want it to trigger a MCP Tool that processes the file and then return a new output file to the chatGPT interface for user download.

How to handle user file inputs/outputs in MCP python? Is it documented somewhere?

Thank you for your answers

Maybe you don't understand what MCP is? Your requirement here is to tell LLM to pass the files uploaded by users to a certain MCP tool, and then provide the files returned by MCP for users to download.
