Does MCP client support output schema?

I like Postman, so this is good to see that MCP is supported. But I am missing the output schema of MCP tool. Is it supported? It it visible?

Hi @ing.karel.kral :waving_hand:. Welcome to the Postman Community :postman:

We currently do not display the output schemas of the MCP tool; we provide a nice UI with input fields for the input schema instead. Curious to know what your use case for having the output schema in the product is. Is it just for visual introspection, or do you have specific workflows that need to be supported?

I am developing MCP server with structured output. PostMan after executing tool reported an invalid output according to schema. But where to see output schema to compare? I have to go to MCP inspector, and there is an output schema. Then I can recognize some mismatches between the schema and data and solve it.
MPC server is from dotnet 10.
