[enhancement] Show expected format from MCP tool inputSchema

[shapkarin]

Problem

When debugging MCP tools in MCP Inspector, the tool form renders fields from inputSchema, but the UI does not expose the data type and validation from the schema. This makes it hard to debug whether the MCP server is exposing a good schema for agents/clients.

Why this matters

The inputSchema is the main contract an MCP agent uses to understand how to call a tool correctly.

I'm bumping into this as well. Please show us - in JSON or otherwise - what the agent actually sees in terms of schema information. I'm having a really hard time figuring this out right now.
