feature: RAW JSON schema in MCP client

[lmorg]

Problem Statement

I'm running an MCP client using this library, and it mostly works really well. However getting the LLM to speak the same language (ie pass the right parameters) to the MCP servers is proving a little tricky.

I can see the MCP client does have a Go struct that's created from the MCP server schema, but I'd like the raw schema that's sent from the server when joining tools so that i can forward to the LLM

Proposed Solution

Just a []byte with the raw JSON that was sent from the server
