Very interesting, one big wrinkle with OP:s approach is exactly that, the structured responses are un-touched, which many tools return. Solution in OP as i understand it is the "execute" method. However, im building an MCP gateway, and such sandboxed execution isnt available (...yet), so your approach to this sounds very clever. Ill spend this day trying that out
