Build the list of tool calls
Trap some of the MCP post json based requests and map to related
handlers. Inturn implement the tool call execution handler.
Add some helper dataclasses wrt expected MCP response structure
TOTHINK: For now maintain id has a string and not int, with idea
to map it directly to callid wrt tool call handshake by ai model.
TOCHECK: For now suffle the order of fields wrt jsonrpc and type
wrt MCP response related structures, assuming the order shouldnt
matter. Need to cross check.
Will be looking at changing the handshake between AnveshikaSallap
web tech based client logic and this tool calls server to follow
the emerging interoperable MCP standard
