Module client 

MCP Client — connects to external MCP servers and invokes tools.

Supports two transports:

• stdio: spawns a child process, communicates via JSON-RPC over stdin/stdout.
• http: sends JSON-RPC requests over HTTP POST (Streamable HTTP transport).

The client performs the MCP initialize/initialized handshake, discovers tools via tools/list, and invokes tools via tools/call.
