MCP Transports, Lifecycle, and Advanced Capabilities

Choose the right MCP transport and reason about initialization, sampling, and roots.

What you will be able to do

✓Select the correct transport for local (stdio) vs remote (Streamable HTTP) MCP servers and know it replaced HTTP+SSE
✓Identify JSON-RPC 2.0 as the MCP wire format and describe the initialize capability-negotiation handshake
✓Explain sampling: a server requesting an LLM completion from the host, with a human-in-the-loop checkpoint
✓Explain roots as client-declared filesystem boundaries that scope a server under least privilege
