Connect to an MCP Server

Demonstrates Mcp.Connect, which connects to an MCP server at its Streamable HTTP endpoint URL. After connecting, the server's identifying properties are available.

Background. The Model Context Protocol (MCP) lets a client interact with a server's tools, resources, and prompts over a standard JSON-RPC interface. This example connects to the public, no-authentication Microsoft Learn MCP server at https://learn.microsoft.com/api/mcp over Streamable HTTP.
