Fix MCP server support using MCPStreamableHTTPTool

[Copilot]

The commented-out MCP server code used a non-existent agent.add_mcp_server() method. Updated to use the correct MCPStreamableHTTPTool class for remote HTTP-based MCP servers with real-world examples.

Changes

• Import: Added MCPStreamableHTTPTool from agent_framework
• Tool creation: Replaced invalid add_mcp_server() calls with proper MCPStreamableHTTPTool instantiation
• Real-world examples: Added two practical MCP server examples:
  • Microsoft Learn MCP server (HTTP)
  • GitHub MCP server (HTTP with OAuth)
• Simplified usage pattern: Users uncomment the async context manager line and the tools=mcp_tool parameter (no code duplication)
• Documentation: Added "Using MCP Servers" section to README with step-by-step setup instructions

Examples

Microsoft Learn MCP server:

mcp_tool = MCPStreamableHTTPTool(
    name="learn-mcp",
    url="https://learn.microsoft.com/mcp",
    description="Microsoft Learn MCP server"
)

GitHub MCP server with OAuth:

mcp_tool = MCPStreamableHTTPTool(
    name="github-mcp",
    url="https://api.github.com/mcp",
    headers={"Authorization": f"Bearer {os.getenv('GITHUB_TOKEN')}"},
    description="GitHub MCP server"
)

Usage:

# Uncomment these lines to enable MCP tools:
async with mcp_tool:
    agent = ChatAgent(
        chat_client=chat_client,
        instructions=instructions,
        tools=mcp_tool  # Uncomment this parameter
    )
    result = await agent.run("Your message")

This follows the official Agent Framework pattern for remote MCP servers over HTTP/SSE.

<issue_title>Improve MCP server support</issue_title>
<issue_description>There is a commented out section of code showing optional ability to run the agent with MCP server tools passed in. It is not correct.

Please update this sample in simplest possible way to enable remote MCP servers to pass in their tools to the agent. use the learn example from this document: https://learn.microsoft.com/en-us/agent-framework/user-guide/model-context-protocol/using-mcp-tools?pivots=programming-language-python

@copilot The optional code repeats too much of the while True: loop. Can't we just have the user uncomment the line with tools=mcp_tool?

Also, use two real examples of servers and tools to add:

• Microsoft Learn MCP (http)
• GitHub MCP (http using oauth)

Simplified the code to avoid repeating the while loop. Users now just uncomment two lines: the async with mcp_tool: line and the , tools=mcp_tool parameter.

Updated with two real examples:

• Microsoft Learn MCP server (HTTP)
• GitHub MCP server (HTTP with OAuth using GITHUB_TOKEN env var)
