[BUG] Azure MCP Server should support Azure Arc (hybrid/multi-cloud)

[ver567]

Describe the bug

When attempting to deploy the provided Azure MCP Server Docker image to AWS Bedrock AgentCore runtime, we encountered two blocking issues:

1. Wrong Architecture: The Dockerfile builds for AMD64 by default, but AWS Bedrock AgentCore only supports ARM64. The build completes but the runtime fails to start on AgentCore.

2. Hardcoded Endpoint Path: The source code has the endpoint hardcoded to root /, but AWS AgentCore expects MCP servers to expose endpoints at /mcp. This requires modifying the source code, making it painful to maintain and update.
   Additional context
   We successfully deployed after:

3. Rebuilding for ARM64

4. Modifying source code to use /mcp endpoint

5. Setting required environment variables

However, this creates maintenance challenges:

• Can't easily update to new versions (source code patches needed)
• Requires forking or manually tracking changes
• No clear guidance for cloud deployment vs local development

Making architecture and endpoint path configurable would enable deployment to cloud platforms without source code modifications.

Expected behavior

We expected to:

1. Build the provided Docker image for ARM64 architecture (AWS AgentCore requirement)
2. Deploy to AWS Bedrock AgentCore without source code modifications
3. Have the server automatically expose the correct /mcp endpoint
4. Connect using standard MCP clients

Actual behavior

Issue 1 - Architecture Mismatch:

• Dockerfile builds for AMD64 (default platform)
• AWS AgentCore only supports ARM64 containers
• Container fails to start on AgentCore due to architecture mismatch

Issue 2 - Endpoint Path Hardcoded:

• Source code hardcodes endpoint to root /
• AWS AgentCore expects MCP servers at /mcp endpoint
• Required modifying source code to change endpoint path
• This creates maintenance burden - can't easily update to new versions without re-applying patches

Reproduction Steps

Architecture Issue:

1. Build Docker image without platform specification: docker build -t azure-mcp-server .
2. Push to AWS ECR
3. Create AWS Bedrock AgentCore runtime with this image
4. Runtime fails to start - AgentCore requires ARM64

Endpoint Issue:

1. Build for ARM64: docker build --platform=linux/arm64 -t azure-mcp-server .
2. Deploy to AWS Bedrock AgentCore as MCP runtime
3. Try to connect - AgentCore routes to /mcp but server exposes /
4. Connection fails because endpoint mismatch
5. Have to modify source code to change endpoint path

Environment

Deployment Target: AWS Bedrock AgentCore (requires ARM64)
Azure MCP Version: Latest from main branch
AgentCore Runtime Type: MCP
