Implement Docker-based MCP Server

[Copilot]

This PR implements a containerized Model Context Protocol (MCP) server using Node.js and Docker in the docker-mcp folder. The implementation provides a complete, production-ready MCP server that follows the protocol specification.

Features

• Complete Node.js implementation of the Model Context Protocol server
• Session management with in-memory storage
• Support for both transport options:
  • Modern Streamable HTTP endpoint (/v1/text/completions)
  • Legacy HTTP+SSE endpoint (/v1/text/completions/stream)
• OAuth discovery endpoint and placeholder authentication
• Error handling and logging using Winston
• Comprehensive test suite using Jest
• Docker containerization with proper production settings

Implementation Details

• Used Express.js for the web server framework
• Implemented a modular architecture with controllers, models, and services
• Created class-based models that match the MCP specification
• Added a simple session service for managing user sessions
• Included structured error handling and logging

Deployment

The server can be deployed using either Docker directly or Docker Compose:

# Using Docker
docker build -t mcp-server .
docker run -p 3000:3000 mcp-server

# Using Docker Compose
docker-compose up

The implementation includes a comprehensive README with detailed instructions for building, running, and using the server.

Fixes #14.
