🏗️ Architecture

MCP Protocol Implementation

• Transport: StreamableHTTPServerTransport for HTTP-based communication
• Authentication: API key validation via HTTP headers
• Session Management: UUID-based session tracking with isolated state
• Registration: Dynamic tool/resource registration using SDK methods

Server Types

• Stateful Servers: Database operations with persistent connections
• Stateless Servers: Authentication and utility operations
• Template Server: Minimal example with all patterns

🛡️ Development Guidelines

For AI Assistants

CRITICAL: Read templates/mcp-server-template/prompts/ai-assistant-instructions.md

Key requirements:

• Use MCP SDK transports only (never custom HTTP)
• Use server.registerTool() for tool registration
• Validate with MCP SDK client
• Follow canonical template patterns

For Human Developers

1. Start with template: Copy templates/mcp-server-template/
2. Follow patterns: Use existing implementations as reference
3. Validate thoroughly: Use all test scripts
4. Deploy with Docker: Production-ready containerization included

📋 Validation Workflow

# 1. Template validation
node tests/validate-template.js

# 2. Server implementation
npm run build
npm start

# 3. MCP SDK client testing
node tests/test-auth-mcp-with-session.js

# 4. Architecture-aware testing
node tests/test-architecture-aware-mcp.js

🚀 Vision

Transform frontend applications into full-stack applications by automatically generating production-ready backends that handle:

• Form data processing and validation
• Database operations (PostgreSQL)
• File storage management (NAS CDN)
• RESTful API endpoints
• Deployment automation

🎯 Key Features

• Frontend Analysis: Parse React, Vue, Angular, and other frontend frameworks to understand data requirements
• Backend Generation: Create Golang services with proper architecture and best practices
• Database Integration: Automatic PostgreSQL schema generation and migrations
• File Storage: NAS CDN integration for media and document handling
• Git Integration: Automatic repository creation and management
• Continuous Updates: Keep backends in sync as frontends evolve

This project is in the early planning stages. Contributions to requirements gathering, architecture design, and implementation are welcome!

� Quick Start (Docker-Free)

For rapid local development without Docker hassles:

Option 1: Node.js MCP Servers (Recommended)

# Most MCP servers are Node.js/TypeScript - no containers needed
npm install -g @modelcontextprotocol/server-filesystem
npm install -g @modelcontextprotocol/server-github
# Run directly on your machine

Option 2: Python Virtual Environments

# Many servers available as Python packages
pip install mcp-server-postgres
pip install mcp-server-keycloak  # When we build it
# Native execution, no virtualization

Option 3: Windows Subsystem for Linux (WSL2)

# Lightweight Linux environment
wsl --install
# Better than Docker Desktop for development

Cross-Service Communication

• HTTP APIs: Direct service-to-service calls
• Shared File System: Use Windows file sharing for data exchange
• Local Database: PostgreSQL/Redis running as Windows services
• Message Queues: Use local Redis for async communication

🔐 Auth MCP Server Validation

This repository includes an Auth MCP Server template that provides Keycloak and Infisical integration. To validate the deployed server:

Prerequisites

1. Create a .env file with your configuration:

cp .env.example .env
# Edit .env with your actual values:
# AUTH_MCP_URL="https://your-auth-server.com/mcp"
# AUTH_MCP_API_KEY="your-api-key"

Validation Options

Option 1: Quick Node.js Validation

node validate-auth-mcp-simple.js

Option 2: Bash Script Validation

chmod +x validate-auth-mcp.sh
./validate-auth-mcp.sh

Option 3: Manual cURL Tests

# Load environment variables
source .env

# Test health endpoint (no auth)
curl "${AUTH_MCP_URL%/mcp*}/health"

# Test unauthenticated request (should return 401)
curl -X POST -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","method":"initialize","id":1}' \
  "$AUTH_MCP_URL"

# Test authenticated request (should work)
curl -X POST -H "Content-Type: application/json" \
  -H "API_KEY: $AUTH_MCP_API_KEY" \
  -d '{"jsonrpc":"2.0","method":"initialize","id":1,"params":{"protocolVersion":"1.0","capabilities":{}}}' \
  "$AUTH_MCP_URL"

MCP Inspector Configuration

For development with MCP Inspector, use the environment-based config:

# Copy the environment-based MCP config
cp .vscode/mcp-env.json .vscode/mcp.json
# Ensure AUTH_MCP_API_KEY is in your environment

🤖 AI/Copilot Guardrails

This project includes comprehensive AI assistant guardrails through VS Code Copilot custom modes and instructions:

🎯 Specialized Chat Modes

• MCP Server Development: Comprehensive development mode with template enforcement and validation workflows
• MCP Server Validation: Testing and compliance checking with systematic validation procedures
• MCP Troubleshooting: Systematic debugging with guided troubleshooting and proven solutions

🛡️ AI Development Guardrails

Critical Context: The Model Context Protocol (MCP) is NOT in AI training data. The guardrails ensure:

1. Template Compliance: Always reference templates/mcp-server-template/ for canonical patterns
2. Protocol Adherence: Mandatory use of MCP SDK transports and proper tool registration
3. Validation Requirements: All servers must pass MCP SDK client testing
4. Security Standards: Integration with Keycloak and Infisical, proper input validation
5. Submodule Architecture: Each server in mcp-servers/ is independent with own tests and docs

These guardrails prevent common MCP development mistakes and ensure all AI-assisted development follows proven patterns from the working reference implementations.
