**Production Stack:**
- **Runtime**: Docker Compose orchestration on AWS EC2
- **Proxy**: Nginx with custom logging format and upstream health checks
- **Security**: IP-whitelisted KuCoin API keys, Notion integration tokens
- **Observability**: Structured audit logging, request tracing, health endpoints
- **CI/CD**: GitHub Actions with GHCR registry and zero-downtime deployments

- **Secrets management** via environment variables (SSM-ready)
- **Audit trail** for all tool invocations with request/response logging
- **Least-privilege access** patterns throughout the stack
### ⚡ **Scalability & Reliability**
- **Container orchestration** with health checks and restart policies
- **Reverse proxy** with upstream connection pooling
- **Graceful degradation** with circuit breaker patterns
- **Zero-downtime deployments** via blue-green strategy
- **Resource optimization** with multi-stage Docker builds
---
## 🚀 Quick Start
### Prerequisites
```bash
# Required tooling
✅ Python 3.12+ with uv package manager
✅ Docker & Docker Compose v2+
✅ AWS EC2 with Elastic IP
✅ GitHub Container Registry access
```
### Local Development
```bash
# 1️⃣ Environment setup
git clone https://github.com/yourusername/mcp-crypto-portfolio.git
cd mcp-crypto-portfolio
# 2️⃣ Configuration
cp .env.example .env
# Configure your secrets (see Configuration section)
# 3️⃣ Install dependencies
uv venv --python 3.12
uv pip install -e ".[dev]"
# 4️⃣ Run locally
uv run python -m src.server
# ✅ Verify deployment
curl -i http://127.0.0.1:3333/mcp
# Expected: HTTP/1.1 406 Not Acceptable (MCP requires specific headers)
```
---
## ⚙️ Configuration
### Environment Variables
```bash
# KuCoin API Configuration (Read-Only)
KUCOIN_API_KEY=pk_live_xxxxxxxxxxxxxxxxx
KUCOIN_API_SECRET=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
KUCOIN_API_PASSPHRASE=your-secure-passphrase
KUCOIN_BASE_URL=https://api.kucoin.com
KUCOIN_KEY_VERSION=2 # Optional: force specific API version
# Notion Integration
NOTION_TOKEN=secret_ntn_xxxxxxxxxxxxxxxxxxxxxxx
NOTION_DATABASE_ID=xxxxxxxxxxxxxxxxxxxxxxxxxxxx
# Server Configuration
MCP_HOST=0.0.0.0
MCP_PORT=3333
PYTHONPATH=/app
# Production Overrides
LOG_LEVEL=INFO
AUDIT_ENABLED=true
HEALTH_CHECK_TIMEOUT=30
```
### KuCoin API Setup (Production-Grade)
1. **Create API Key**: KuCoin → API Management → New Key
2. **Permissions**: Select **"General"** (read-only) permissions only
3. **IP Whitelisting**: Add your **EC2 Elastic IP** at key creation
4. **Security Note**: Editing IP whitelist post-creation can be unreliable - create new keys when needed
5. **Validation**: Test with minimal read operations before production deployment
### Notion Workspace Integration
1. **Create Integration**: [Notion Developers](https://developers.notion.com) → New Integration
2. **Permissions**: Read/Write access to databases and pages
3. **Share Resources**: Add integration to your target database/pages
4. **Database Schema**: Ensure compatible column types for portfolio data

## 🔌 Claude Integration
### Desktop Configuration
Edit `~/Library/Application Support/Claude/claude_desktop_config.json`:
```json
{
"mcpServers": {
"mcp-crypto-portfolio": {
"command": "npx",
"args": [
"mcp-remote",
"http://YOUR_ELASTIC_IP/mcp",
"--allow-http"
],
"env": {
"NODE_TLS_REJECT_UNAUTHORIZED": "0"
}
}
}
}
```
### API Integration (Enterprise)
```python
import openai
from mcp import ClientSession, StdioServerParameters
from mcp.client.stdio import stdio_client
# Configure MCP client
async def setup_mcp_client():
server_params = StdioServerParameters(
command="npx",
args=["mcp-remote", "http://your-server/mcp", "--allow-http"]
)
async with stdio_client(server_params) as (read, write):
async with ClientSession(read, write) as session:
# Initialize connection
await session.initialize()
# List available tools
tools = await session.list_tools()
print(f"Available tools: {[tool.name for tool in tools.tools]}")
# Call portfolio analysis
result = await session.call_tool("portfolio_report", {
"include_risk_analysis": True,
"generate_notion_report": True
})
return result
```
### Sample Interactions
```markdown
**User**: "Check my crypto portfolio and create a risk analysis report"
**Claude**: I'll check your KuCoin portfolio and generate a comprehensive risk analysis report in Notion.
*[Calls get_balances tool]*
*[Calls portfolio_report tool with risk analysis enabled]*
*[Calls upsert_holdings tool to update database]*
Your portfolio analysis is complete! Here's what I found:
📊 **Portfolio Overview:**
- Total Value: $12,450.32
- Assets: 8 cryptocurrencies
- Top Holdings: BTC (45%), ETH (30%), SOL (12%)
⚠️ **Risk Analysis:**
- High concentration risk in BTC
- 3 dust positions detected (<$10 each)
- Recommended rebalancing threshold: 40%
📝 **Notion Report:** Created detailed report page with charts and recommendations.
```
---
## 📊 Monitoring & Observability
### Health Monitoring
```bash
# Application health
curl -f http://your-server/health
# Container status
docker-compose ps
# Resource usage
docker stats --no-stream
# Log analysis
docker-compose logs --tail=100 app | jq 'select(.level=="ERROR")'
```
### Audit Logging
Every tool invocation is logged with structured data:
```json
{
"timestamp": "2024-01-15T10:30:45.123Z",
"event": "tool_call",
"tool_name": "get_balances",
"session_id": "mcp_session_abc123",
"request_id": "req_def456",
"parameters": {},
"execution_time_ms": 1250,
"status": "success"
}
```
### Performance Metrics
- **Response Times**: P50 < 500ms, P95 < 2s, P99 < 5s
- **Availability**: 99.9% uptime target
- **Error Rates**: < 0.1% tool call failures
- **Resource Usage**: < 80% CPU, < 1GB RAM

## 🔧 Troubleshooting Guide
### Common Issues
#### 🚨 502 Bad Gateway on /mcp
```bash
# Check application status
docker-compose ps
# View application logs
docker logs mcp-crypto-portfolio --tail=50
# Test internal connectivity
docker exec mcp-nginx curl -i http://app:3333/mcp
# Verify network configuration
docker network inspect mcp-crypto-portfolio_app_network
```
#### 🚨 KuCoin API Authentication Failures
```bash
# Verify egress IP matches whitelist
docker exec mcp-crypto-portfolio python -c "
import urllib.request
print('Egress IP:', urllib.request.urlopen('https://api.ipify.org').read().decode())
"
# Test API credentials
docker exec mcp-crypto-portfolio python -c "
import os
from src.kucoin_client import KucoinClient
client = KucoinClient()
print('API Test:', client.get_accounts())
"
# Check time synchronization (critical for signatures)
chronyc tracking
```
#### 🚨 Container Restart Loops
```bash
# Check resource constraints
docker stats --no-stream
# Examine startup logs
docker logs mcp-crypto-portfolio --since=10m
# Validate image integrity
docker run --rm ghcr.io/yourusername/mcp-crypto-portfolio:latest python -c "import src.server; print('OK')"
```
#### 🚨 Notion Integration Issues
```bash
# Verify token and permissions
docker exec mcp-crypto-portfolio python -c "
import os
from src.notion_client import NotionClient
client = NotionClient()
print('Notion Test:', client.test_connection())
"
# Check database schema compatibility
curl -H "Authorization: Bearer $NOTION_TOKEN" \
-H "Notion-Version: 2022-06-28" \
"https://api.notion.com/v1/databases/$NOTION_DATABASE_ID"
```
### Performance Optimization
#### Memory Usage
```bash
# Monitor memory patterns
docker exec mcp-crypto-portfolio python -c "
import psutil, gc
print(f'Memory: {psutil.virtual_memory().percent}%')
print(f'Objects: {len(gc.get_objects())}')
"
# Configure Python memory limits
export PYTHONMALLOC=malloc
export MALLOC_ARENA_MAX=2
```
#### API Rate Limiting
```nginx
# Enhanced rate limiting in nginx.conf
limit_req_zone $binary_remote_addr zone=strict:10m rate=1r/s;
location /mcp {
limit_req zone=strict burst=5 nodelay;
# ... rest of configuration
}
```
---
## 🔒 Security Hardening
### API Security
- **Read-Only Access**: KuCoin keys restricted to balance queries only
- **IP Whitelisting**: API access limited to known server IPs
- **Credential Rotation**: Quarterly key rotation recommended
- **Request Signing**: All KuCoin requests use HMAC-SHA256 signatures
- **Rate Limiting**: Built-in protection against API abuse
### Infrastructure Security
- **TLS Encryption**: HTTPS termination at Nginx (production)
- **Security Headers**: HSTS, CSP, X-Frame-Options configured
- **Container Isolation**: Non-root user, minimal base images
- **Network Segmentation**: Private Docker networks
- **Secret Management**: Environment-based configuration
### Recommended Enhancements
```bash
# 1. Enable TLS with Let's Encrypt
sudo certbot --nginx -d your-domain.com
# 2. Configure AWS Systems Manager for secrets
aws ssm put-parameter --name "/mcp-portfolio/kucoin-key" --value "pk_live_xxx" --type SecureString
# 3. Enable CloudWatch logging
docker run --log-driver=awslogs --log-opt awslogs-group=mcp-portfolio
# 4. Set up AWS WAF
aws wafv2 create-web-acl --scope CLOUDFRONT --default-action Allow={}
```
