🚀 Quick Deployment

1. Install Vercel CLI

npm install -g vercel

2. Set Environment Variables

Create a .env file (copy from .env.example):

DATABASE_URL_PRIVATE="postgresql://user:pass@host/private?sslmode=require"
DATABASE_URL_PUBLIC="postgresql://user:pass@host/public?sslmode=require"

3. Deploy to Vercel

cd vercel-deployment
vercel

Follow the prompts:

• Set up and deploy? Y
• Which scope? Select your account
• Link to existing project? N (for first deployment)
• What's your project's name? finance-mcp-server
• In which directory is your code located? ./
• Want to override settings? N

4. Add Environment Variables to Vercel

After deployment, add your secrets:

# Add private database URL
vercel env add DATABASE_URL_PRIVATE

# Add public database URL
vercel env add DATABASE_URL_PUBLIC

Or add them via Vercel Dashboard:

1. Go to your project settings
2. Navigate to "Environment Variables"
3. Add DATABASE_URL_PRIVATE and DATABASE_URL_PUBLIC
4. Redeploy: vercel --prod

🔧 Configuration

vercel.json

The vercel.json file configures:

• Python runtime for serverless functions
• Routing to handle MCP endpoints
• Environment variables references

Production Deployment

vercel --prod

Your MCP server will be available at:

https://your-project.vercel.app/mcp

📡 API Endpoints

Once deployed, your MCP server will be accessible at:

• Main MCP endpoint: https://your-project.vercel.app/mcp
• Health check: https://your-project.vercel.app/

🔐 Security

1. Never commit .env file - it's already in .gitignore
2. Use Vercel environment variables for production secrets
3. Enable SSL - Vercel provides automatic HTTPS
4. Database SSL - Ensure Neon databases use ?sslmode=require

Local Testing

# Install dependencies
