MCP Server Database Connection Pooling

Connection pooling improves database performance for MCP servers handling multiple concurrent requests.

Pool Configuration

const pool = new Pool({
  host: process.env.DB_HOST,
  user: process.env.DB_USER,
  password: process.env.DB_PASSWORD,
  database: process.env.DB_NAME,
  max: 20, // Maximum pool size
  idleTimeoutMillis: 30000,
  connectionTimeoutMillis: 2000,
});
