# Unified Configuration System
Unified configuration system for both old and new servers.
## Components
### ArgumentsParser
Parses command-line arguments and environment variables.
```typescript
import { ArgumentsParser } from './config';
const args = ArgumentsParser.parse();
// args.mcp, args.env, args.transport, etc.
```
### ConfigLoader
Loads YAML configuration and merges with CLI arguments (CLI takes priority).
```typescript
import { ConfigLoader } from './config';
const config = ConfigLoader.load();
// config.defaultMcpDestination, config.transport, etc.
```
### ServerConfig
Unified server configuration interface.
```typescript
import { ServerConfig } from './config';
const config: ServerConfig = {
defaultMcpDestination: 'trial',
transport: { type: 'stdio' },
unsafe: false,
useAuthBroker: true,
// ...
};
```
## Usage with AuthBrokerFactory
```typescript
import { ConfigLoader } from './config';
import { AuthBrokerFactory } from '../authBrokerFactory';
// Load configuration
const serverConfig = ConfigLoader.load();
// Create AuthBrokerFactory from configuration
const authBrokerFactory = AuthBrokerFactory.fromServerConfig(serverConfig);
// Get AuthBroker for destination
const authBroker = await authBrokerFactory.getOrCreateAuthBroker('trial');
```
## Integration in Old Server
```typescript
// In mcp_abap_adt_server
import { ConfigLoader } from './lib/config';
import { AuthBrokerFactory } from './lib/authBrokerFactory';
async run() {
// Load configuration
const serverConfig = ConfigLoader.load();
// Create AuthBrokerFactory
const authBrokerFactory = AuthBrokerFactory.fromServerConfig(serverConfig);
// Use as before
const authBroker = await authBrokerFactory.getOrCreateAuthBroker(serverConfig.defaultMcpDestination);
}
```
## Integration in New Server (StdioServer, SseServer, StreamableHttpServer)
```typescript
// In BaseMcpServer or specific servers
import { ConfigLoader } from './lib/config';
import { AuthBrokerFactory } from './lib/authBrokerFactory';
class StdioServer extends BaseMcpServer {
async start() {
// Load configuration
const serverConfig = ConfigLoader.load();
// Create AuthBrokerFactory
const authBrokerFactory = AuthBrokerFactory.fromServerConfig(serverConfig);
// Get AuthBroker
const authBroker = await authBrokerFactory.getOrCreateAuthBroker(serverConfig.defaultMcpDestination);
// Set connection context
await this.setConnectionContext(serverConfig.defaultMcpDestination!, authBroker);
// Register handlers
this.registerHandlers(handlersRegistry);
// Start transport
const transport = new StdioServerTransport();
await this.server.connect(transport);
}
}
```
## Benefits
1. **Unified Logic** - Single configuration system for both old and new servers
2. **CLI Priority** - Command-line arguments override YAML values
3. **YAML Support** - Use configuration file instead of long command-line arguments
4. **Type Safety** - TypeScript interfaces for all configurations
5. **Backward Compatibility** - Old code continues to work
