Implementation Reference

src/index.ts:1273-1283 (handler)

MCP tool handler that extracts arguments, calls generateStorageConfiguration from android-generators.ts, and returns the generated storage configuration as text content.

case 'dhis2_android_configure_storage':
  const storageArgs = args as any;
  const storageConfig = generateStorageConfiguration(storageArgs);
  return {
    content: [
      {
        type: 'text',
        text: storageConfig,
      },
    ],
  };

src/android-generators.ts:1186-1242 (helper)

Core helper function that generates comprehensive Android storage configuration code including database setup (Room/SQLite/Realm), encryption, caching strategies, purge policies, and usage examples based on input parameters.

export function generateStorageConfiguration(args: any): string {
  const { storageType, encryptionLevel, cacheStrategy, purgePolicy } = args;

  return `# DHIS2 Android Storage Configuration

## Database Technology: ${storageType.toUpperCase()}
## Encryption Level: ${encryptionLevel.toUpperCase()}

${generateDatabaseConfiguration(storageType, encryptionLevel)}

${cacheStrategy ? generateCacheStrategy(cacheStrategy) : ''}

${purgePolicy?.enabled ? generatePurgePolicy(purgePolicy) : ''}
