The server implements two tools:

create_account_holder: Create an account holder using the Ntropy API
- Takes "id", "type", "name" as required string arguments
- Returns the created account holder
enrich_transaction: Enrich a transaction using the Ntropy API
- Takes "id", "description", "date", "amount", "entry_type", "currency", "account_holder_id" as required string arguments, and "country" as an optional argument
- Returns the enriched transaction
