Tool Definition Quality
A4.4/5.0
Tool DescriptionsA
Average 4.6/5 across 19 of 19 tools scored. Lowest: 4/5.
Server CoherenceA
Disambiguation3/5
There is some overlap among get_account_balance, get_accounts_detail, and list_accounts, which all return account data including balances. get_credit_card_bill vs list_credit_card_bills are distinct, but the account-level tools may cause confusion about which to use for a given task.
Naming Consistency5/5
All tools follow the openfinance_ prefix with a clear verb-noun pattern (get, list, update, search, disconnect, force_sync). The only minor exception is provider_status which lacks a verb, but it remains consistent and understandable.
Tool Count5/5
19 tools is well-scoped for an Open Finance banking API, covering connections, accounts, transactions, bills, investments, loans, categories, and operational checks without being excessive or sparse.
Completeness5/5
The toolset covers the core banking operations comprehensively: listing and getting accounts, transactions, bills, investments, loans, managing connections (sync, disconnect, search), updating categories, and checking provider/connection status. No obvious gaps for the stated domain.
