Most tools have distinct purposes targeting specific resources and actions, but there is some ambiguity between get_subscription and get_subscription_details. The descriptions clarify that get_subscription returns limited data requiring follow-up calls, while get_subscription_details provides complete info, but an agent might still be confused about which to use in different scenarios.

All tools follow a consistent verb_noun naming pattern (e.g., create_customer, get_payment, list_subscriptions). The verbs are standardized (create, get, list) and nouns are clear, with no mixing of conventions like camelCase or snake_case deviations.

With 12 tools, the count is well-scoped for a payment processing domain like GoCardless. It covers core resources (customers, payments, mandates, subscriptions, payouts) with appropriate CRUD operations, avoiding bloat while providing essential functionality.

The tool set offers strong coverage for key resources with create, get, and list operations, but lacks update and delete tools for most entities (e.g., no update_customer or delete_payment). This minor gap might require workarounds, but core workflows like creating and retrieving data are well-supported.
