Most tools have distinct purposes targeting specific resources (appointments, patients, invoices, test data) and actions, but there is some overlap between cleanup_test_data and cleanup_comprehensive_test_data, as well as generate_test_data and generate_comprehensive_test_data, which could cause confusion about which to use for test data management. The descriptions help clarify, but the boundaries are not perfectly clear.

Tool names follow a highly consistent verb_noun pattern throughout, such as create_appointment, get_patient, list_invoices, and update_appointment. All tools use snake_case with clear, descriptive verbs, making the naming predictable and easy to understand across the entire set.

With 27 tools, the count is on the high side for a typical MCP server, feeling somewhat heavy for the Cliniko domain. While it covers many aspects, it includes multiple test data and invoice-related tools that might be redundant or over-scoped, pushing it into the borderline range where efficiency could be impacted.

The tool set provides strong coverage for core Cliniko operations like CRUD on appointments and patients, listing resources, and handling invoices (though read-only). Minor gaps exist, such as no delete for invoice items or practitioners, and the invoice creation limitation is noted, but agents can work around these with the provided instructions and other tools.
