Each tool targets a distinct resource and action within Nacos config or service discovery. There is no overlap between similar-sounding tools like get_service (metadata for one service) and list_services (all services), or between get_config (current content) and get_config_history (past versions). The boundaries are clear from the names and descriptions.

All tools follow a strict nacos_<verb>_<noun> pattern in snake_case. Verbs like get, list, create, delete, publish, register, deregister, and update are used consistently, and plural nouns are used for list operations while singular nouns are used for single-resource operations.

16 tools across two major Nacos subdomains (config management and service discovery) is slightly above the typical 3–15 range but each tool earns its place. No redundant or filler tools are present, though the set could be marginally trimmed if some rarely used operations were merged.

Config lifecycle (get, publish/update, delete, list, history, rollback) and instance lifecycle (register, deregister, update, list) are well covered. Minor gaps exist, such as no explicit update_namespace tool and no way to delete a service directly, but these are workaroundable in typical Nacos usage.
