Most tools target distinct actions: volume control, mute control, power control, status, and input selection. The only minor overlap is mute_on/mute_off/mute_toggle, where toggle is redundant with the explicit setter tools, but descriptions are clear enough to avoid serious confusion.

Tool names mostly follow a predictable snake_case pattern with noun prefixes like volume_, mute_, power_. Minor inconsistency exists with get_status and set_input, which place the verb first, but this is still readable and clearly structured.

Ten tools is well-scoped for a Denon AVR control server. Every tool covers a meaningful function: volume, mute, power, status, and input, without unnecessary bloat or trivial duplicates.

The core AV receiver control surface is covered: volume adjust and set, mute control, power on/off, status retrieval, and input selection. Minor gaps exist such as missing per-zone controls or more advanced audio settings, but the essential operations are complete.
