echo and get_system_info are clearly distinct operations, and my_custom_tool is not described in a way that directly overlaps with them. However, the placeholder description for my_custom_tool leaves its actual purpose ambiguous, so the set is not perfectly unambiguous.

The naming is inconsistent: echo uses a bare verb, get_system_info follows verb_noun, and my_custom_tool uses a vague custom label. There is no shared naming convention across the three tools.

Three tools is not an unreasonable number by itself, but the set feels like a minimal scaffold rather than a focused server. The unrelated utilities and placeholder custom tool make the count less defensible than it would be with a clear shared purpose.

The server lacks a coherent domain, so it is difficult to determine what complete coverage would look like. echo and get_system_info are isolated utilities, while my_custom_tool is an unspecified placeholder, leaving obvious gaps in any implied workflow.
