|---|---|
| echoA | 回显输入文本，可用于测试 server 是否连通。 Args: text: 要回显的文本。 Returns: 与输入完全一致的字符串。 |

Scored across 6 tools
Most tools have distinctly different purposes, but add and calculate both perform arithmetic, which could cause confusion. Descriptions help differentiate (add handles two numbers, calculate evaluates expressions), but the overlap is notable.
Tool names use lowercase with underscores for multi-word names, but the pattern is inconsistent: add, calculate, and echo are single verbs, while get_current_time and read_text_file follow verb_noun. This lack of uniformity reduces predictability.
With 6 tools, the server is well-scoped for a demo utility set. Each tool serves a clear role without being overwhelming or too sparse.
The tools cover common utility tasks like arithmetic, echoing, time retrieval, file reading, and system info. While it lacks some common utilities (e.g., string manipulation, random generation), it is adequate for a demo server with only minor gaps.
