This tutorial server demonstrates basic MCP patterns but falls short of production quality. Tool names lack consistent verb prefixes (hello, add, get_weather are inconsistent; baidu_web_search is better). Descriptions exist but are often verbose and include implementation details (e.g., 'file_path=文件的完整路径(如 D:/projects/data.txt 或 C:/Users/name/note.md)') rather than LLM-optimized guidance. Parameter descriptions are present but inconsistent in quality. No output schemas are documented. Error handling returns plain strings without recovery guidance. The file-reader tool includes good security (extension whitelist, size limits) but lacks structured error categorization. Overall, this reads as educational material rather than production-grade tooling.

• Move parameter documentation from tool descriptions into structured parameter descriptions. E.g., for read_text_file, move 'file_path=文件的完整路径(如 D:/projects/data.txt 或 C:/Users/name/note.md)' into the file_path parameter's description field.
• Document output schemas for all tools. E.g., baidu_web_search should declare it returns a string with format 'title [date]\n url\n snippet', or better yet, return structured JSON with title, url, date, snippet fields.
• Add error-classification guidance to error responses. E.g., 'API Key invalid (user-fixable: set BAIDU_API_KEY environment variable)' instead of just 'API Key 无效或未设置'.
• Rename 'hello' to 'greet_user' and 'add' to 'add_numbers' to establish consistent verb_noun naming across all tools.
• Replace inline example values in baidu_web_search description with enum constraints in the schema. Define recency as enum: ['week', 'month', 'semiyear', 'year'] instead of listing in description text.
