The server defines 4 tools with basic verb-noun naming conventions (get_*, search_*, check_*) and includes descriptions in German. However, critical gaps exist: (1) Parameter descriptions are minimal or absent in JSON schemas, the schema shows parameter names but lacks the descriptions that LLMs rely on to understand what values to pass. (2) Output schemas are not documented, return types are inferred from code (list, str) but not formally declared for agent consumption. (3) No error handling guidance, tools return empty lists or empty strings on failure without telling the LLM what went wrong or how to recover. (4) No pagination support despite tools that could return large results (search_web, get_wikipedia_article). Per-tool analysis: get_current_time_and_date (straightforward, no params, acceptable); search_web (has num_results default=5, good); get_wikipedia_article (basic); check_available_wikipedia_articles (returns list but no pagination). Descriptions are written in German, which is not ideal for LLM understanding in multilingual contexts, most production tools use English. Code shows no input validation, no retry guidance, and fragile web scraping (BeautifulSoup selectors could break).

• Add description fields to all parameter definitions in FastMCP schema. For search_web: 'search_term (str): The search query to execute. Required.' and 'num_results (int): Maximum number of results to return. Range: 1 - 20. Default: 5.'
• Document return types and field schemas. For search_web, add 'Returns: List[Dict] with keys: title (str), link (str), snippet (str). Example: [{"title": "Example", "link": "https://...", "snippet": "..."}]'.
• Translate descriptions to English or provide both English and German variants. Prioritize English for LLM compatibility.
• Add explicit error handling that returns structured error objects rather than empty lists. E.g., {'error': 'Service unavailable', 'status': 'retryable', 'guidance': 'Try again in 30 seconds'} instead of [].
• Implement pagination for search_web and get_wikipedia_article. Add optional offset/limit parameters and return a total_results or next_cursor field.
• Add input validation and bounds checking. E.g., num_results must be 1 - 20; return a validation error if out of range.
• Consider using a robust HTTP client library with retry logic (e.g., requests.adapters.Retry) instead of relying on raw requests.get().
• Add tool annotations (readOnlyHint=true for all tools since they do not modify state) to signal to agents that these tools are safe to call freely.
