This server has exactly 1 tool (get_presentations) with critical quality gaps. The tool has a valid name and basic description, but the input schema is severely malformed and non-functional. The schema declares a generic 'operation' parameter of type string with no description, no enum constraints, and no explanation of what values are valid. The tool description is only 57 characters and provides no guidance on when to use it, what it returns, or what the operation parameter does. There are no parameter descriptions whatsoever. The output is unstructured text (Presentation.toString()) rather than structured JSON with typed fields. No error handling, no pagination support, and no security considerations are evident.

• Clarify or remove the 'operation' parameter. If it filters results (by year, category, speaker), define it as an enum with explicit values in the schema and describe each in the parameter annotation. Example: operation: 'all' | 'recent' | 'featured'. If unused, remove it entirely.
• Expand the tool description to 100-150 characters explaining: (1) What it retrieves ('Get all JavaOne presentations with title, URL, and year'), (2) When to call it ('Use to find talks to watch or share'), (3) What to do next ('Results are sorted by year; use title field to identify specific talks').
• Add a description to the operation parameter (if kept): 'Optional filter to narrow results. Valid values: all (default, all presentations), recent (2025 only), featured (keynotes only). If omitted, returns all presentations.'
• Change output from unstructured text to structured JSON. Return an array of objects: [{title: string, url: string, year: number}, ...]. Document this in the tool description.
• Add pagination: Accept optional limit (1-100, default 20) and offset (default 0) parameters. Return {presentations: [...], total_count: number, has_more: boolean}.
• Add error handling: If operation has an invalid value, return a clear error like 'Invalid operation: got "xyz", valid values are: all, recent, featured'.
• Consider splitting into multiple focused tools: get_all_presentations (returns all), search_presentations_by_year (takes year as required parameter), get_featured_presentations (no parameters). This follows the single-responsibility pattern and makes the LLM's choice explicit.
