Four tools with complete schemas and descriptions. Naming follows verb_noun pattern (search_, get_, list_, statistics_by_). Descriptions are substantive (100-200 chars), explaining what each tool does and when to use it. However, several parameter descriptions are minimal or missing. The 'limit' parameter in search_statistics lacks guidance on the default/max behavior. The 'slug' parameter in statistics_by_category has no description at all. Output schemas are not documented, LLMs cannot predict response structure. Error handling is basic (missing query returns text, no recovery guidance). No tool annotations (readOnlyHint, idempotentHint) despite all tools being read-only. Overall solid foundation but gaps in parameter clarity and output documentation prevent a higher score.

• Document output schema for each tool. Example: 'Returns array of statistic objects, each with {id, value, description, categoryTitle, source, permalink, embedUrl, citation}. See https://prestyj.com/data for field definitions.'
• Add description to 'slug' parameter: 'Category slug (e.g., speed-to-lead, ai-adoption-sales, industry-benchmarks). Call list_categories() to discover available slugs.'
• Add readOnlyHint: true to all four tools in ListToolsRequestSchema to signal they are safe, idempotent read operations.
• Enhance error handling in search_statistics: when no matches found, suggest 'Try list_categories() to browse available topics, or statistics_by_category() to explore a specific category.'
• Clarify limit parameter behavior: 'Max statistics to return (default 5, max 20). If limit > 20, capped at 20. If limit < 1, treated as 1.'
