This server provides 7 well-structured research tools with consistent patterns. All tools are READ_ONLY and have proper Zod schemas with type definitions. Naming is clear and action-verb driven (search_*, get_*). Descriptions are present and adequate (ranging from 34-70 chars). However, there are notable gaps: (1) Output schemas are NOT documented, the code returns JSON.stringify() with no schema definition for what fields consumers should expect, (2) Parameter descriptions lack granularity, many params like 'filter' and 'sort' mention OpenAlex API syntax (e.g., 'publication_year:2023') but don't explain when to use them or their constraints, (3) Error handling is minimal, errors are caught but messages are generic ('Error: ' + string), with no guidance for recovery or retry logic, (4) No indication of maximum result limits despite mentioning 'max: 200' for per_page, no statement of what the default limit returns, (5) No pagination guidance beyond per_page parameter, unclear if more results exist or how to fetch next page. The 'verbose' boolean flag is interesting but under-documented (concise mode returns 'select' fields, but users don't see what those fields are). Overall, the tools are solid for basic research but lack the depth needed for production LLM integration.

• Document output schema for each tool. Example: search_works returns { results: [ { id, doi, display_name, publication_year, cited_by_count, ... } ], total: number, per_page: number }. Include this in the tool description or as a separate schema block.
• Enhance error handling to categorize errors: retryable (rate limit, timeout), user-fixable (no results found, invalid filter syntax), or fatal (auth failure). Example: 'No results found. Try a broader search query or different filters.'
• Clarify filter and sort parameter formats with examples in the description. Better: 'Filter string using OpenAlex syntax (e.g., publication_year:2023 to restrict to 2023, is_oa:true to show open-access only). Multiple filters joined by comma.'
• Document pagination strategy: 'Use per_page to control results per request (1-200, default 10). This tool returns all matching results up to per_page in a single call; use page offset in the API if more results exist (not yet implemented in this tool).'
• Document the verbose flag: 'If true, returns full object details. If false (default), returns concise summary: id, display_name, publication_year, cited_by_count. Concise mode is faster and cheaper for LLM reasoning.'
• Add a result-limit statement to search tools: 'Returns up to 200 results per request. For large result sets, use filters to narrow scope.' This prevents LLMs from assuming all matching works are returned.
• Include IDs needed for chaining. Ensure search results include both 'id' (OpenAlex ID) and 'doi' (for get_work_by_id), and that get_* tools accept both formats.
