The ReferenceSearch server has one clearly-defined tool with a verbose, well-structured description and complete parameter schema. The tool naming follows the pattern (search_reference, verb-first) and addresses a focused domain (academic reference search). Parameters are well-typed with descriptions and constraints (min/max for max_results). However, the output schema is not explicitly documented in the visible source code, and error handling guidance is absent. The description is comprehensive but somewhat long (1100+ chars, above the 1024 baseline recommendation), which could impact token efficiency. The server uses FastMCP with HTTP transport and includes caching logic, suggesting production-readiness patterns. No security concerns detected for a read-only tool, though no explicit error classification or recovery guidance is present.

• Add explicit return type schema documentation to the tool registration showing the structure of BibTeX citations and metadata fields returned (e.g., { type: 'object', properties: { bibtex: {type: string}, title: {type: string}, authors: {type: array}, year: {type: integer}, abstract: {type: string}, doi: {type: string}, ... } }).
• Reduce tool description from ~1100 to 200-300 characters by moving rationale to server-level instructions (already partially done). Keep only: 'Search academic databases (DBLP, Semantic Scholar, arXiv, OpenAlex) for research papers and return BibTeX citations with metadata. Use this when you need citations, paper details, or literature search results.'
• Add to the 'query' parameter description: 'Required. Search terms (titles, author names, years, DOIs, arXiv IDs). Minimum 3 characters. Special characters (quote marks, operators like AND/OR) are not supported, use plain text.'
• Document expected errors with recovery guidance: 'If no results found for a query, try broadening the search term (remove year filter, use partial author names, or search by topic keywords). If external databases are unreachable (network timeout), the tool will return a cached result from the last 10 minutes if available; otherwise, it will fail with a timeout error.'
• Add pagination clarity: 'Results are ranked by relevance and truncated to max_results. If you need additional papers, retry with a modified query (e.g., different author, year range) or increase max_results up to 100. The tool does not support offset-based pagination.'
