This server implements 2 tools with generally good structure and clarity. Tool names follow verb-noun convention (search_*, fetch_*). Descriptions are present and moderately detailed (ranges 90-130 chars). Input schemas are well-defined using Zod with proper type constraints and descriptions. Output is returned as JSON text. However, output schemas are not documented, error handling lacks recovery guidance, and tool annotations (readOnlyHint) are missing. The server demonstrates solid baseline quality but lacks some polish expected of production-grade tools.

• Add explicit output schemas to tool definitions. Example for search_anthropic_docs: document that output is JSON array [{title: string, url: string, snippet: string}, ...] with max 10 items.
• Document the DocumentResult output structure for fetch_doc: {url: string, title: string, text: string, truncated?: boolean}.
• Add readOnlyHint annotation to both tools: register with {readOnlyHint: true} in the inputSchema or tool metadata.
• Enhance error messages with recovery steps. Example: on fetch 404, respond 'Failed to fetch {url}. Try searching for this topic with search_anthropic_docs to find alternative documentation.'
• Clarify the relationship between tools in descriptions. Example for search: 'Use to discover documentation URLs. Once you have a URL, call fetch_doc to retrieve full content.'
• Document query syntax for search_anthropic_docs. Example: 'Query string, case-insensitive. May include words like: mcp, api, authentication, models, examples.'
• Add guidance on max_results parameter: 'Higher values return more results but may be slower. Default 5 is recommended; use 10 only if first 5 are insufficient.'
