This server demonstrates significant quality gaps across naming, descriptions, schemas, and error handling. The two tools are minimally documented, lack comprehensive input schemas, and provide no guidance for error recovery. While the tools follow a basic verb_noun pattern, descriptions are superficial (under 100 chars), parameter types are incomplete, and output schemas are not documented. The server uses the mcp-use framework which abstracts some MCP mechanics, but source code visibility is severely limited, tool definitions cannot be directly verified from the provided code snippets. The framework appears to delegate actual tool registration to imported functions (e.g., registerProductSearch), but the actual schema definitions are not shown, forcing inference. Per the hard scoring rules, inferred tool definitions cap individual tools at 50; combined with missing/incomplete documentation across both tools, the overall score reflects poor definition quality.

• Provide complete tool implementation files in source review (tools/product-search.ts, tools/get-fruit-details.ts) so tool definitions can be verified, not inferred.
• Add comprehensive input schemas: search-tools.query should include {type: 'string', minLength: 1, maxLength: 100, description: 'Search query using partial or exact fruit names (case-insensitive). Examples: "apple", "ber" matches blueberry.'} and get-fruit-details.fruit should include an enum of valid fruit names or a pattern constraint.
• Expand tool descriptions to 100-200 chars explaining WHAT each tool does, WHEN to use it, and what it returns. Example for search-tools: 'Search the fruit catalog by name or partial match. Use this to discover available fruits or narrow results. Returns up to 20 matching fruits with color info. Use get-fruit-details() to fetch full nutritional data for a specific fruit.'
• Document output schemas explicitly. E.g., search-tools output: {results: [{fruit: string, color: string}], total: number, next_page: string?}. get-fruit-details output: {fruit: string, color: string, nutrition: {calories: number, ...}, price: number}.
• Add error handling guidance. Specify common failure modes and recovery steps: 'If no results, try search-tools() with a shorter query. If fruit not found, get-fruit-details() returns 404, use search-tools() to verify fruit exists.'
• Standardize parameter naming and casing: Use search_query instead of query (more specific). Ensure all params have {type, description, required, and constraints (minLength, enum, pattern, default)}.
