This server implements two READ_ONLY web-oriented tools (search, web) with partial schema coverage. Both tools have reasonable descriptions (92-93 chars, within production baseline of 194 avg) and input schemas present. However, there are critical gaps: no output schema documentation, parameters lack descriptions for several fields, and no error handling guidance. The tools are appropriately named with action verbs (search_, web access pattern), but parameter documentation is incomplete, 'mode' in the web tool has a description but lacks an enum constraint, and 'max_length' has no description at all. No tool annotations (readOnlyHint, etc.) despite both being explicitly READ_ONLY. The schema quality is moderate (all params have types, but some lack descriptions), placing this in the 'Fair' to 'Poor' range for definition quality.

• Document the output schema for both tools. Specify what fields 'search' returns (e.g., results[], result.url, result.title, result.snippet, count, time_elapsed) and what 'web' returns (e.g., content, title, language, extracted_text, links[], confidence). Use a structured response format that downstream tools can consume.
• Add descriptions to all parameters. For 'web.max_length', add 'Maximum characters of content to return (0 = no limit); recommended 2000-4000 for token efficiency.' For 'search' optional params, add specifics: 'categories: comma-separated search categories (e.g., general,social media,news)' and similar for engines, language, time_range, format, safesearch.
• Formally constrain enumerable parameters with JSON Schema enum. Change 'web.mode' from free-form to { "enum": ["markdown", "raw", "links"] }. For 'search.format', add { "enum": ["json", "csv", "rss"] }. For 'search.safesearch', add { "enum": ["off", "moderate", "strict"] }.
• Add tool annotations to both tool definitions. Include { "readOnlyHint": true } to formally signal safety. This allows clients to categorize tools by risk and inform agent behavior.
• Document error responses and recovery paths. In tool descriptions or a separate error section, explain: 'If a search returns no results, try broader terms or different categories.' 'If URL fetch fails, verify the URL is valid and accessible.' Add timeouts and clear error messages from the underlying tools (SearXNG, aiohttp).
• Specify result limits in the 'search' tool description. Add: 'Returns up to 20 results per page (use pageno for pagination). Use time_range to filter recent results and improve relevance.'
