This server has 4 tools with explicit registrations visible in src/server.ts. All tools have basic descriptions and input schemas with proper JSON Schema structure. However, there are significant gaps in parameter descriptions, output schema documentation, and error handling guidance that prevent higher scores. The tool names follow verb_noun conventions (fetch_, search_, extract_, summarize_) which is good. Most parameters lack detailed descriptions explaining constraints, formats, and dependencies. Output schemas are not documented, responses mention returning 'content' arrays with 'text' and 'image' types, but the structure is not formally specified. Error handling exists but returns generic error messages without recovery guidance. This is a typical community MCP server with functional definitions but production gaps.

• Document the output schema for each tool explicitly. For fetch_page, specify: 'Returns { content: [{ type: "text", text: string }, ...], isError?: boolean }'. Include field types and meanings.
• Add min/max bounds and units to numeric parameters. E.g. 'maxContentLength (number, 1 - 100000, default 10000): Maximum characters to return. Larger values increase latency.' Similarly for maxLength, maxResults.
• Enhance error messages with recovery guidance. Instead of 'Error fetching page: <msg>', return 'Failed to fetch <url>: <specific reason>. Verify the URL is accessible and try again, or use search_documentation() to find an alternative source.'
• Clarify the distinction between fetch_page, search_documentation, and extract_structured_content in their descriptions. E.g. 'fetch_page returns full processed content for LLM context; extract_structured_content uses CSS selectors for precise data extraction; search_documentation queries Cloudflare docs directly.'
• Add pagination to search_documentation. Accept 'limit' (1 - 100, default 20) and 'offset' or 'cursor' parameters. Return a total_count or next_cursor field so agents can iterate through large result sets.
• Document the 'selectors' parameter format in extract_structured_content. E.g. 'selectors (object): Map of field names to CSS selectors. E.g. { "title": "h1.main-title", "price": ".product-price" }. Each selector extracts text content from matching elements.'
• Add idempotentHint and readOnlyHint annotations to tool definitions (MCP spec 2026-07-28). All four tools are read-only, so set readOnlyHint: true on their input schemas.
