ToraSEO MCP exposes 11 SEO analysis tools via STDIO. All tools have basic descriptions (50-150 chars) and single-parameter schemas (url: string). However, critical gaps undermine production readiness: (1) Parameter descriptions are minimal or absent, most just repeat 'The URL to [action]' without explaining expected format, constraints, or error cases. (2) Output schemas are not documented in the visible code, LLMs cannot predict return structure or plan downstream calls. (3) No error handling guidance, tools fail silently or return raw HTTP errors. (4) Tool names lack clarity on scope: 'analyze_*' tools overlap conceptually (analyze_meta, analyze_canonical, analyze_headings all inspect page structure). (5) No pagination, batching, or result limits documented. Baseline: 549 production tools average 194-char descriptions with 100% param coverage; ToraSEO averages ~80 chars with ~10% param descriptions. This is a functional but immature implementation.

• Document output schema for each tool. Example for 'scan_site_minimal': {status: number, title: string, h1: string, description: string, responseTime: number, errors: string[]}. This enables LLMs to chain tools and extract fields.
• Expand parameter descriptions to 50-150 chars. Example: 'url (string, required): Full URL to scan (http:// or https://, max 2048 chars). Returns error if domain unreachable or response timeout >30s.'
• Add error handling guidance to tool descriptions. Example: 'If robots.txt is missing, the tool returns {allowed: true, reason: "no robots.txt found"}. If the domain is unreachable, returns {error: "domain_unreachable", suggestion: "verify domain spelling or try a different URL"}.'
• Consolidate overlapping analyze_* tools. Merge analyze_meta, analyze_canonical, analyze_headings into a single 'analyze_page_structure' tool with an optional 'components' enum parameter (meta|canonical|headings|all, default=all).
• Add pagination and result limits. For tools returning lists (analyze_links, analyze_content, detect_stack), document max results (e.g., 'returns up to 100 links; use offset/limit for pagination') and include total_count in response.
