useWebMCP is a browser-based WebMCP framework, not a traditional MCP server. Tools are defined in Vue composables with explicit schemas and descriptions. However, critical gaps undermine production readiness: (1) Tool definitions are scattered across example files (useCoffeeTools.ts, app.vue) with inconsistent schema completeness, some tools lack additionalProperties constraints; (2) Parameter descriptions are minimal (10-30 chars) and lack actionable guidance on formats, ranges, or dependencies; (3) No output schemas documented anywhere, LLMs cannot predict response structure; (4) Error handling is absent, tools throw generic errors without recovery guidance; (5) Composition issues: search_catalog and search_products are near-duplicates; reorder_product and add_to_cart overlap; (6) No security model visible, no permission gates, audit trails, or secret injection patterns. The framework itself is well-structured (TypeScript, Vue 3, Nuxt integration), but tool definitions fall short of production standards.

• Document output schemas for all tools. E.g., search_catalog should return {products: [{id, name, price, category}], total_count}. This enables LLMs to chain tools correctly.
• Expand parameter descriptions to 50-100 chars with actionable constraints. E.g., 'quantity: Number of items to add (1-20; defaults to 1 if omitted)' instead of just 'Number of items (1-10)'.
• Consolidate search_catalog and search_products into a single search_products tool with a clear description of what it searches (names, categories, descriptions, tags).
• Consolidate reorder_product and add_to_cart into a single add_to_cart tool that accepts both product IDs and quantities, with clear parameter descriptions.
• Add error handling that returns actionable messages. E.g., if productId is invalid, return 'Product not found. Call search_products() to find valid IDs.' instead of a generic error.
