This MCP server has 6 tools with schemas present but significant quality gaps. Tool names are reasonable (browseStore, getPricing, comparePackages, purchaseProduct, setupYext, setupWordpress) but lack action-verb consistency (camelCase mixed with weak verbs like 'browse' instead of 'list'). Descriptions are present but minimal (10-50 chars) and lack LLM-optimized context about when to use each tool. Parameter schemas are declared with types and basic descriptions, but descriptions are frequently trivial ('optional product category filter' does not explain what categories exist or how they affect results). No output schemas are documented, the server provides no guidance on what fields agents should expect from tool responses. Error handling is declared as 'errorReporting: true' but no evidence exists in the source code of actionable error messages, recovery paths, or categorization. The purchaseProduct and setupYext/setupWordpress tools accept sensitive business data (addresses, phone numbers, payment method IDs) but lack clear security documentation around credential handling or audit trails. No tool annotations (readOnlyHint, destructiveHint, idempotentHint) are present despite WRITE tools (purchaseProduct, setupYext, setupWordpress) that modify state. Overall, the server has skeleton structure but lacks production-grade polish in description depth, output documentation, and error guidance.

• Document output schemas for all tools. At minimum, describe what fields are returned for browseStore (e.g., products: [{id, name, price, category, ...}]), getPricing (e.g., {productId, tier, monthlyPrice, annualPrice, discount}), and purchaseProduct (e.g., {orderId, status, confirmationEmail, nextSteps}).
• Expand tool descriptions to 80-150 chars. Example for browseStore: 'List all available products and packages, optionally filtered by category (e.g., email, hosting, seo) or price tier (budget, standard, premium). Use this to help users discover what we offer before requesting details or purchasing.'
• Add descriptions to every parameter explaining constraints and valid values. Example: 'category: optional product category to filter by (valid options: email, hosting, seo, security, analytics; pass multiple by comma-separating). If omitted, returns all products.'
• Add tool annotations: mark purchaseProduct, setupYext, setupWordpress with destructiveHint=true and idempotentHint=false (since payment/domain setup is non-idempotent); mark browseStore, getPricing, comparePackages with readOnlyHint=true.
• Implement and document error handling for each WRITE tool. Define what errors can occur (e.g., 'Invalid payment method', 'Tier not available in region', 'Domain already taken') and what the agent should do (e.g., 'Retry with a different payment method', 'Suggest alternative tiers', 'Recommend alternative domain').
• For purchaseProduct and setupYext, add a note in security documentation that PII (addresses, phone numbers, emails) must never be logged as parameters. Use server-side configuration injection or vault-based secrets, and return only safe confirmations to the agent (e.g., 'Order placed successfully' without echoing the address back).
