This MCP server has severe definition quality issues across nearly all tools. 23 tools are defined in search-proxy.cjs, but the source code provided does NOT include that file, only TypeScript service files. This means tool definitions cannot be verified from the provided source. The tools appear to be inferred from the endpoint responses and the summary provided. For 18 of 23 tools (GetProducts, GetDetailedInventory, GetInventoryStatus, GetLowStockProducts, GetSalesData, GetTotalRevenue, GetSalesByCategory, GetDailySummary, GetContentTypesSummary, GetPricesWithoutBaseItem, GetLatestStatistics, GetPluData, GetArticlesWithIngredients, GetDocuments, GetCollections, CheckSupermarketHealth, CheckThirdApiHealth, CheckSystemHealth), NO input schemas are visible, only descriptions. For FindArticlesByName and FindArticleByContentKey, minimal schemas are shown with single string parameters but no output schemas documented. The multi_tool_use tool has a complex input schema but no output schema. Descriptions are present for all tools but are generic, single-sentence summaries (e.g., 'Retrieve products from the supermarket SQL server plugin') that lack context on WHEN to use them, what prerequisites exist, or what the response structure is. No parameter descriptions beyond name and type for the 2 - 3 tools with params. No documented output schemas for ANY tool. Error handling guidance is absent. These are serious gaps that will cause LLM tool selection errors and mid-chain failures.

• Publish the search-proxy.cjs file so tool definitions can be reviewed. Ensure each tool registration includes: name (verb_noun), description (100 - 300 chars answering what/when/why), input schema (JSON Schema with types and descriptions for each param), output schema (documented structure of the response).
• Expand all tool descriptions from single sentences to full paragraphs. Example: GetProducts should say 'Retrieve products from inventory. Call this to find available items, check pricing, or discover what's in stock. Returns product name, ID, price, stock quantity, and category. Pagination supported via limit and offset params.'
• Add input schemas for all 18 tools that lack them. At minimum, specify: type (object), properties (each param with type, description, and constraints), required (array of param names).
• Document output schema for every tool. Use a response_schema or similar field that shows the structure: {type: 'object', properties: {...}, required: [...]}. Example for GetProducts: {products: [{id, name, price, stock, category}], total_count, next_offset}.
• Add parameter descriptions to FindArticlesByName, FindArticleByContentKey, SearchDocuments. Example: 'name: Article name or partial name to search for. Case-insensitive. Min 2 chars, max 255 chars. Returns exact and fuzzy matches.'
• Replace multi_tool_use with direct tool exposure. Remove the meta-tool wrapper and let the client MCP select tools directly. If tool routing is needed, implement it server-side and expose the underlying tools with clear names.
