This MCP server exhibits significant quality gaps across all definition dimensions. Tool names lack clear action verbs, descriptions are either missing or minimal, and input schemas are either completely absent or severely underspecified. The server operates as a Turkish-language car search interface with 4 tools, but 3 of them (sql_sorgusu_calistir, tablolari_listele, tablo_yapisi_goster) expose raw database operations without adequate safety guardrails. The primary tool (araba_ara) has an extremely verbose description (400+ chars) that violates brevity guidelines, and most parameters lack type information in the source schema. Error handling is not evident. Security is a critical concern: the sql_sorgusu_calistir tool accepts arbitrary SQL strings, creating injection risks.

• Add explicit JSON Schema input definitions for all tools. sql_sorgusu_calistir must reject parameters entirely (or switch to pre-approved parameterized queries); tablolari_listele and tablo_yapisi_goster need proper optional/required field declarations.
• Replace text-based enum descriptions in araba_ara with formal 'enum' constraints in JSON Schema. Instead of 'yakit: "Yakıt tipi (gaz, benzin, dizel, hibrit, elektrik)"', define: {"enum": ["gaz", "benzin", "dizel", "hibrit", "elektrik"]}.
• Reduce araba_ara description to 150-200 characters. Current description (400+ chars) wastes tokens. Suggested: 'Search for cars by brand, model, price range, year, mileage, location, fuel, transmission, condition, type, color, and sorting options.'
• Implement input validation with actionable error messages. E.g., if yakit is invalid, return: 'Invalid fuel type: "xyz". Valid options: gaz, benzin, dizel, hibrit, elektrik.' This guides LLM self-correction.
• Document output schemas for all tools. Include examples of response structure (e.g., araba_ara returns {cars: [{id, marka, model, fiyat, yil, ...}], total_count, next_page_token?}).
• Remove or restrict sql_sorgusu_calistir. Arbitrary SQL execution is a critical security risk. If needed, switch to pre-approved parameterized queries only, or remove and rely on araba_ara for searches.
• Add per-tool error handling that tells the LLM what to do on failure. E.g., if araba_ara returns no results: 'No vehicles found matching your criteria. Try broadening price range or removing filter constraints.'
