This MCP server has significant definition quality gaps. All 14 tools have descriptions in Turkish and basic parameter schemas, but lack the rigor required for production use. Parameter descriptions are minimal or missing type context. No output schemas are documented. Error handling guidance is absent. Tool naming follows verb conventions but descriptions are often too brief to guide LLM tool selection effectively. The server demonstrates basic structure but falls short of patterns expected in production-grade agent tools.

• Add explicit output schemas for every tool. Example for get_bus_lines: 'Returns {"lines": [{"line_number": int, "name": string, "direction": string, "stops_count": int}], "total": int}'.
• Expand parameter descriptions to include constraints and valid ranges. Example: 'line_number (integer, 1-9999): ESHOT bus route number. Call get_bus_lines to discover valid numbers.'
• Add WHEN/WHY context to tool descriptions. Example for search_routes: 'Use this to find multi-leg itineraries between two addresses, including transfers. For real-time bus positions, call get_real_time_arrivals instead.'
• Document error recovery paths. Example: 'If line_number is invalid, get_bus_schedule returns {"error": "not_found", "message": "Bus line 999 does not exist. Use get_bus_lines() to list valid lines.", "available_lines": [...]}'.
• Add limit and offset parameters to list tools (get_bus_lines, get_metro_stations, get_tramway_stops). Recommend pagination to prevent context window overflow.
• Provide enums for constrained parameters. Example for get_tramway_stops, line param: use enum ["karsiyaka", "konak", "cigili"] instead of free-form description.
• Translate descriptions to English, or provide English alongside Turkish, to support international agent deployments.
• Add tool annotations. Mark all tools with readOnlyHint=true (all are safe read operations). This signals to agents that these calls are safe to retry without side effects.
• Document which tools return IDs needed by other tools. Example: search_routes returns stop_id → use that in get_real_time_arrivals. This enables predictable tool chaining.
