This server has severe definition quality issues. Tool 1 (execute_skill_action) has no visible input schema in the source code, only a description. Tool 2 (route_international_return) has a partial schema with only 2 parameters documented, but the description is vague and does not explain WHEN to use it or what the output structure is. Neither tool has documented output schemas. Parameter descriptions are minimal (parcel_location and destination_hub lack context on valid values, formats, or constraints). No error handling guidance. No tool annotations. The server appears to be a stub implementation with hardcoded mock responses rather than a production-ready MCP server.

• Add explicit input schema to execute_skill_action with required parameters, types, and descriptions. Currently no schema is visible.
• Replace example values in route_international_return descriptions with enum constraints. Define valid hub names (EU_CENTRAL, NA_EAST, APAC_WEST, etc.) and location formats (ISO country codes or city names).
• Document the output schema for both tools. route_international_return returns routing_id, origin, destination_hub, customs_duty_reclaim_eligible, duty_reclaim_amount_usd, recommerce_disposition, co2_saved_kg, logistics_cost_reduction_pct, formalize this in the tool definition.
• Expand tool descriptions to 100-200 characters explaining WHAT each tool does, WHEN to use it, and what it returns. E.g., 'Route international return parcels to optimal destination hubs. Use this when you have a parcel location and need to determine the best hub for cost/duty optimization. Returns routing ID, duty reclaim eligibility, and disposition.'
• Add error handling guidance: 'If location is not recognized, try with ISO country code (e.g., GB instead of UK). If no hub is available, contact logistics support.'
