Critical failures across all dimensions. The single tool 'execute_skill_action' has no visible input schema, no parameter descriptions, and a generic description that violates baseline standards. The mcp_server.py file contains only a JSON print statement with no actual MCP protocol implementation, no tool registration, no request/response handling, no schema definitions. Tool definitions are inferred from client.py (not the MCP server itself), triggering the hard cap rule. This is not a functional MCP server.

• Implement actual MCP protocol in mcp_server.py: parse JSON-RPC requests, dispatch to tool handlers, return structured responses with proper error handling.
• Define execute_skill_action with a complete JSON Schema input specification: list all parameters (e.g., buyer_company, catalog_sku_count), their types, descriptions, and constraints (enums, ranges, patterns).
• Rename tool to a specific verb_noun pattern: 'configure_procurement_portal' or 'create_marketplace_configuration', not 'execute_skill_action'.
• Expand tool description to 100-200 chars: explain what it configures, when to call it, and what fields are returned (e.g., 'Configures a B2B procurement portal for an enterprise buyer. Returns portal_configuration_id, approval hierarchy levels, and integration status.').
• Add parameter descriptions: 'buyer_company (string): Name of the enterprise buyer (e.g., Schneider Industrial Group). catalog_sku_count (integer, 1-500000): Number of SKUs in the supplier catalog.'
