failed to get MCP service: %w

Error message

failed to get MCP service: %w

What it means

Thrown by GetMCPServiceResources when mcpServiceRepo.GetByID fails to load the MCP service before listing its resources. A persistence-layer error (connectivity, timeout); distinct from the not-found case which is handled separately.
