Scored across 1 tool
With only one tool, there is no possibility of confusion between tools. The single tool has a clearly defined purpose.
Only one tool exists, so naming conventions are inherently consistent. The name 'generate_image' is clear and verbs are used appropriately.
The server focuses on image generation, and one tool is reasonable for this narrow scope. While it is minimal, it fully covers the core functionality without unnecessary complexity.
The tool covers all essential aspects of image generation: it offers both local file saving and MCP image content output. No obvious gaps for the intended purpose.
