Agent readability score
Strengths
- Some tools (e.g., 'km-to-mi') have clear primary purpose
- Consistent parameter naming across all tools
Weaknesses
- Server name 'Kilometers to miles' contradicts 30+ unrelated tools
- Tool descriptions provide no usage context or conditions
- All parameters are optional with no clear required fields
- Massive tool overlap (15+ URL-related tools)
- No error handling documentation for any tool
