🎯 Pro Tips for Better Prompts

✅ Good Prompts:

• Be specific: "Calculate the derivative of x³ + 2x² with respect to x"
• Include units: "Convert 100 kilometers to miles"
• Provide context: "Find the monthly payment for a $200,000 loan at 4.5% APR for 30 years"
• Specify precision: "Calculate π to 10 decimal places"

❌ Avoid:

• Vague requests: "Do some math"
• Missing parameters: "Calculate compound interest" (missing principal, rate, time)
• Ambiguous units: "Convert 100 degrees" (Celsius to Fahrenheit? Degrees to radians?)

🔧 Configuration Hints:

• If you get "tool not available" errors, you may need to enable additional tool groups
• Use health_check to see which tools are currently available
• Check the configuration guide for enabling specific mathematical capabilities

🔧 Troubleshooting

Common Issues

"Tool not available" errors

• Cause: Tool group not enabled
• Solution: Enable the required tool group (e.g., CALCULATOR_ENABLE_ADVANCED=true)
• Check: Use server logs to see which tools are currently enabled

Import/dependency errors

• Cause: Missing dependencies (numpy, scipy, sympy)
• Solution: Reinstall with pip install p6plab-mcp-calculator[dev]
• Check: Verify virtual environment activation

Performance issues

• Cause: Large computations or insufficient resources
• Solution: Adjust CALCULATOR_MAX_COMPUTATION_TIME and CALCULATOR_MAX_MEMORY_MB
• Check: Monitor server logs for resource usage

Currency conversion not working

• Cause: Feature disabled by default for privacy
• Solution: Set CALCULATOR_ENABLE_CURRENCY_CONVERSION=true
