3. Ask Claude a currency question
Restart Claude Desktop and ask: "What is the current USD to EUR rate?" Claude calls the convert tool and returns a live answer.
13 live tools. Every currency question answered.
Claude calls the right tool automatically. You ask in plain English and get a verified answer.
Convert currencies
convert(from='USD', to='INR', amount=500) returns a live rate, no guessing.
Historical rates
Any date back to 1949. Ask "What was the EUR rate in 2008?" and Claude fetches the exact ECB value.
PPP analysis
Ask "What is $99 worth in India in purchasing power terms?" and get the IMF-backed PPP equivalent.
Volatility
Which currencies are most stable right now? Claude ranks them with real annualized data.
Correlation
"Are EUR and GBP correlated?" Returns the Pearson coefficient over any window.
Country lookup
Claude resolves "India" to INR:IND without hallucinating currency codes.
