Compatible with every major AI agent and IDE
What is the Real-Time Currency Exchange MCP Server?
LLMs only know the dollar exchange rate from their last training data cutoff. This MCP solves that by connecting your AI directly to the Frankfurter API (European Central Bank data), turning it into a real-time Forex machine.
Superpowers
- Real-Time Conversion: Ask the AI to convert entire spreadsheets or budgets from USD to EUR based on today's exact opening rate.
- Time-Travel Economics: Need to audit an invoice from 2018? The AI can fetch the exact historical exchange rate from that specific day to ensure perfect accounting.
- Zero Friction: No authentication required. Just connect the MCP and your AI instantly understands 30+ global fiat currencies.
Built-in capabilities (2)
It uses the European Central Bank reference rates. Accepts 3-letter ISO currency codes (e.g., USD, EUR, BRL, JPY). Converts an amount from one currency to another using exact real-time or historical exchange rates
Gets a list of current exchange rates against a base currency
