Perplexity

Live currency conversion in your Claude Desktop chat

`convert_currency_pair` lets you calculate exchange rates on the fly without leaving your chat interface. You just ask Claude to convert a price, and it runs the math using live market data instead of relying on outdated training data. This setup runs locally via stdio or connects through a remote URL depending on how you configure your Claude Desktop settings. It handles raw API calls in the background so you get instant fiat conversions during planning sessions.

Enriched currency metadata for deep market context

`get_enriched_currency_data` pulls full currency names, country flags, and regional details straight into Claude Desktop. This means your agent can automatically format financial reports with correct local symbols and regional settings during your research. When you need to build localized pricing tables, this MCP Server feeds Claude the exact data required to map currencies to their respective territories. You don't have to look up ISO codes or format currency symbols manually anymore.

Historical rate analysis using this MCP Server

`get_historical_rates` retrieves past exchange rates for any supported currency pair directly inside your Claude Desktop environment. Your agent can immediately plot historical trends or analyze currency fluctuations over specific dates to help you build financial models. By accessing these historical records, Claude Desktop shifts from a simple conversational client to a capable financial analyst. It uses the raw historical data to run comparative analyses without requiring you to manually import CSV files.
