Currency intelligence,
natively in your AI agent.
CurrencyCore's MCP server gives Claude, Cursor, Windsurf, and any Model Context Protocol client direct access to live exchange rates, PPP data, and 75 years of historical analysis. No glue code. No polling. No stale training data.
No configuration required · OAuth sign-in · Same usage limits as the REST API

}AI agents make expensive currency mistakes.
Language models are trained on snapshot data. By the time your agent answers a currency question, the numbers it knows could be months out of date, with no way to tell you that.
Hallucinated rates
Models confidently cite exchange rates from their training cutoff, sometimes months or years stale. In financial workflows, this is not a UX problem. It is a correctness problem.
Brittle custom wrappers
Teams build one-off tool definitions per model. Each wrapper duplicates auth, error handling, and response shaping, then breaks silently when the upstream API changes a field name.
No history, no analytics
Most rate APIs give you today's snapshot. Agents answering trend questions like "how has EUR moved in 2025?" are left to guess, or send users to a search engine.
One MCP server. Every currency question answered.
CurrencyCore ships a production-ready MCP server with four tools your agents can call immediately: no prompt engineering, no wrapper maintenance, no extra API accounts.
Tool-native, not JSON-wrangling
Agents call convert(from="USD", to="INR", amount=100) and get a typed result back. No JSON parsing, no field extraction, no prompt gymnastics. The MCP layer handles everything the model should not have to think about.
Live rates, not training memory
Rates are sourced from the ECB and refreshed hourly across Cloudflare's global edge network. Every tool call returns the current, verified rate, not what the model last saw during pre-training. Historical data reaches back to 1949.
Org-scoped, metered, auditable
The MCP server authenticates through the same OAuth flow as the REST API. Each tool call counts against your plan's request quota, visible in the dashboard under the MCP panel, so there are no surprise bills and no separate accounts to manage.
Trend analysis, not just spot rates
The analyze_history tool lets agents answer questions like "how did GBP perform against USD over the last decade?" with real data: change percentages, annualized volatility, and period highs and lows, all in a single tool round.
13 tools. Every currency question answered.
Core tools are available on every plan. Analytics tools require Growth plan or higher. The API enforces this at call time.
convert Convert any amount between two currencies at live mid-market rates. Pass ppp=true for purchasing-power-adjusted results with IMF country-level factors.
get_rates Full exchange-rate snapshot against any base currency for any date: today or historical.
get_rates_by_base The same rate snapshot re-expressed against a non-USD base currency.
get_history Historical rate time series for any currency pair over any date window.
analyze_history Change %, annualized volatility, period high and low, and a downsampled trend series over any window. Growth+
analyze_ppp IMF PPP factor change and trend for any country pair over a multi-year window. Growth+
analyze_volatility Rank or compare currencies by annualized volatility over any period. Growth+
analyze_correlation How closely two or more currencies move together. Correlation coefficient over any window. Growth+
analyze_drawdown Peak-to-trough decline and recovery speed for any currency over a chosen period. Growth+
analyze_safe_haven Score currencies on safe-haven characteristics: stability, crisis performance, and reserve status. Growth+
analyze_mean_reversion How strongly a currency tends to revert toward its historical average after a move. Growth+
list_countries All supported countries with their official ISO currency code, so agents resolve "India" to INR:IND without hallucinating codes.
list_currencies All supported ISO 4217 currency codes and their names.
