BOB Currency Rates Connector for Claude

Last Updated: August 8, 2026

A free, public MCP (Model Context Protocol) server with live and historical exchange rates for 178+ currencies, hosted by BOB Tools. No account, no API key, no authentication — just add the URL and ask Claude about currency rates:

https://api.bob.tools/mcp-currency

What you can do

Current rates: "What's the EUR and GBP rate right now?" — current rate, previous-day rate, and percentage change, relative to USD.
Historical data: "How did the yen move over the last 90 days?" — daily aggregates (min/max/avg/open/close) or full hourly data points.
Conversions and analysis: Claude combines the rates with your numbers — convert amounts, compare trends, build tables and charts.

How to connect

In Claude (web, desktop, or mobile):

Open Settings → Connectors and choose Add custom connector.
Enter the server URL: https://api.bob.tools/mcp-currency
That's it — no sign-in step. Enable the connector in a chat and ask about rates.

The same URL works in any MCP-compatible client — for example Claude Code (claude mcp add --transport http bob-currency https://api.bob.tools/mcp-currency).
