Agents guess FX numbers or force you to tab out to rate websites while coding pricing and checkout logic.
Who is it for?
Indie SaaS or ecommerce builders adding multi-currency display, conversion, or reporting with Claude Code or Cursor.
Skip if: Teams that need payment processing, hedging, or compliance-grade treasury systems without a separate FX provider evaluation.

- Multi-currency lookup answers grounded in AllRates Today API
- Configurable API base URL for non-default endpoints
Recommended MCP Servers
Journey fit
Exchange-rate lookups are integrated during product build when apps need external financial data, not during initial idea research. This is an MCP bridge to AllRates Today—classic third-party API integration work in the build phase.
How it compares
FX data MCP integration, not a payments skill or spreadsheet plugin.
