What problem does it solve?
Manually checking ČNB tables breaks flow when you need dated, audit-friendly FX for invoices and multi-currency pricing inside the agent.
Who is it for?
Indie SaaS or agencies in the Czech Republic (or CZK books) who want agents to cite ČNB rates for pricing and bookkeeping.
Skip if: Builders with no CZK exposure who only need generic crypto or retail FX feeds without Czech regulatory sourcing.
What do I get? / Deliverables
Your agent returns official CZK rates on demand so quotes, cost models, and accounting entries use the same authoritative numbers.
- Daily and historical official CZK versus EUR, USD, and 30+ currency rates inside agent tool calls
- Accounting-ready FX figures cited from ČNB via MCP
Recommended MCP Servers
Journey fit
Canonical shelf is Validate because solo builders set prices and quote in EUR/USD against CZK before and while selling; rates also support ongoing books in Operate. Pricing is where daily and historical FX against 30+ currencies directly affects quotes, plans, and revenue math.
How it compares
Official-rate MCP integration, not a spreadsheet skill or payment processor.
