Frequently Asked Questions

Is it free?

Yes. No API key, no signup, no payment. Kurslog is funded by the main consumer site at kurslog.com, and the MCP connector reuses that same public data layer.

How fresh are the rates?

Rates are cached for 60 seconds at the MCP layer, and the upstream Kurslog backend caches its own queries for 30 seconds. So in the worst case rates can be ~90 seconds stale by the time Claude relays them. Each response includes an explicit disclaimer field reminding the user to verify on the exchanger's site before transacting.

Do you log my Claude conversations?

No. The connector receives only the tool name and arguments — not your prompts or Claude's replies. We log: timestamp, source IP, tool name, sanitized arguments, response latency. Logs are retained for 30 days. Full details: Privacy Policy.

Can I use this connector from my own code, not Claude?

Yes — it's a standard remote MCP server. Any MCP client that speaks Streamable HTTP can talk to https://mcp.kurslog.com/v1/mcp. That includes Claude Desktop, Claude Code, custom agents using the official MCP Python or TypeScript SDKs, and (eventually) ChatGPT.

Why is it region-specific (Ukraine / Eastern Europe)?

Kurslog's core dataset is exchange offices serving the Ukrainian market and its diaspora — both online swaps to Ukrainian banks and physical cash exchange in Ukrainian, Polish, and other regional cities. We don't have meaningful coverage outside this region, and we'd rather be accurate about a niche than provide thin global data.

Will you support ChatGPT?

The connector itself is a standard remote MCP server, so when ChatGPT broadly supports custom remote MCP connectors, the same URL will work. As of early 2026 ChatGPT's MCP support is still rolling out. We'll publish a setup guide on kurslog.com/news when it becomes possible.

How do I report a bug or a wrong rate?

E-mail support@kurslog.com or use our contact page. Please include: the exact tool name, the arguments you passed (or the prompt that triggered it), and the response you got. Screenshots help.

Is the source available?

The MCP server itself is not open source yet. The data it exposes is the same that powers the public site at kurslog.com — so you can also see all of it without the connector. If you'd like to integrate with Kurslog data at a deeper level (custom dashboards, white-label widgets), contact partnerships.

Are there rate limits?

60 requests per minute per IP at the nginx layer. Combined with per-tool caching, you should never hit it through normal Claude usage. If you do, you'll receive HTTP 429 — back off and retry.

Does the connector execute trades or move money?

No, never. It is strictly read-only. It surfaces public rate and exchanger data — nothing more. To actually execute an exchange, the user must visit the chosen exchanger's site and transact there directly.
