Setup for Claude
This page walks you through adding the Kurslog connector to Claude. Total time: under one minute.
Step 1 — Open Connector settings
Visit claude.ai/settings/connectors. You'll see your existing connectors (Google Drive, Gmail, etc.) and at the bottom an "Add custom connector" button.
Step 2 — Add custom connector
Click Add custom connector. A dialog appears asking for the server URL.
Step 3 — Paste the URL
Paste:
https://mcp.kurslog.com/v1/mcpClick Add. Claude will perform the MCP handshake. Since this connector is anonymous, you will not see an OAuth screen — it simply connects.
Step 4 — Verify
Open a new chat in claude.ai and ask:
List supported currencies via Kurslog (locale en, just 5 items)
Claude should call our list_currencies tool and return a short list including usdt-trc20, bitcoin, and similar codes. If you see that, the connector is working.
Troubleshooting
Claude doesn't call any tool
Claude decides autonomously when to use tools. If your question is generic (e.g. "What is Bitcoin?"), it may answer from its own knowledge. Make the question concrete: "using Kurslog tools, what's the best USDT to UAH cash rate in Kyiv?"
"Failed to add connector"
Make sure you pasted the URL exactly: https://mcp.kurslog.com/v1/mcp — including the /v1/mcp suffix. The bare domain will not work.
A tool returns an empty result
This is a valid response, not an error. It means no exchangers match your filters. Try a more common pair (e.g. usdt-trc20 → monobank-uah) or remove the city filter.
Rates look slightly off
Our cache TTL is 60 seconds for rates. Plus, the upstream exchanger may have just updated. Always click through to the exchanger's profile link before transacting.
Connector stopped working
Open Settings → Connectors, find Kurslog, click into it. Check status. If it shows an error, click "Reconnect". If problems persist, contact support@kurslog.com.
What about ChatGPT?
ChatGPT's MCP support is rolling out as of 2026. When ChatGPT supports remote MCP connectors generally, the same URL will work there. Stay tuned on our news page for updates.
