Getting Started

What is MCP?

The Model Context Protocol (MCP) is an open standard from Anthropic that lets AI assistants like Claude securely connect to external data sources and tools. Think of it as a USB-C port for AI: a single way for an assistant to plug into many systems.

A connector is just a remote MCP server that exposes tools — small JSON-RPC functions the AI can call. The Kurslog connector exposes five read-only tools related to currency exchange.

What this connector does

When Claude has the Kurslog connector enabled, it can autonomously call the following tools to answer a user question:

  • find_best_rate — top 3 exchangers for a pair, optional city for cash.
  • compare_exchangers — broader list (up to 20) with trust and reserves.
  • get_exchanger_profile — vetting info for a single exchanger.
  • find_cities_for_direction — Ukrainian cities with active cash exchange.
  • list_currencies — discover currency codes used as arguments.

Every response includes a freshness disclaimer because cached data can be up to ~5 minutes stale.

What you'll need

  • A Claude.ai account (free or paid).
  • The connector URL: https://mcp.kurslog.com/v1/mcp
  • That's it. No Kurslog account, no API key, no payment.

Quick start

  1. Open claude.ai → Settings → Connectors.
  2. Scroll down to "Add custom connector".
  3. Paste the URL above and click Add.
  4. Open a new chat and try a prompt like "What's the best rate from USDT TRC20 to Monobank UAH right now?"

If Claude calls a tool and returns real numbers — you're set. For the detailed walkthrough with screenshots and troubleshooting, see Setup for Claude.

How does Claude decide when to use a tool?

Claude reads the server's instructions and each tool's description, then chooses tools automatically based on your question. You don't need to invoke tools explicitly. If the topic clearly relates to exchange rates, exchangers, or cash exchange in Ukraine, Claude will reach for Kurslog tools without prompting.

If you want to be explicit, mention "via Kurslog" in your prompt — e.g. "List supported currencies via Kurslog".
