Give your AI real exchange rates

Connect any MCP client — Claude Desktop, Claude Code, Cursor, Codex, or your own agent — to daily-synced Norges Bank rates: 38 currencies against NOK, history back to ~1980, conversion and charting tools. Nothing to install or host, and free to start.

Three steps

1Add Currency Exchange to your MCP client

For Claude Code, one command:

claude mcp add currency --transport http https://currency.publifye.pro/mcp

For Claude Desktop (or any client), add this to claude_desktop_config.json:

{ "mcpServers": { "currency": { "url": "https://currency.publifye.pro/mcp" } } }

2Log in once

The first time your AI calls the service, a browser window opens to sign in at Publifye. Create a free account (or log in), approve access, and you're connected — no key to copy or paste. Your session refreshes silently from then on, and your plan travels with your login.

Your plan and purchases are always visible in your Publifye account. Currency Access buyers also get a personal API key there — revealed once (rotate any time for a fresh one) — for scripts and clients without browser login: send it as an X-API-Key header to the same endpoint. Login and key share the same monthly allowance rules.

3Ask anything

Every tool is self-documenting — your AI discovers them automatically. Try:

  • "Convert 100 USD to NOK"
  • "What was the EUR rate against NOK on 15 January 2020?"
  • "Chart the USD/NOK rate over the last year"

Tools: get_rate, convert, list_currencies, get_rates_range, get_all_rates, service_status.
