AllRatesToday MCP Server

MCP server that gives AI coding tools — Claude Code, Cursor, Claude Desktop, and any other Model Context Protocol client — real-time currency exchange rates, historical data, and financial news from AllRatesToday.

Ask your assistant things like:

"What's the current USD to EUR rate?"
"Show me the GBP/JPY rate over the last 30 days."
"Convert 250 USD into CAD using a real rate."
"List every supported currency."

Install

npm install -g @allratestoday/mcp-server

Or run without installing via npx @allratestoday/mcp-server.

Quick setup

Claude Code

claude mcp add allratestoday -- npx -y @allratestoday/mcp-server

Then set your API key:

claude mcp env allratestoday ALLRATES_API_KEY=art_live_xxxxx

Cursor

Edit ~/.cursor/mcp.json (or your project .cursor/mcp.json):

{
  "mcpServers": {
    "allratestoday": {
      "command": "npx",
      "args": ["-y", "@allratestoday/mcp-server"],
      "env": {
        "ALLRATES_API_KEY": "art_live_xxxxx"
      }
    }
  }
}

    "allratestoday": {
      "command": "npx",
      "args": ["-y", "@allratestoday/mcp-server"],
      "env": {
        "ALLRATES_API_KEY": "art_live_xxxxx"
      }
