Curren$or 💱

A sleek currency converter you can self-host in seconds. Compare up to 5 currencies at once with live exchange rates, swap them around, search through 50 options. One HTML file, zero setup.

→ Try it live · → Use it inside Claude or ChatGPT

Use it inside Claude or ChatGPT

Currensor also runs as a plugin (an MCP server) for Claude and ChatGPT. Ask for a conversion in plain words and a live Currensor card appears right in the chat. Change the amount on the card and every currency updates instantly.

Plugin address:

https://currensor-mcp.currensor-mcp.workers.dev/mcp
AppHow to add it
ClaudeSettings → Connectors → Add custom connector → paste the address → choose No sign-in
ChatGPTSettings → Plugins → Developer mode on, then + → Create custom MCP server → paste the address → No Auth

Then ask: "Use Currensor to convert 250 CAD to INR, EUR and JPY."

  • Live mid-market rates for 166 currencies, refreshed daily, with a backup rate feed
  • No sign-in, no API key, nothing about you stored. The server keeps only anonymous daily counts (which app, which currency pair) to see if people find it useful
  • Free and open source: the server is in mcp/ and runs on Cloudflare Workers

Why I Built This

I'm building tools with AI and learning in public. I can't write code from scratch (yet), but I can design, think through problems, and ship real products by collaborating with AI. Every project teaches me something new.
