# Ratevert MCP

A public read-only MCP server for finding assets and converting currencies, stocks, crypto, ETFs and funds. Useful when an agent needs an exact rate plus a citable source.

## What it does

Four tools ship with the server. `search_assets` resolves a canonical Ratevert asset, `get_rate` gives the current one-unit rate for a pair along with a canonical pair URL, `convert_amount` handles a stated amount and returns the exact rate, a rounded display value, freshness and a source URL, and `compare_assets` puts one source asset against up to three targets. A comparison request tops out at four assets total: one source plus three targets.

Agents connect over remote Streamable HTTP at `https://ratevert.com/api/mcp`. No API key is involved, and public traffic is rate-limited. Claude takes a single terminal command; Cursor and GitHub Copilot need the server declared in the client config. Running it locally needs Node.js 20 or newer and npm 10 or newer — `npm ci`, copy `.env.example` to `.env`, then `npm start`. The default bind is `127.0.0.1:3010`, serving `http://127.0.0.1:3010/mcp`.

Behind a reverse proxy, keep `RATEVERT_MCP_TRUST_PROXY` scoped to that one known proxy and have the proxy itself replace the forwarding headers it receives — otherwise a client address is trivial to spoof. Treat the output as reference material: quotes can lag or go missing, and nothing here executes a trade.

## When to use it
- resolve a canonical ID for a currency, stock or crypto asset
