wtf is mcp?

Ratevert MCP is a small server that lets AI assistants and coding tools look up and convert currencies, stocks, exchange traded funds, mutual funds, and cryptocurrencies. It speaks the Model Context Protocol, a standard way for AI agents such as Claude, ChatGPT, or coding assistants to call outside tools during a conversation. Rather than running your own copy, most people connect straight to Ratevert's hosted server at ratevert.com, which requires no API key or account signup. The server exposes four tools. One searches for a specific asset and returns its canonical identity on Ratevert. Another fetches the current one to one exchange rate between two assets along with a link back to the source page. A third converts a specific amount of one asset into another and reports the exact rate, a rounded value, how fresh the data is, and a source link. The fourth compares one starting asset against up to three others at once. Public use of the hosted server is rate limited, and each comparison request can include at most four total assets. Developers who want to run their own copy locally need Node.js 20 or newer. Setup is a short sequence of installing dependencies, copying an example environment file, and starting the server, after which it listens on a local address by default. The project includes automated tests, a release verification script, and an optional smoke test that can be pointed at a live deployment. The README is explicit that Ratevert MCP is informational only. It does not offer investment, trading, tax, or payment advice, and market data returned by its tools may be delayed or temporarily unavailable.
