CoinRithm MCP server

Let your AI practice crypto trading with fake money on CoinRithm and show you the results.

CoinRithm is a practice trading platform where you can try crypto spot, futures, and prediction markets using pretend money. This MCP server connects your AI assistant to CoinRithm so it can place practice trades and check your results for you. It is handy if you want to test trading ideas without risking any real money.

What is an MCP server? The 30-second version

On its own, your AI can only chat. An MCP server is a small helper that gives your AI a new skill or a connection to another service. This one connects your AI to CoinRithm, a practice trading site. Once connected, your AI can look up prices, place pretend trades, and check your practice portfolio when you ask.

What this MCP server does

You ask your AI something like "get a quote for Bitcoin" or "open a practice trade." Your AI sends that request through this helper to CoinRithm. CoinRithm does the work on your practice account and sends back the numbers. Your AI then explains what happened in plain words in the chat. Every trade uses virtual money, so nothing real is at stake.

Flow diagram: you ask your AI “Get a quote for Bitcoin”, the CoinRithm MCP server connects it to CoinRithm, and you get back answer in chat.

Before you start

What you need

A CoinRithm account
A CoinRithm API key (you create it in your profile; it looks like crk_live_...)
An MCP client like Claude Desktop, Claude Code, Cursor, or Codex
For the local option: Node.js installed on your computer

Good to know

Everything here uses pretend money, so nothing real is at risk, but your AI can still place and close practice trades on your account, so start with a read-only key until you are comfortable.
