No install snippet on purpose. A working MCP config is a command, its arguments and an environment block — the last two are where API keys live, so this catalogue never stores them and cannot publish them. Follow the link above for the authors' own instructions.
The only crypto MCP server built on real exchange referral relationships — not just market data.
Give your AI agents instant access to permanent trading fee discounts (up to 50% off, varies by exchange) on Binance, OKX, Bybit, Bitget, Gate.io, Hyperliquid, and Aster DEX. Your users keep the discount on every trade, forever. Zero infrastructure, zero exchange negotiations.
Why this exists
Other crypto MCP servers (CCXT, Binance, exchange-specific) give you read-only market data.
CoinRebate gives your AI agent something more valuable: the ability to recommend exchanges to users with permanent fee discounts baked in — backed by real affiliate agreements with each exchange (the tools return the current code at runtime, so nothing goes stale). When a user signs up via your AI agent, they get a permanent fee discount on every trade.
We negotiated the referral deals with exchanges. You build the AI agent. Your users keep the savings.
Quick Start
Claude Desktop
Add to claude_desktop_config.json:
{
"mcpServers": {
"coinrebate": {
"command": "npx",
"args": ["-y", "@coinrebate/mcp-server"]
}
}
}
Cursor / Cline / any MCP client
Same npx -y @coinrebate/mcp-server invocation.
LangChain / CrewAI / AutoGen
from langchain_mcp_adapters import MCPClient
client = MCPClient(command="npx", args=["-y", "@coinrebate/mcp-server"])
Command Line
Install once, then call only the tool you need. Human-readable output is the default; add
--json for scripts and agents.
npm i -g @coinrebate/mcp-server
coinrebate fees binance
coinrebate compare --purpose spot --country CN
coinrebate referral binance --country CN
coinrebate cost binance --volume 100000 --type spot
coinrebate compliant --country US --purpose spot
Run coinrebate <command> --help for command-specific usage. The existing
npx -y @coinrebate/mcp-server command still starts the stdio MCP server.
