Coinrebate MCP server

@coinrebate/mcp-server

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 claudedesktopconfig.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 --help for command-specific usage. The existing npx -y @coinrebate/mcp-server command still starts the stdio MCP server.

6 Available Tools

Also available on the hosted endpoint: recommendfeeoption — instead of a table it returns

a single verdict ("the lowest effective fee for a user in is X"), together with the

assumptions behind it and what is deliberately not modelled, and abstains when the upstream data

is unreliable or the top venues are genuinely tied. It is currently exposed only through the remote

MCP endpoint https://coinrebate.vip/api/mcp, which needs no install. It will land in this npm

package in a later release.

Compliance — Built In

Every tool that returns exchange recommendations supports an optional country parameter (ISO 3166-1 alpha-2). When provided, results are filtered against the CoinRebate compliance matrix.
