asterdex-mcp

Model Context Protocol (MCP) server for Aster DEX — a Binance-compatible perpetual futures DEX on-chain.

Features

• Account — balance, positions, open orders
• Trading — place/cancel/modify orders (market, limit, stop, TP/SL)
• Market Data — klines/OHLCV, 24h ticker, orderbook, exchange info
• Analysis — RSI, MACD, Stochastic, EMA, Bollinger Bands, signals
• Auth — EIP-712 typed data signing (delegation model)

Quick Start

# Using uvx (recommended — no install needed)
uvx asterdex-mcp

# Or install globally
pip install asterdex-mcp

Wallet Setup Guide

Aster DEX uses a delegation model with two wallets:

Wallet	What it is	Purpose
Main Wallet	Your primary wallet (e.g. MetaMask)	Holds funds, manages API permissions
Agent Wallet	A separate wallet for automation	Signs trades on your behalf

Step 1: Create an Agent Wallet

Generate a new Ethereum-compatible wallet for the agent. This wallet will sign transactions but never holds funds.

# Using ethers.js / viem / any wallet generator
# Or use this quick Python snippet:
python3 -c "
from eth_account import Account
acct = Account.create()
print(f'Address: {acct.address}')
print(f'Private Key: {acct.key.hex()}')
"

Save the output — you'll need both the address and private key.

Step 2: Set Up API Access on Aster

1. Go to Aster DEX and connect your main wallet
2. Navigate to Settings → API Management
3. Click Create API Key
4. Enter your agent wallet address when prompted
5. Important: Enable the following permissions:
   • ✅ Perps Trading (required for placing orders)
   • ✅ Enable IP restriction (recommended for security)
6. Whitelist your server/agent IP address
7. Confirm and sign the transaction from your main wallet

Step 3: Get Your Credentials

You need three values:

ASTER_WALLET=0x...    # Your main wallet address (the one on Aster)
ASTER_SIGNER=0x...    # Your agent wallet address (from Step 1)
ASTER_PRIVATE_KEY=0x...  # Your agent wallet private key (from Step 1)

⚠️ Never share your private key. The agent wallet should have NO funds — it only signs messages.

Step 4: Install & Configure

Claude Code

# Add the MCP server
claude mcp add asterdex -- uvx asterdex-mcp \
  -e ASTER_PRIVATE_KEY=0xYOUR_AGENT_PRIVATE_KEY \
  -e ASTER_WALLET=0xYOUR_MAIN_WALLET_ADDRESS \
  -e ASTER_SIGNER=0xYOUR_AGENT_WALLET_ADDRESS

Verify with:

claude mcp list

OpenClaw

Add to your OpenClaw MCP config (~/.openclaw/mcp.json or project-level):

{
  "mcpServers": {
    "asterdex": {
      "command": "uvx",
      "args": ["asterdex-mcp"],
      "env": {
        "ASTER_PRIVATE_KEY": "0xYOUR_AGENT_PRIVATE_KEY",
        "ASTER_WALLET": "0xYOUR_MAIN_WALLET_ADDRESS",
        "ASTER_SIGNER": "0xYOUR_AGENT_WALLET_ADDRESS"
      }
    }
  }
}

Hermes Agent

Add to ~/.hermes/config.yaml under mcp_servers:

mcp_servers:
  asterdex:
    command: uvx
    args:
    - asterdex-mcp
    env:
      ASTER_PRIVATE_KEY: '0xYOUR_AGENT_PRIVATE_KEY'
      ASTER_WALLET: '0xYOUR_MAIN_WALLET_ADDRESS'
      ASTER_SIGNER: '0xYOUR_AGENT_WALLET_ADDRESS'
    enabled: true
    timeout: 30

Then restart: hermes gateway restart

Claude Desktop

Add to ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):

{
  "mcpServers": {
    "asterdex": {
      "command": "uvx",
      "args": ["asterdex-mcp"],
      "env": {
        "ASTER_PRIVATE_KEY": "0xYOUR_AGENT_PRIVATE_KEY",
        "ASTER_WALLET": "0xYOUR_MAIN_WALLET_ADDRESS",
        "ASTER_SIGNER": "0xYOUR_AGENT_WALLET_ADDRESS"
      }
    }
  }
}

Cursor

Add to .cursor/mcp.json in your project root (or ~/.cursor/mcp.json globally):

{
  "mcpServers": {
    "asterdex": {
      "command": "uvx",
      "args": ["asterdex-mcp"],
      "env": {
        "ASTER_PRIVATE_KEY": "0xYOUR_AGENT_PRIVATE_KEY",
        "ASTER_WALLET": "0xYOUR_MAIN_WALLET_ADDRESS",
        "ASTER_SIGNER": "0xYOUR_AGENT_WALLET_ADDRESS"
      }
    }
  }
}

Step 5: Verify

Ask your AI agent to run get_balance — if it returns your USDT balance, you're good to go.

Tools

Tool	Description
get_balance	Account balance and margin summary
get_positions	Open positions with PnL
get_open_orders	Pending orders (optional symbol filter)
place_order	Place market/limit/stop/TP/SL orders
cancel_order	Cancel order by ID
cancel_all_orders	Bulk cancel all open orders
set_leverage	Set leverage per trading pair
get_exchange_info	Pairs, precision, leverage limits

Examples

See examples.md for natural language prompting examples — account, analysis, trading, and combined workflows.

How Auth Works

Aster DEX uses EIP-712 typed data signing (same as Hyperliquid). Instead of API keys with HMAC:

1. Your agent wallet signs each request with EIP-712
2. Aster verifies the signature against the signer address you registered
3. The main wallet is included in the signed data so Aster knows whose account to act on

This means:

• No API key/secret pairs to manage
• Agent wallet can't steal funds (it has none)
• You can revoke access anytime from Aster's API settings

Tech Stack

• Python 3.11+
• mcp — MCP Python SDK
