OpenMM — Open-Source Market Making for AI Agents

OpenMM is an open-source market making framework — multi-exchange support, grid strategies, real-time market data, and automated trading. One CLI for everything.

GitHub: https://github.com/3rd-Eye-Labs/OpenMM MCP Server: https://github.com/QBT-Labs/OpenMM-MCP Docs: https://deepwiki.com/3rd-Eye-Labs/OpenMM

What is OpenMM?

• Multi-Exchange — MEXC, Gate.io, Kraken, Bitget
• Grid Trading — Automated grid strategies with dynamic spacing, sizing, and volatility adjustment
• Market Data — Tickers, orderbooks, recent trades across all exchanges
• Order Management — Limit/market orders, cancel, list open orders
• Cardano DEX — Pool discovery, aggregated prices via Iris Protocol
• CLI + MCP — Use via command line or as MCP server for AI agents
• Open Source — MIT licensed, fully customizable

Quick Start

Option A: CLI

# Install
npm install -g @3rd-eye-labs/openmm

# Set exchange credentials as environment variables
export MEXC_API_KEY="your_api_key"
export MEXC_SECRET="your_secret_key"

# Check balances
openmm balance --exchange mexc

# Get ticker price
openmm ticker --exchange mexc --symbol BTC/USDT

# Start grid trading (dry run first)
openmm trade --strategy grid --exchange mexc --symbol INDY/USDT --dry-run

Option B: MCP Server

Run npx @qbtlabs/openmm-mcp to start a local MCP server over stdio. This exposes all 13 tools to any MCP-compatible client.

{
  "mcpServers": {
    "openmm": {
      "command": "npx",
      "args": ["@qbtlabs/openmm-mcp"],
      "env": {
        "MEXC_API_KEY": "your_key",
        "MEXC_SECRET": "your_secret"
      }
    }
  }
}

Only include env vars for exchanges you want to use.

Option C: As Library

import { OpenMM } from '@3rd-eye-labs/openmm';

const mm = new OpenMM({
  exchange: 'mexc',
  apiKey: process.env.MEXC_API_KEY,
  secret: process.env.MEXC_SECRET
});

const orderbook = await mm.getOrderbook('BTC/USDT');

---

Environment Setup

Exchange credentials are configured via environment variables — keys are stored locally and never sent to the server. Add them to your .env file or export them in your shell:

# MEXC (API key + secret)
MEXC_API_KEY=your_mexc_api_key
MEXC_SECRET=your_mexc_secret_key

# Gate.io (API key + secret)
GATEIO_API_KEY=your_gateio_api_key
GATEIO_SECRET=your_gateio_secret_key

# Bitget (API key + secret + passphrase set when creating the API key)
BITGET_API_KEY=your_bitget_api_key
BITGET_SECRET=your_bitget_secret_key
BITGET_PASSPHRASE=your_bitget_passphrase

# Kraken (API key + secret)
KRAKEN_API_KEY=your_kraken_api_key
KRAKEN_SECRET=your_kraken_secret_key

Symbol Format

• Use standard format: BTC/USDT, ETH/USDT, INDY/USDT, ADA/EUR, BTC/USD
• The CLI automatically converts to exchange-specific format
• Kraken supports both USD/EUR fiat pairs and USDT pairs

Core Tools

Balance & Portfolio

Check account balances on any connected exchange. Query each exchange separately — there is no cross-exchange aggregate command.

# Get all balances
openmm balance --exchange mexc
openmm balance --exchange gateio
openmm balance --exchange bitget
openmm balance --exchange kraken

# Get specific asset balance
openmm balance --exchange mexc --asset BTC
openmm balance --exchange mexc --asset USDT
openmm balance --exchange kraken --asset ADA
openmm balance --exchange kraken --asset EUR

# JSON output (useful for scripting)
openmm balance --exchange mexc --json
openmm balance --exchange bitget --json

Options:

• -e, --exchange <exchange> — Exchange to query (required)
• -a, --asset <asset> — Specific asset to query (optional)
• --json — Output in JSON format

Market Data

Real-time prices, orderbooks, and trade history. Use --symbol with the standard BASE/QUOTE format. Kraken uses fiat pairs like ADA/EUR and BTC/USD alongside crypto pairs.

Ticker — current price, bid/ask, spread, volume:

# MEXC
openmm ticker --exchange mexc --symbol BTC/USDT
openmm ticker --exchange mexc --symbol ETH/USDT --json

# Bitget (Cardano tokens)
openmm ticker --exchange bitget --symbol SNEK/USDT
openmm ticker --exchange bitget --symbol BTC/USDT --json

# Kraken (fiat pairs)
openmm ticker --exchange kraken --symbol ADA/EUR
openmm ticker --exchange kraken --symbol BTC/USD --json

Order Book — bid/ask depth:

# MEXC - BTC/USDT with default 10 levels
openmm orderbook --exchange mexc --symbol BTC/USDT

# Bitget - top 5 levels for SNEK
openmm orderbook --exchange bitget --symbol SNEK/USDT --limit 5

# Kraken - ADA/EUR with 10 levels
openmm orderbook --exchange kraken --symbol ADA/EUR --limit 10

# Gate.io - JSON output
openmm orderbook --exchange gateio --symbol BTC/USDT --json

Recent Trades — latest executions with buy/sell breakdown:

# MEXC - default 20 trades
openmm trades --exchange mexc --symbol BTC/USDT

# Bitget - 50 trades for SNEK
openmm trades --exchange bitget --symbol SNEK/USDT --limit 50

# Kraken - ADA/EUR trades
openmm trades --exchange kraken --symbol ADA/EUR

# Gate.io - JSON output
openmm trades --exchange gateio --symbol ETH/USDT --json

Options (shared across ticker, orderbook, trades):

• -e, --exchange <exchange> — Exchange to query (required)
• -s, --symbol <symbol> — Trading pair symbol (required)
• -l, --limit <limit> — Number of levels/trades (orderbook default: 10, trades default: 20)
• --json — Output in JSON format

Grid Trading

The grid strategy places buy and sell orders at intervals around the current center price. As price oscillates, orders fill and the grid automatically recreates — capturing the spread on each cycle. Total orders = levels x 2.

# Start grid with defaults (5 levels, 2% spacing, $50 per order)
openmm trade --strategy grid --exchange mexc --symbol INDY/USDT

# Dry run — preview the grid without placing real orders
openmm trade --strategy grid --exchange bitget --symbol SNEK/USDT --dry-run

# Custom grid configuration
openmm trade --strategy grid --exchange mexc --symbol INDY/USDT \
  --levels 5 \
  --spacing 0.02 \
  --size 50 \
  --max-position 0.6 \
  --safety-reserve 0.3

# Geometric spacing — tighter near center, wider at edges
openmm trade --strategy grid --exchange kraken --symbol BTC/USD \
  --levels 10 \
  --spacing 0.005 \
  --spacing-model geometric \
  --spacing-factor 1.5 \
  --size-model pyramidal \
  --size 50

# Volatility-based spread adjustment — grid widens in volatile markets
openmm trade --strategy grid --exchange mexc --symbol INDY/USDT \
  --levels 10 \
  --spacing 0.005 \
  --spacing-model geometric \
  --spacing-factor 1.3 \
  --size-model pyramidal \
  --size 5 \
  --volatility

# Volatility with custom thresholds (tighter sensitivity)
openmm trade --strategy grid --exchange kraken --symbol SNEK/EUR \
  --levels 5 \
  --spacing 0.01 \
  --size 5 \
  --volatility \
  --volatility-low 0.01 \
  --volatility-high 0.03

# Load configuration from a JSON profile
openmm trade --strategy grid --exchange gateio --symbol SNEK/USDT \
  --grid-profile ./profiles/balanced-geometric.json

Cardano DEX Integration

OpenMM integrates with Cardano DEX liquidity pools via the Iris Protocol. Supported tokens: INDY (Indigo Protocol), SNEK (Snek Token), NIGHT (Midnight), MIN (Minswap).

Prices are calculated by fetching TOKEN/ADA from on-chain DEX pools (weighted by TVL), then multiplying by ADA/USDT from CEX price feeds (MEXC, Coingecko) to produce a TOKEN/USDT price.

Discover liquidity pools:

# Find all pools for a token
openmm pool-discovery discover INDY

# Top 5 pools for SNEK
openmm pool-discovery discover SNEK --limit 5

# Filter by minimum TVL
openmm pool-discovery discover INDY --min-liquidity 50000

# Show all pools (ignore limit)
openmm pool-discovery discover NIGHT --show-all

Get live prices from pools:

openmm pool-discovery prices NIGHT
openmm pool-discovery prices SNEK
openmm pool-discovery prices INDY

List supported tokens:

openmm pool-discovery supported

Compare DEX vs CEX prices:

openmm price-comparison --symbol SNEK
openmm price-comparison --symbol INDY

Safety Rules

Always dry-run first

Before executing any grid strategy, preview the grid to see what orders will be placed:

openmm trade --strategy grid --exchange mexc --symbol INDY/USDT --dry-run

Confirm before execution

For AI agents using MCP:

1. Always show the trade plan — display what will be executed
2. Get explicit confirmation — never auto-execute without user approval
3. Use dryRun: true — the MCP start_grid_strategy tool defaults to dry-run mode

Risk management

Grid strategy has built-in risk controls:

• --max-position 0.6 — Use max 60% of balance for trading (default: 80%)
• --safety-reserve 0.3 — Keep 30% as safety reserve (default: 20%)
• --confidence 0.8 — Require 80% price confidence before trading (default: 60%)

Total allocation is automatically capped regardless of the size model used. The grid recreates when orders are filled and adjusts to significant price movements (configurable via --deviation).

Tips for Agents

• Check balances first — always run openmm balance --exchange <ex> before trading
• Use --dry-run — preview grid strategies before placing real orders
• Use BASE/QUOTE format — e.g. BTC/USDT, ADA/EUR, SNEK/USDT
• Query each exchange separately — there is no cross-exchange aggregate command
• Handle rate limits — exchanges have API limits, space out requests
• Store credentials securely — use environment variables, never commit .env files
• Respect minimum order values — MEXC/Gate.io/Bitget: 1 USDT, Kraken: 5 EUR/USD
• Use --max-position and --safety-reserve — built-in risk controls for grid strategies
• Bitget requires passphrase — set via BITGET_PASSPHRASE env var (created when generating the API key)
• Use --json for parsing — all commands support --json for structured output
