OpenMM MCP

What it is

A trading server for AI agents, with an unusual amount of attention paid to where the keys live. A separate vault process holds your wallet key and exchange credentials encrypted on disk; the MCP process the client launches knows only a socket path, so no credential ever enters a config file, the agent's environment, or the client's memory.

What you get

• 15 tools across market data, account, trading, Cardano DEX and strategy
• Market data by exchange and symbol: real-time price with bid, ask, spread and volume, order-book depth, recent trades with a buy/sell summary, and candlestick data — get_ticker, get_orderbook, get_trades, get_ohlcv, list_exchanges
• Account reads: balances across all assets or one, and open orders across the account or by symbol — get_balance, list_orders
• Order placement and cancellation — limit or market orders, cancel one by id, or cancel everything on a pair — create_order, cancel_order, cancel_all_orders
• Cardano DEX data: an aggregated token price across DEXes, and liquidity-pool discovery with a minimum-liquidity filter — get_cardano_price, discover_pools
• Grid trading as a managed strategy rather than a loop you write: start it between a lower and upper price with a level count and total amount, check its status, stop it with or without cancelling its orders — start_grid_strategy, get_strategy_status, stop_strategy
• A policy engine checked before the private key is touched at all — per-transaction and per-day spend caps, and an allowed-chain list
• A hosted option priced per call, where reads and writes carry different prices and payment settles in USDC on Base without needing gas
• One running vault serving every client, so several MCP clients share the same unlocked process rather than each holding credentials

Requirements

Node.js 20 or later for the local path. Install @qbtlabs/openmm-mcp globally and run the setup command, which writes the client config for Claude Desktop, Claude Code, Cursor or Windsurf. Then initialize the vault — it creates an encrypted file in your home directory holding a generated or imported wallet key plus any exchange credentials — and start the vault process, unlocking it with your password once per session. From then on the only value in any config is the socket path. A quick-start path exists that skips the vault and puts exchange keys directly in the client's env block. For the hosted server there is no local install at all: connect to the streamable-HTTP endpoint and pay per call. The package is 1.0.13 in package.json.
