MCP server for OpenMM — exposes market data, account, trading, and strategy tools to AI agents via any MCP client.

Two Ways to Use

Option	Best For	API Keys	Payments
Local (npm)	Full control, your own keys	Encrypted vault	Free
Hosted (mcp.openmm.io)	No setup, pay-per-use	Not needed for public data	x402 USDC

---

Local Setup

Prerequisites: Node.js 20 or later.

1. Install and configure

npm install -g @qbtlabs/openmm-mcp
openmm-mcp --setup

The setup wizard writes the correct MCP config for your client (Claude Desktop, Claude Code, Cursor, Windsurf). No credentials are stored in config files — only the socket path.

2. Initialize encrypted vault

openmm-init

This creates an encrypted vault at ~/.openmm/vault.enc containing your wallet key and exchange API credentials. You'll set a password, generate (or import) a wallet, and optionally add exchange keys.

3. Start the server

openmm serve

Type your vault password once. The unified socket starts at /tmp/openmm.sock — all MCP clients connect here. No credentials exist in any config file.

Manual configuration

If you prefer to edit config files directly instead of using --setup:

Client	Config file
Claude Desktop	~/Library/Application Support/Claude/claude_desktop_config.json
Claude Code	~/.claude.json
Cursor	.cursor/mcp.json
Windsurf	~/.codeium/windsurf/mcp_config.json

{
  "mcpServers": {
    "openmm": {
      "command": "node",
      "args": ["/path/to/openmm-mcp/dist/index.js"],
      "env": {
        "MCP_TRANSPORT": "stdio",
        "OPENMM_SOCKET": "/tmp/openmm.sock",
        "PAYMENT_SERVER": "https://mcp.openmm.io",
        "X402_TESTNET": "true"
      }
    }
  }
}

Replace /path/to/openmm-mcp with the actual install path. For Claude Desktop, use the full path to node (e.g. from which node) to avoid nvm/PATH issues.

Tip: Run openmm-mcp --setup instead — it writes the correct absolute paths automatically.

No API keys. No private keys. No passwords. Just the socket path.

Without vault (quick start)

You can skip the vault and pass API keys directly in the env block:

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

The vault strengthens every scenario — nothing sensitive exists in any config file, process environment, or client memory.

Client compatibility

Client	Without vault	With vault
Claude Desktop	API keys in env	Only OPENMM_SOCKET
Claude Code	API keys in env	Only OPENMM_SOCKET
Cursor	API keys in env	Only OPENMM_SOCKET
Windsurf	API keys in env	Only OPENMM_SOCKET

All clients connect to the same running openmm serve — one vault, one socket, any client.

Hosted Server with x402 Payments

Connect to mcp.openmm.io — no local installation needed for public data. Pay per tool call with USDC on Base.

How it works

AI Agent (Claude / Cursor / Windsurf)
│  MCP stdio — no keys in config
▼
MCP Client Process
(reads OPENMM_SOCKET — credentials never here)
│  Unix socket /tmp/openmm.sock (mode 0600)
▼
openmm serve — unified vault process
┌──────────────────────────────────┐
│  ~/.openmm/vault.enc             │
│  AES-256-GCM + PBKDF2           │  ← wallet key + exchange keys, one vault
│            │                     │
│  Policy Engine                   │  ← maxPerTx, maxPerDay, allowedChains
│  (checked before key is touched) │
│            │                     │
│  signAndWipe()                   │  ← key used inline, wiped from memory
└──────────────────────────────────┘
│  EIP-3009 signature only
▼
mcp.openmm.io → x402 verification → Base L2 settlement

Security properties

Property	How
Keys encrypted at rest	AES-256-GCM + PBKDF2 in ~/.openmm/vault.enc
Keys never in client memory	MCP process only holds socket path
Keys never in config files	No API keys, no private keys anywhere in config
Process isolation	Signing happens in openmm serve, not in the AI agent process
Policy enforcement	Spending limits checked before private key is accessed
Memory safety	signAndWipe() — key used once, goes out of scope immediately

Payment flow

1. Agent calls a tool
2. Server returns 402 Payment Required with price
3. openmm serve signs EIP-3009 authorization (gasless — no ETH needed)
4. Server submits payment on-chain and returns data

Security

• Vault: AES-256-GCM encrypted at ~/.openmm/vault.enc
• Password: Interactive terminal only — never in any config file, env var, or CLI flag
• Socket: /tmp/openmm.sock mode 0600 — the socket is the authentication boundary
• Policy: Spending limits enforced at the socket before the private key is touched
• Isolation: Private key never enters any MCP client process memory — signing happens in the openmm serve process via IPC

---

Development
