Overview

Description from the maker (original English)

AI-native crypto trading MCP server — market data, orders, grid strategies & DeFi

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs on your computer
  • Transport: stdio
  • Category: Accounting, finance & tax

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 0 of 1 passed
  • Runs on your computer with your user’s permissions (files, network, apps).
  • The registry lists no key to fill in.

You need

  • npmNode.js installed (for the npx command)

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "openmm": {
      "command": "npx",
      "args": [
        "-y",
        "@qbtlabs/openmm-mcp"
      ]
    }
  }
}

Run this in your terminal

claude mcp add openmm -- npx -y @qbtlabs/openmm-mcp

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "openmm": {
      "command": "npx",
      "args": [
        "-y",
        "@qbtlabs/openmm-mcp"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "openmm": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "@qbtlabs/openmm-mcp"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Common questions

Is Openmm MCP safe?

It passed 0 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.5) reached the registry 8 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

📚 [Documentation](https://docs.openmm.io) · 🤖 [AI Skills Portal](https://agents.openmm.io) · 🔌 [API Reference](https://api.openmm.io)

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

Two Ways to Use

OptionBest ForAPI KeysPayments
Local (npm)Full control, your own keysEncrypted vaultFree
Hosted (mcp.openmm.io)No setup, pay-per-useNot needed for public datax402 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:

ClientConfig 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
ClientWithout vaultWith vault
Claude DesktopAPI keys in envOnly OPENMM_SOCKET
Claude CodeAPI keys in envOnly OPENMM_SOCKET
CursorAPI keys in envOnly OPENMM_SOCKET
WindsurfAPI keys in envOnly 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
PropertyHow
Keys encrypted at restAES-256-GCM + PBKDF2 in ~/.openmm/vault.enc
Keys never in client memoryMCP process only holds socket path
Keys never in config filesNo API keys, no private keys anywhere in config
Process isolationSigning happens in openmm serve, not in the AI agent process
Policy enforcementSpending limits checked before private key is accessed
Memory safetysignAndWipe() — 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

Example Usage

Check BTC price:

"Get me the BTC/USDT ticker on MEXC"

Place an order:

"Buy 0.1 ETH at $2400 on Kraken"

Start grid strategy:

"Start a grid strategy on MEXC for INDY/USDT between $0.10 and $0.15 with 10 levels and $500 total"

Check Cardano token:

"What's the current price of SNEK on Cardano DEXes?"

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
