Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

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

"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
