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 🙏

Wallet Agent

MCP server for Web3 wallet interactions in AI assistants like Claude Code and Cursor. Supports mock wallets for testing and real wallets via private key import.

Quick Start

claude mcp add wallet-agent bunx @shanev/wallet-agent

Verify with /mcp in Claude Code.

Core Features

  • Wallets: Connect, sign messages, send transactions
  • Chains: Switch networks, add custom EVMs
  • Tokens: Transfer ERC-20/721, check balances
  • Contracts: Read/write via Wagmi or built-in ABIs

Usage Examples

Basic Flow

"Connect to 0xf39Fd6e51aad88F6F4ce6aB8827279cffFb92266"
"Check my balance"
"Send 0.1 ETH to 0x70997970C51812dc3A010C7d01b50e0d17dc79C8"
"Switch to Polygon"

Token Operations

"Transfer 100 USDC to 0x..."
"Get my USDT balance"
"Approve DAI spending for 0xDEX..."

Custom Chains

"Add Base mainnet"
"Add local Anvil chain"
"Switch to Base"

Real Wallets (Development Only)

⚠️ NEVER paste private keys in chat!

Option 1: Environment Variable

# When adding server
claude mcp add wallet-agent bunx @shanev/wallet-agent -e WALLET_PRIVATE_KEY=0x...

# Or in shell
export WALLET_PRIVATE_KEY="0x..."

Then: "Import private key from WALLET_PRIVATE_KEY"

Option 2: Secure File

echo "0x..." > ~/.wallet-key
chmod 600 ~/.wallet-key

Then: "Import private key from ~/.wallet-key"

Workflow

  1. "Set wallet type to privateKey"
  2. "Connect to my wallet"
  3. Use normally
