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 that lets AI hosts employ agents on Functor wallets

Readme

@functornetwork/mcp

MCP server that lets AI hosts (Claude Code, Claude Desktop, Cursor, Continue, any MCP client) operate Functor agentic wallets — creating wallets, granting scoped session keys, executing transactions, and verifying authority on-chain — without ever custodying private keys. Keys are resolved by name from the OS keychain (preferred), a local file, or env vars, and never appear in tool arguments or results.

Install

# Claude Code
claude mcp add functor -- bunx @functornetwork/mcp

# or run directly
bunx @functornetwork/mcp

Requires Bun (the server runs via the bun shebang).

Network

The chain is selected at startup via the FUNCTOR_CHAIN environment variable:

| FUNCTOR_CHAIN | Chain | Relay | | --- | --- | --- | | bnb-testnet (default) | BNB Smart Chain Testnet (97) | Functor hosted (https://relay.functor.sh) | | sepolia | Ethereum Sepolia (11155111) | Porto hosted (https://rpc.porto.sh) |

# Operate on Sepolia instead of the BNB default
FUNCTOR_CHAIN=sepolia bunx @functornetwork/mcp

One server process serves one chain — restart with a different FUNCTOR_CHAIN to switch. BNB testnet requires a local relay to be running; see the Running the relay guide.

Tools

  • Identity: about_functor
  • Bootstrap: create_wallet
  • Inspect: list_wallets, wallet_balance, wallet_verification, verify_authorization, list_sessions
  • Operate: wallet_execute, grant_session, revoke_session, session_execute

Built on @functornetwork/agentic-wallet.
