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 🙏

Readme

Product Brain MCP (@productbrain/mcp)

Give your AI agent your product's memory. Read the Chain, capture decisions, and write back — from Claude Code, Claude Desktop, Cursor, or any MCP client.

Requirements: Node 18+, and an API key from Product Brain Settings, API Keys.

Install

Pre-GA, always pin the beta tag:

npx -y @productbrain/mcp@beta

Connect your client

Claude Code

claude mcp add productbrain \
  -e PRODUCTBRAIN_API_KEY=pb_sk_your_key_here \
  -- npx -y @productbrain/mcp@beta

Claude Desktop

claude_desktop_config.json:

{
  "mcpServers": {
    "productbrain": {
      "command": "npx",
      "args": ["-y", "@productbrain/mcp@beta"],
      "env": {
        "PRODUCTBRAIN_API_KEY": "pb_sk_your_key_here"
      }
    }
  }
}

Cursor

~/.cursor/mcp.json — same command / args / env block as above.

Configuration

| Variable | Required | Default | |---|---|---| | PRODUCTBRAIN_API_KEY | yes | — your API key. Workspace, user and scope come from it on the server. | | CONVEX_SITE_URL | no | Product Brain Cloud. Point at another deployment (a *.convex.site URL, not *.convex.cloud). | | PRODUCTBRAIN_URL | no | Alias for CONVEX_SITE_URL. | | MCP_DEBUG | no | Set to 1 for verbose logs on stderr. |

See .env.mcp.example in this package for the annotated list.

What your agent gets

Tools for orientation, search, capture, entry and relation management, collections, labels, workflows, and session tracking. The agent reads what governs the work before it acts, and writes decisions and tensions back as it learns them.

Prefer the terminal? @productbrain/cli exposes the same Chain as pb.
