Installing Claude MCP with the Second Brain OS

You also get access to running your own AI agents inside of Claude. This utilizes what’s known as the Claude Model Context Protocol (MCP).

You’ve probably heard this term—it’s very hyped up and buzzing right now. MCP is essentially a simple way for all AI models across the world, especially Claude, to communicate with tools that already exist. Things like Notion, Todoist, Monday, Jira, Slack—whatever. All of those tools can easily work with your AI agent because of MCP.

The Second Brain OS makes this process even easier and smoother.

Today I’m giving you access to the Second Brain OS MCP server, which connects directly to your Claude and allows you to have an AI agent running as per your customization, right inside of Claude.

The end result is similar to what you saw in the custom GPT—the process is just a bit different.

Step 1: Find Your Setup Instructions

First, head into your email and find the one that says “Added Feature: Claude MCP for you.” Click the button.

Alternative: Go to your dashboard and click on “Setup Link” next to the Claude icon. This opens the page with all the installation instructions.

Step 2: Download Claude Desktop

Very important: Make sure you have the Claude desktop application downloaded and installed.

Head to this link: Claude AI Download and download the application for your platform.

Key point: By default, it will highlight what your computer is using:

  • Mac machine → highlights Mac version
  • Windows ARM64 → highlights ARM64 version
  • Other Windows → highlights standard Windows version

Just click the button that is white and download that one, then install it.

Important: After installing Claude, make sure to force quit Claude completely. Go to the app and press “Quit”—Claude needs to be shut off after you download it.

Step 3: Install Node.js

Next, Google “Node.js.” If you’ve never heard of it, that’s perfectly fine.

What is Node.js? It’s a way for JavaScript (a programming language) to run on your computer. All programming languages require what’s known as an “engine” to run and execute code. They don’t work on your computer by default—they need that engine to be present first.

Think of it like this:

  • UV is the most popular engine for Python
  • Node.js is the most popular engine for JavaScript

Head over to nodejs.org/en and press “Install.” Just like Claude did, it will automatically highlight the one you need and pick the best suitable package for you.

Click to download the Node.js package, then:

  1. Open the downloaded file
  2. It will ask for permission to continue
  3. Press “Continue” through the prompts
  4. Press “Agree” to start installation
  5. Use default options—no customization needed, just keep it as standard installation

Step 4: Connect Second Brain OS to Claude

Now that you have both Claude desktop and Node.js installed, you can connect your Second Brain OS to Claude for a fully functioning, powerful AI agent.

Open Your Command Interface

Windows users: Press the Windows key and type “cmd” – this opens PowerShell (a black window where you can enter commands)

Mac users: Press Spotlight (Command + Space), type “Terminal” and press Enter

Fun fact: This is the OG way of using a computer! Before fancy UIs and apps, everything was done through commands. This is what you see in action movies when people are “hacking.”

Run the Installation Command

  1. Head back to the Second Brain OS Claude MCP page
  2. I strongly recommend Option 1
  3. Copy the entire command (from start to finish)
  4. Paste it into your terminal (Control+C or Command+C to copy, then paste)
  5. Press Enter

That’s it! The command will:

  • Verify you’re a Second Brain OS user
  • Run the installation process
  • Update your Claude desktop to connect with Second Brain OS

Step 5: Restart Claude

Once installation is complete, you’ll see: “Installation is successful. Please quit Claude and restart the Claude app.”

  1. Quit the terminal (Command+Q or just close it)
  2. Open Claude again

Step 6: Access Your AI Agent Tools

Once Claude opens, here’s where all your Second Brain OS tools live:

  1. Click the little icon (if you hover, it says “Search and Tools”)
  2. At the bottom, you’ll see all external tools you’ve added
  3. These are called MCP servers (Model Context Protocol servers)
  4. Click on the Second Brain OS server
  5. It shows all available tools from that server
  6. Make sure to enable all of these

Step 7: Test Your Setup

Let’s do the same test we did with the custom GPT:

Me: “What workflows do I have access to?”

Claude shows exactly what information goes to the Second Brain OS server and the exact response that comes back—I love this transparency!

Claude: Returns all available workflows

Me: “For the rapid punch hooks, get all the prompts.”

Claude fetches all those prompts—and it’s reasonably faster and often more intelligent than base ChatGPT models

Me: “Crawl this video [paste URL] and apply both prompts.”

Real Results Example

Here’s what it generated:

What I thought would make me productive:

  • The perfect note-taking app with all the features
  • A complex system with tags and folders
  • AI that could read my mind and organize everything automatically

What actually makes me productive:

  • One simple capture method that works everywhere
  • Zero friction between idea and storage
  • My context guiding AI, not the other way around

Everyone chases the first, but usually ends up disappointed.

Not bad, right? I’d argue these tweets are already better than what you’d get from GPT (though that’s subjective and a matter of taste).

Why I Prefer Claude

I have a minor bias here—I strongly prefer Claude over ChatGPT because it’s:

  • Way more powerful
  • Way more efficient
  • Better at writing—responses are closer to what I like to see, nuanced and detailed
  • Better at coding (both are good, but Claude edges out slightly)

The only con: It’s a desktop app, not a website. But once you get used to the desktop app, you won’t think twice about it.

Next Level: Integration with Other Tools

Just like with the custom GPT, this all happened really fast—one message, second message, third message, that’s all it took!

You can start posting or pushing this content to Notion, Airtable, or whatever tool you use to store your writing. You never have to worry about losing great content or ideas.

Personal recommendation: I have the Notion integration, and you should look into it. It pushes content to Notion in a formatted way—headings are there, bullets are there, nothing breaks. This saves me tons of time because I hate the friction of copying/pasting between ChatGPT or Claude into Notion and dealing with formatting issues.

With the Notion integration, you get the Second Brain OS Notion template that gives you a complete end-to-end workflow from rough ideas and audience research to fully published content.

The Power of AI Agents

This is the power of having an AI agent right on your laptop/desktop. Whether you prefer Claude or GPT, do whatever works best for you.

You should have 2-3 workflows right now to play with, and you can always:

  • Go to the workflow marketplace for more
  • Purchase an AI agent (which brings more workflows)
  • Subscribe to my coaching program

The more workflows you accumulate, the stronger your systems will be. The better systems you have, the more scalable you’ll be.

Quick Business Insight

If you intend to open an agency or build a writing/coding business, good systems are crucial. Good systems are all about having workflows in place. Then you can bring in people who aren’t the most skilled and still run those workflows to get the same results.


I hope you’re as excited as I am to have Claude MCP or OpenAI Custom GPTs as your agents without paying for another subscription!

Let me know if you have any questions—you can always hop on a call, message me, or ask my AI agent whatever you need.
