In this video I will show you how to build powerful AI agents using Claude MCP.

For those having issues with this, here is how I resolved it.
1. Initial Setup:
- Installed Node.js using nvm (Node Version Manager) via Homebrew
- Made sure to install nvm first, then Node.js through nvm (order was important)

2. Configuration File:
- Located the proper config file path:
- Had to handle spaces in the path name correctly (this was tricky!)

3. Key Changes That Made It Work:
- Used the full path to npx:
- Added proper environment variables (PATH and NODE_PATH)
- Made sure to use the correct Brave API key (we had to try between two different keys - the "Data for Search" one)
- Created a clean JSON file directly in VS Code instead of using echo commands to avoid formatting issues

4. Final Working Configuration:
```json
{
"mcpServers": {
"brave-search": {
"command": "/Users/yourname.nvm/versions/node/v23.3.0/bin/npx",
"args": [
"-y",
],
"env": {
"BRAVE_API_KEY": "YOUR_API_KEY",
"PATH": "/Users/yourname/.nvm/versions/node/v23.3.0/bin:/usr/local/bin:/usr/bin:/bin",
"NODE_PATH":
}
}
}
}
```

5. Important Steps After Changes:
- Always fully quit Claude Desktop (Command+Q)
- Restart the application
- Verify the MCP server is running with "Brave Search MCP Server running on stdio"

The key lesson was to be methodical and verify each component (Node.js installation, config file location, API key, and proper paths) step by step until we got it working (me and Claude).

I just started implementing and using it yesterday, guys, and now we can really say, "Imagination is the only limit here!"🤩

I had to come back and leave a third comment. I was at work watching this earlier and came straight home and followed this video to a tee and it worked brilliantly. You're one of my favorite YouTubers and I thank you for sharing your knowledge!

For Windows users here is the path:

Just replace username with your user name.
And btw it only works on the paid version of Claude, 3.5 Sonnet.

I went from top 5% to top 2% to top 0.5% just watching this lol.

Incase anyone wants to just replicate!

Please do the following:
- make a simple html page
- create a repository called "new-society-test"
- Push the html page to the "new-society-test" repo
- Add a little css to the html page and then push it up
- Make an issue suggesting we add some more content on the html page
- Now make a branch called feature and make that fix and push the change
- Make a pull request against main with these changes

I love your enthusiasm - you are right in stating the obvious here: a game changer. Well explained.

[OriginalJericho]

Phenomenal value in this video. Thanks for sharing your time, knowledge and insights. I'm with you on seeing what's possible! It's a great time to be alive!

Just an FYI on Windows (Possibly Mac as well) if you download and open the Claude application the 'claude_desktop_config.json' file automatically gets created.
So you'd just need to locate it and open it. Edit: Also in the top left is File < Settings < Developer < Configure which locates & opens .json file

[rennaydorasamy]

Brilliant video David! Excellent, no frills, guide. Thanks!

[ThomasHassettOfficial]

Super keen for your app, keep smashing it brother 🎉

[BodhuDev]

For Windows the path is You can also edit config in the Clause App itself. Although I appreciate your videos, please stop pushing your vectal app, it makes your videos unnecessarily confusing.

[david.walters]

Awesome!

Here is the prompt for everybody to c&p:

Please do the following:
Make a simple HTML page.
Create a repository called "new-society-test."
Push the HTML page to the "new-society-test" repo.
Add a little CSS to the HTML page and then push it up.
Make an issue suggesting we add some more content on the HTML page.
Now make a branch called "feature" and make that fix, then push the change.
Make a pull request against "main" with these changes.

I got the API Key from Brave Search, and updated the config file. I still cannot see the Icon that shows MCP Tools available yet.

Great Video, David. Keep up the amazing work.
