5 Steps to Set Up Filesystem MCP on Mac
1Verify Node.js Installation
Open Terminal and enter:
If a version number is displayed, you’re ready to proceed. If not, you’ll need to install Node.js first.
2Open Claude Desktop’s Configuration File
- Launch Claude Desktop
- From the menu bar, select “Claude” → “Settings…”
- Click on “Developer” in the sidebar
- Click the “Edit Config” button
This will open the configuration file (claude_desktop_config.json).
3Edit the Configuration File
Copy and paste the following into the opened configuration file:
Note: Replace “your_username” with your Mac username. Example: /Users/john/Desktop
You can add or modify the folders you want to grant access to!
Important Security Note
Be cautious about which folders you allow Claude to access. It’s recommended to avoid granting access to folders containing sensitive personal information.
4Restart Claude Desktop
Once you’ve saved the configuration, completely quit Claude Desktop (“Quit Claude”) and then restart it.
5Test the Setup
After restarting, if you see a “🔨 (hammer)” icon at the bottom of the input field, the setup was successful!
Try giving Claude these test instructions:
- “Create a file named poem.txt on my Desktop and write a short poem”
- “List the files in my Downloads folder”
The first time Claude accesses each location, you’ll be prompted with an “Allow” dialog – make sure to grant permission!
Troubleshooting
If it’s not working, check the following:
- Did you completely restart Claude?
- Are there any syntax errors in your JSON configuration?
- Are the directory paths correct?
- Check the log files (~/Library/Logs/Claude/) for errors:
The logs will help identify where the problem might be occurring.
