Install on Mac

Prism automates server install and Claude config. A few steps still need you — listed clearly below.

Recommended · Easy setup

Download Prism.app

The menu bar app shows a checklist, progress for each automated step, and macOS notifications so you always know what is happening.

Download for Mac

Before you start

Have these ready before clicking Set up Prism.

Download the DMG and run Install Prism.command

Open the DMG and double-click Install Prism.command (recommended). It copies Prism to Applications and clears macOS download warnings automatically.

Or drag Prism to Applications manually

If macOS says “Prism is damaged”, see the fix below — this is normal for unsigned apps.

Install Python 3.10+

Prism uses Python to run the MCP server. Download from python.org if you do not have it yet.

python.org/downloads

Install Claude Desktop

Prism configures Claude for you, but Claude must already be on your Mac.

claude.ai/download

Prism does this automatically

After you click Set up Prism — no Terminal needed.

✓ Install dataset-analysis-mcp from PyPI
✓ Write your Claude Desktop MCP config
✓ Copy a sample CSV to ~/datasets
✓ Run an automatic health check

You still need to do this

Prism cannot do these for you — the app will remind you when setup finishes.

Click “Set up Prism” in the app

One button inside Prism — no Terminal. The app shows progress and sends notifications for each step.

Quit Claude Desktop (Cmd+Q) and reopen it

Claude only picks up new MCP servers after a full quit — not just closing the window.

Paste the starter prompt in Claude

Load ~/datasets/sample_sales.csv and run a data quality check

✦

Starter prompt

Copy this into Claude after you reopen it.

Load ~/datasets/sample_sales.csv and run a data quality check

Advanced · Manual setup

Terminal (pip)

For developers who prefer the command line.

pip install dataset-analysis-mcp && dataset-analysis-mcp-setup

Step 1. Run: pip install dataset-analysis-mcp && dataset-analysis-mcp-setup

Step 2. Run dataset-analysis-mcp-doctor and confirm green checks

Step 3. Quit Claude Desktop completely (Cmd+Q)

Step 4. Reopen Claude and try a starter prompt

macOS says “Prism is damaged and can’t be opened”

This happens because Prism is not Apple-notarized yet. macOS blocks downloaded apps that are not signed by a registered developer. Your app is fine — macOS is being cautious.

Quick fix (Terminal):

xattr -cr /Applications/Prism.app

Or: System Settings → Privacy & Security → Open Anyway after the first blocked launch.

Starting in v0.1.4, the DMG includes Install Prism.command which does this for you.

Advanced: manual Claude config
