For a one-off CSV, often yes. Prism is for when you need the same cleaning logic every time, with undo, exportable pipelines, and guardrails that stop train/test leakage — without shipping your dataset through chat context.

Official support is macOS only. The website, setup wizard, and menu bar companion are built for Mac users running Claude Desktop.

No. The MCP server runs locally on your machine. Your datasets stay in folders you control, like ~/datasets.

Look for the Prism icon in your menu bar. It lights up when Claude has connected to the MCP server process.

Click the menu bar icon and choose Disable Server, or run dataset-analysis-mcp-disable in Terminal.

Run dataset-analysis-mcp-doctor. It prints exactly what is missing and where to look in the install log.
