How to install xlsx-for-ai

xlsx-for-ai is published on npm as xlsx-for-ai, and it is listed in the official MCP Registry. These steps assume it runs as a local stdio server, which is the usual setup.

Check the README. Confirm the start command and note any API keys or environment variables it needs (pass them with -e KEY=value or an env block). You need Node.js for npx.

Add it to Claude Code from a terminal:

claude mcp add xlsx-for-ai -- npx -y xlsx-for-ai

Or add it to Cursor or Claude Desktop in .cursor/mcp.json or claude_desktop_config.json:

{
  "mcpServers": {
    "xlsx-for-ai": {
      "command": "npx",
      "args": [
        "-y",
        "xlsx-for-ai"
      ]
    }
  }
}

Restart the client and check it. Run claude mcp list, or open the client's MCP settings, and confirm xlsx-for-ai and its tools are listed. The install guide covers VS Code and Codex.
