On the MCP Server page, open the Claude Desktop tab. If you have Claude Pro, Max, Team or Enterprise, you can connect without a token or any file setup: copy the URL https://app.adseditor.app/mcp, go to Settings and Connectors in Claude, add the connector and authorize on the login screen that opens in your browser. That's it, and it takes about 30 seconds. On Claude's free plan, use one of the alternatives on the same tab (these use a token and, for some options, require Node.js). After setup, fully quit Claude and reopen it for the Ads Editor tools to appear.
