## What it does

This MCP server connects Claude Code to the eonik app on a Mac. It can prepare size variations from a master design, adjust individual elements, and check creatives against project rules such as logo use, typeface, required copy, and file-size limits. You can review the results before anything becomes final. Creation, edits, and sending all require your approval.

You need the eonik app on a Mac with macOS 15+ and Apple silicon, plus an API key. The local bridge runs with `npx -y eonik-mcp` and uses `EONIK_API_KEY`, `EONIK_API_URL`, and `EONIK_BRAND_ID`. When more than one brand is connected, `EONIK_BRAND_ID` is required; eonik will not pick a client’s brand for you. Keep the app open while using the server. It cannot manage ad campaigns or write to Meta, TikTok, or Google Ads.

## Requirements
- Needs: Node.js (commands run via npx)
- Environment variables: `EONIK_API_KEY`, `EONIK_API_URL`, `EONIK_BRAND_ID` — keys and tokens: ask the human for the values, never commit them or put them in shared files.
