How do I start using the server?

Install it via npx, add your API key from emojikey.io to the Claude Desktop config, and tell Claude "Set emojikey" on first use. Claude will then automatically use that key in future conversations.

Does the server store any personal information?

No, only the emojikeys are stored online. No user information beyond these keys is kept.

What credentials does it need?

It reads `EMOJIKEYIO_API_KEY`, `MODEL_ID`, `CODE_MODE`, `SUPABASE_URL`, `SUPABASE_ANON_KEY` from the environment. Store these in your client's env block or a secrets manager — never commit them to a repository — and grant the narrowest scope that still covers your use case.
