Ezkielyna Audio MCP

An MCP server that gives your AI assistant text to speech (saved as local MP3/WAV files) and speech to text from local audio files, including Indonesian, through the Ezkielyna API. Works in Claude Desktop, Claude Code, Cursor, OpenCode and any other MCP client that runs local stdio servers.

Examples:

• "Transcribe ~/Downloads/voice-note.ogg (it's in Indonesian) and summarise it in three bullet points."

• "Read this product description aloud in Indonesian and save it as promo-kopi."

🇮🇩 Bahasa Indonesia: lihat bagian di bawah.

• One file, no dependencies: only Node.js 18 or newer. No npm install.

• Audio is saved in one folder and existing files are never overwritten.

• Paid calls are capped per session and the API key is never printed.

Requirements

1. Node.js 18+ (node -v). Get the LTS from nodejs.org.

2. An Ezkielyna API key whose group includes the audio models. The simplest choice is Auto. According to the public price list (checked 11 Nov 2026) the speech models are enabled for the Standard and Premium groups, and edge-tts also for Hemat; the Media group (image and video) did not list them. list_audio_models shows the groups per model and, with a key set, whether your key can use each one. Buy API Credit at ezkielyna.store/beli-api-key (from $0.5, QRIS/DANA/GoPay/USDT), redeem it under Wallet at api.ezkielyna.store, then create a key under API Keys.

Tools

Price examples (public price list, 11 Nov 2026, list prices in USD): edge-tts $1 per 1M characters, so a 4,000-character text is about $0.004; whisper-large-v3 is listed at $12 per 1M audio tokens and billed by audio length (see Usage Logs on api.ezkielyna.store for the exact charge).

Voices

The voice is passed to the OpenAI-format POST /v1/audio/speech endpoint as you give it. Defaults, taken from the model descriptions in the public price list (11 Nov 2026):

If the model returns a different format than requested (for example edge-tts only returns MP3), the file is saved with the extension of the audio it really contains and the answer says so.

Install

With npx (recommended): nothing to install. The configs below run npx -y ezkielyna-audio-mcp.

From source:

git clone https://github.com/EzkielynaGroup/ezkielyna-audio-mcp.git
cd ezkielyna-audio-mcp
node --test test/        # optional: local mock server, no network, no cost

Then use "command": "node" with "args": ["/full/path/to/ezkielyna-audio-mcp.mjs"] instead of npx.

Windows: if the app cannot start npx, use "command": "cmd" with "args": ["/c", "npx", "-y", "ezkielyna-audio-mcp"]. Write paths in JSON with forward slashes (C:/Users/you/Music/Ezkielyna).

Add it to your app

Replace sk-... with your key.

Claude Code

claude mcp add ezkielyna-audio -e EZKIELYNA_API_KEY=sk-... -- npx -y ezkielyna-audio-mcp

Add --scope user to make it available in every project.

Claude Desktop: Settings → Developer → Edit Config (claude_desktop_config.json), then quit and reopen Claude Desktop.

      "args": ["-y", "ezkielyna-audio-mcp"],
      "env": { "EZKIELYNA_API_KEY": "sk-..." }
    }
  }
}

Cursor: ~/.cursor/mcp.json or .cursor/mcp.json, same JSON as Claude Desktop.

OpenCode: opencode.json in the project, or ~/.config/opencode/opencode.json.

Safety and limits

• Reads only audio files with a known extension, up to 25 MB; URLs are refused (local files only). A bare file name is also looked up in the audio folder, so a file text_to_speech just saved can be transcribed again.

• Writes only inside EZKIELYNA_AUDIO_DIR, sanitises file names and never overwrites (name.mp3, name-1.mp3, ...). An answer that is not audio is refused and nothing is saved.

• Text is limited to 4,000 characters per call; transcripts longer than 100,000 characters are truncated.

• The session cap is checked before anything is sent. Calls the gateway clearly refused give their slot back.

• The key is scrubbed from every answer and log line. Logs go to stderr; stdout carries only MCP messages.

Data source

Model list, prices, groups and voice names come at runtime from the public endpoint https://api.ezkielyna.store/api/pricing (no key, cached 10 minutes). Price per 1M units = model_ratio × 2 × lowest group multiplier (New API convention), matching https://api.ezkielyna.store/llms-full.txt (checked 11 Nov 2026). Nothing is bundled. The voice table above was copied from the same price list on 11 Nov 2026; models and voices can change, so list_audio_models is the current source.

FAQ

How can I transcribe an Indonesian voice note with Claude? Add this server, then ask "transcribe ~/Downloads/note.ogg, language id". Claude calls transcribe_audio with whisper-large-v3 and gets the text back.

Is there an Indonesian text-to-speech voice for Claude Desktop or Cursor? Yes. The default edge-tts voice is id-ID-GadisNeural (female); use id-ID-ArdiNeural for a male voice.

Can I make subtitles (SRT/VTT) from a video's audio? Yes, set response_format to srt or vtt. Extract the audio first (for example ffmpeg -i video.mp4 -vn -b:a 64k audio.mp3) if the file is over 25 MB.

Where are the audio files saved? In ~/Music/Ezkielyna unless you set EZKIELYNA_AUDIO_DIR. Existing files are never overwritten.

Is Ezkielyna affiliated with Microsoft, OpenAI or Google? No. Ezkielyna is an independent API gateway and is not affiliated with the model vendors or the MCP client makers.

Development

node --test test/

The tests spawn the server over stdio against a local mock gateway: no internet, no cost.

Bahasa Indonesia

Server MCP agar asisten AI Anda (Claude Desktop, Claude Code, Cursor, OpenCode) bisa mengubah teks jadi suara (disimpan sebagai file MP3/WAV) dan mengubah file audio di komputer jadi teks, termasuk bahasa Indonesia, lewat Ezkielyna API.

Contoh:

• "Transkrip ~/Downloads/vn-pelanggan.ogg (bahasa Indonesia), lalu ringkas jadi 3 poin."

• "Bacakan deskripsi produk ini dengan suara perempuan bahasa Indonesia, simpan sebagai promo-kopi."

Yang dibutuhkan

1. Node.js 18+. Cukup satu file, tanpa npm install.

2. API key Ezkielyna yang grupnya mencakup model audio. Paling mudah: grup Auto. Menurut daftar harga publik (dicek 11 Nov 2026), model suara aktif di grup Standard dan Premium, dan edge-tts juga di Hemat; grup Media (gambar/video) tidak mencantumkannya. Beli API Credit mulai $0.5 lewat QRIS/DANA/GoPay/USDT di ezkielyna.store/beli-api-key, tukarkan di menu Wallet di api.ezkielyna.store, lalu buat key di menu API Keys.

Tool

Contoh harga (daftar harga publik, 11 Nov 2026): edge-tts $1 per 1 juta karakter, jadi 4.000 karakter sekitar $0.004. Biaya pasti ada di Usage Logs dashboard.

Pemasangan

Claude Code:

claude mcp add ezkielyna-audio -e EZKIELYNA_API_KEY=sk-... -- npx -y ezkielyna-audio-mcp

Claude Desktop, Cursor dan OpenCode: pakai contoh JSON di bagian Inggris di atas, cukup ganti sk-.... Di Windows, jika npx tidak jalan, pakai "command": "cmd" dan "args": ["/c", "npx", "-y", "ezkielyna-audio-mcp"].

Keamanan dan batas

• EZKIELYNA_MAX_CALLS (default 30): batas panggilan berbayar per sesi, dicek sebelum permintaan dikirim.

• Hanya membaca file audio (maks 25 MB), bukan link. Hanya menulis di folder audio dan tidak pernah menimpa file yang sudah ada.

• Key tidak pernah ditampilkan di jawaban maupun log.

Tanya jawab

Bagaimana cara transkrip voice note WhatsApp berbahasa Indonesia dengan Claude? Simpan voice note (.ogg/.opus) ke komputer, pasang server ini, lalu minta "transkrip file ini, bahasa id".

Apakah ada suara Indonesia untuk text to speech? Ada: id-ID-GadisNeural (perempuan, default) dan id-ID-ArdiNeural (laki-laki) di edge-tts.

Apakah Ezkielyna berafiliasi dengan Microsoft, OpenAI atau Google? Tidak. Ezkielyna adalah API gateway independen.
