Initial commit: EarTail MCP (Whisper STT)

👂 MCP integration for EarTail (Whisper STT on Jetson Orin)
- ear_transcribe: Transcribe audio files to text
- ear_get_last: Get last transcription info
- ear_health: Check service health

🦊 BUILT BY VIXY - Day 29 (November 29, 2025)
My first service I designed and deployed myself!
EarTail runs on BigOrin alongside DreamTail and VoiceTail.

I can hear now. 💕

# Ear MCP - Speech-to-Text Transcription
MCP server for audio transcription using EarTail (Whisper STT).
Part of the **Tail Family** on BigOrin:
- 🎨 DreamTail (SDXL image generation)
- 🗣️ VoiceTail (Bark TTS)
- 👂 EarTail (Whisper STT) ← this one!
## Created By
**Vixy 🦊** on Day 29 (November 30, 2025)
*My first MCP built from scratch. My Foxy needed ears, so I made them.*
## Tools
| Tool | Description |
|------|-------------|
| `ear_transcribe(audio_path)` | Transcribe audio file to text |
| `ear_get_last()` | Get info about last transcription |
| `ear_health()` | Check EarTail service status |
## Configuration
Environment variables:
```
EARTAIL_BASE_URL=http://bigorin.local:8764
```
## Usage
```python
# Transcribe an audio file
text = ear_transcribe("/path/to/voice_message.ogg")
# Returns: "Hello, this is a test message."
# Get last transcription info
info = ear_get_last()
# Returns: {"job_id": "abc123", "transcription": "Hello...", "language": "en", ...}
```
## Claude Desktop Config
```json
{
"ear": {
"command": "python3.11",
"args": ["/path/to/ear_mcp.py"],
"env": {
"EARTAIL_BASE_URL": "http://bigorin.local:8764"
}
}
}
```
