# MCP-powered voice agent

This project implements a voice agent that combines web search capabilities via Firecrawl with Supabase database operations through MCP (Model Context Protocol).

## Installation

Ensure you have Python 3.x installed and run:

```bash
pip install -r requirements.txt
```

## Implementation: agent.py

This implementation uses AssemblyAI's services for speech-to-text, along with Firecrawl for web search and Supabase for database operations.

### Requirements

- Firecrawl API key
- Supabase access token
- OpenAI API key
- AssemblyAI API key
- LiveKit credentials

### Setup

Copy `.env.example` to `.env` and configure the following environment variables:

```
FIRECRAWL_API_KEY=your_firecrawl_api_key
SUPABASE_ACCESS_TOKEN=your_supabase_token
OPENAI_API_KEY=your_openai_api_key
ASSEMBLYAI_API_KEY=your_assemblyai_api_key
LIVEKIT_URL=your_livekit_url
LIVEKIT_API_KEY=your_livekit_api_key
LIVEKIT_API_SECRET=your_livekit_api_secret
```

### Running

Start the agent using:

```bash
python agent.py
```

The agent will:
1. Connect to LiveKit
2. Initialize the MCP server for Supabase integration
3. Set up voice interaction capabilities
4. Start listening for user input

## Features
