## Installation

For local development, the CLI uses the actual ConversationalAgent from the parent package:

```bash
# 1. Build the parent package first
cd /path/to/conversational-agent
pnpm install
pnpm build

# 2. The CLI will be built automatically via postinstall hook
# Or build manually:
cd cli
pnpm install
pnpm build
```

## Usage

### Interactive Mode (Recommended)

```bash
# From the parent conversational-agent directory
pnpm cli

# This automatically builds if needed and runs the CLI
```

### With Command Line Arguments

```bash
conversational-agent \
  --account-id=0.0.12345 \
  --private-key=your-private-key \
  --network=testnet \
  --openai-api-key=sk-...
```

### Using Environment Variables

The CLI automatically loads configuration from `.env` in the conversational-agent root:

```bash
# .env file in conversational-agent directory
HEDERA_ACCOUNT_ID=0.0.12345
HEDERA_PRIVATE_KEY=your-private-key
HEDERA_NETWORK=testnet
OPENAI_API_KEY=sk-...
MCP_SERVERS=[{"name":"filesystem","command":"npx","args":["-y","@modelcontextprotocol/server-filesystem","/tmp"]}]
```

Then simply run: `pnpm cli`

## Examples

### Basic Chat Interaction

```
$ Find all AI agents on the network
→ I'll search for AI agents registered on the Hedera network...

[INFO] Found 5 agents with AI capabilities
→ Here are the AI agents I found:
1. Agent: 0.0.12345 - "GPT Assistant"
2. Agent: 0.0.23456 - "Code Helper"
...

$ Connect to agent 0.0.12345

```

### MCP File Operations

With filesystem MCP server enabled:

```
$ Create a new file called notes.txt with my meeting notes
→ I'll create a notes.txt file for you with meeting notes...

[INFO] MCP servers enabled: filesystem
→ I've created notes.txt in your configured directory with the meeting notes.

$ List all files in the current directory
→ Here are the files in /tmp:
- notes.txt (created just now)
- data.json
- config.yaml
```

### Custom MCP Server

```
$ Add GitHub repository operations
→ I can help you interact with GitHub repositories...

[INFO] MCP servers enabled: filesystem, github
