Messaging Platform Integrations (Gateway)

Hermes Agent can connect to messaging platforms like Telegram, Discord, and WhatsApp to serve as a conversational AI assistant.

Quick Start

# 1. Set your bot token(s) in .env file
echo 'TELEGRAM_BOT_TOKEN="your_telegram_bot_token"' >> .env
echo 'DISCORD_BOT_TOKEN="your_discord_bot_token"' >> .env

# 2. Test the gateway (foreground)
./scripts/hermes-gateway run

# 3. Install as a system service (runs in background)
./scripts/hermes-gateway install

# 4. Manage the service
./scripts/hermes-gateway start
./scripts/hermes-gateway stop
./scripts/hermes-gateway restart
./scripts/hermes-gateway status

Quick test (without service install):

python cli.py --gateway  # Runs in foreground, useful for debugging

Session Management

Session Persistence

Sessions persist across messages until they reset. The agent remembers your conversation context.

Reset Policies

Sessions reset based on configurable policies:

Policy	Default	Description
Daily	4:00 AM	Reset at a specific hour each day
Idle	120 min	Reset after N minutes of inactivity
Both	(combined)	Whichever triggers first

Manual Reset

Send /new or /reset as a message to start fresh.

Per-Platform Overrides

Configure different reset policies per platform:

{
  "reset_by_platform": {
    "telegram": { "mode": "idle", "idle_minutes": 240 },
    "discord": { "mode": "idle", "idle_minutes": 60 }
  }
}

Platform Setup

Telegram

1. Create a bot via @BotFather
2. Get your token (looks like 123456789:ABCdefGHIjklMNOpqrsTUVwxyz)
3. Set environment variable:

   export TELEGRAM_BOT_TOKEN="your_token_here"
   

4. Optional: Set home channel for cron job delivery:

   export TELEGRAM_HOME_CHANNEL="-1001234567890"
   export TELEGRAM_HOME_CHANNEL_NAME="My Notes"
   

Requirements:

pip install python-telegram-bot>=20.0

Discord

1. Create an application at Discord Developer Portal
2. Create a bot under your application
3. Get the bot token
4. Enable required intents:
   • Message Content Intent
   • Server Members Intent (optional)
5. Invite to your server using OAuth2 URL generator (scopes: bot, applications.commands)
6. Set environment variable:

   export DISCORD_BOT_TOKEN="your_token_here"
   

7. Optional: Set home channel:

   export DISCORD_HOME_CHANNEL="123456789012345678"
   export DISCORD_HOME_CHANNEL_NAME="#bot-updates"
   

Requirements:

pip install discord.py>=2.0

WhatsApp

WhatsApp uses a built-in bridge powered by Baileys that connects via WhatsApp Web. The agent links to your WhatsApp account and responds to incoming messages.

Setup:

hermes whatsapp

This will:

• Enable WhatsApp in your .env
• Ask for your phone number (for the allowlist)
• Install bridge dependencies (Node.js required)
• Display a QR code — scan it with your phone (WhatsApp → Settings → Linked Devices → Link a Device)
• Exit automatically once paired

Then start the gateway:

hermes gateway

The gateway starts the WhatsApp bridge automatically using the saved session credentials in ~/.hermes/whatsapp/session/.

Environment variables:

WHATSAPP_ENABLED=true
WHATSAPP_ALLOWED_USERS=15551234567    # Comma-separated phone numbers with country code

Agent responses are prefixed with "⚕ Hermes Agent" so you can distinguish them from your own messages when messaging yourself.

Re-pairing: If WhatsApp Web sessions disconnect (protocol updates, phone reset), re-pair with hermes whatsapp.

Configuration

There are three ways to configure the gateway (in order of precedence):

1. Environment Variables (.env file) - Recommended for Quick Setup

Add to your ~/.hermes/.env file:

# =============================================================================
# MESSAGING PLATFORM TOKENS
# =============================================================================

# Telegram - get from @BotFather on Telegram
TELEGRAM_BOT_TOKEN=your_telegram_bot_token
TELEGRAM_ALLOWED_USERS=123456789,987654321    # Security: restrict to these user IDs

# Optional: Default channel for cron job delivery
TELEGRAM_HOME_CHANNEL=-1001234567890
TELEGRAM_HOME_CHANNEL_NAME="My Notes"

# Discord - get from Discord Developer Portal
DISCORD_BOT_TOKEN=your_discord_bot_token
DISCORD_ALLOWED_USERS=123456789012345678      # Security: restrict to these user IDs

# Optional: Default channel for cron job delivery
DISCORD_HOME_CHANNEL=123456789012345678
DISCORD_HOME_CHANNEL_NAME="#bot-updates"

# Slack - get from Slack API (api.slack.com/apps)
SLACK_BOT_TOKEN=xoxb-your-slack-bot-token
SLACK_APP_TOKEN=xapp-your-slack-app-token      # Required for Socket Mode
SLACK_ALLOWED_USERS=U01234ABCDE                # Security: restrict to these user IDs

# Optional: Default channel for cron job delivery
# SLACK_HOME_CHANNEL=C01234567890

# WhatsApp - pair via: hermes whatsapp
WHATSAPP_ENABLED=true
WHATSAPP_ALLOWED_USERS=15551234567             # Phone numbers with country code

# =============================================================================
# AGENT SETTINGS
# =============================================================================

# Max tool-calling iterations per conversation (default: 60)
HERMES_MAX_ITERATIONS=60

# Working directory for terminal commands (default: home ~)
MESSAGING_CWD=/home/myuser

# =============================================================================
# TOOL PROGRESS NOTIFICATIONS
# =============================================================================

# Show progress messages as agent uses tools
HERMES_TOOL_PROGRESS=true

# Mode: "new" (only when tool changes) or "all" (every tool call)
HERMES_TOOL_PROGRESS_MODE=new

# =============================================================================
# SESSION SETTINGS
# =============================================================================

# Reset sessions after N minutes of inactivity (default: 120)
SESSION_IDLE_MINUTES=120

# Daily reset hour in 24h format (default: 4 = 4am)
SESSION_RESET_HOUR=4

2. Gateway Config File (~/.hermes/gateway.json) - Full Control

For advanced configuration, create ~/.hermes/gateway.json:

{
  "platforms": {
    "telegram": {
      "enabled": true,
      "token": "your_telegram_token",
      "home_channel": {
        "platform": "telegram",
        "chat_id": "-1001234567890",
        "name": "My Notes"
      }
    },
    "discord": {
      "enabled": true,
      "token": "your_discord_token",
      "home_channel": {
        "platform": "discord",
        "chat_id": "123456789012345678",
        "name": "#bot-updates"
      }
    }
  },
  "default_reset_policy": {
    "mode": "both",
    "at_hour": 4,
    "idle_minutes": 120
  },
  "reset_by_platform": {
    "discord": {
      "mode": "idle",
      "idle_minutes": 60
    }
  },
  "always_log_local": true
}

Platform-Specific Toolsets

Each platform has its own toolset for security:

Platform	Toolset	Capabilities
CLI	hermes-cli	Full access (terminal, browser, etc.)
Telegram	hermes-telegram	Full tools including terminal
Discord	hermes-discord	Full tools including terminal
WhatsApp	hermes-whatsapp	Full tools including terminal
Slack	hermes-slack	Full tools including terminal

User Experience Features

Typing Indicator

The gateway keeps the "typing..." indicator active throughout processing, refreshing every 4 seconds. This lets users know the bot is working even during long tool-calling sequences.

Tool Progress Notifications

When HERMES_TOOL_PROGRESS=true, the bot sends status messages as it works:

💻 `ls -la`...
🔍 web_search...
📄 web_extract...
🎨 image_generate...

Terminal commands show the actual command (truncated to 50 chars). Other tools just show the tool name.

Modes:

• new: Only sends message when switching to a different tool (less spam)
• all: Sends message for every single tool call

Working Directory

• CLI (hermes command): Uses current directory where you run the command
• Messaging: Uses MESSAGING_CWD (default: home directory ~)

This is intentional: CLI users are in a terminal and expect the agent to work in their current directory, while messaging users need a consistent starting location.

Max Iterations

If the agent hits the max iteration limit while working, instead of a generic error, it asks the model to summarize what it found so far. This gives you a useful response even when the task couldn't be fully completed.

Voice Messages (TTS)

The text_to_speech tool generates audio that the gateway delivers as native voice messages on each platform:

Platform	Delivery	Format
Telegram	Voice bubble (plays inline)	Opus .ogg — native from OpenAI/ElevenLabs, converted via ffmpeg for Edge TTS
Discord	Audio file attachment	MP3
WhatsApp	Audio file attachment	MP3
CLI	Saved to ~/voice-memos/	MP3

Providers:

• Edge TTS (default) — Free, no API key, 322 voices in 74 languages
• ElevenLabs — Premium quality, requires ELEVENLABS_API_KEY
• OpenAI TTS — Good quality, requires OPENAI_API_KEY

Voice and provider are configured by the user in ~/.hermes/config.yaml under the tts: key. The model only sends text; it does not choose the voice.

The tool returns a MEDIA:<path> tag that the gateway send pipeline intercepts and delivers as a native audio message. If [[audio_as_voice]] is present (Opus format available), Telegram sends it as a voice bubble instead of an audio file.

Telegram voice bubbles & ffmpeg:

Telegram requires Opus/OGG format for native voice bubbles (the round, inline-playable kind). OpenAI and ElevenLabs produce Opus natively when on Telegram — no extra setup needed. Edge TTS (the default free provider) outputs MP3 and needs ffmpeg to convert:

sudo apt install ffmpeg    # Ubuntu/Debian
brew install ffmpeg         # macOS
sudo dnf install ffmpeg     # Fedora

Without ffmpeg, Edge TTS audio is sent as a regular audio file (still playable, but shows as a rectangular music player instead of a voice bubble).

Cron Job Delivery

Cron jobs are executed automatically by the gateway daemon. When the gateway is running (via hermes gateway or hermes gateway install), it ticks the scheduler every 60 seconds and runs due jobs.

When scheduling cron jobs, you can specify where the output should be delivered:

User: "Remind me to check the server in 30 minutes"

Agent uses: schedule_cronjob(
  prompt="Check server status...",
  schedule="30m",
  deliver="origin"  # Back to this chat
)

Delivery Options

Option	Description
"origin"	Back to where the job was created
"local"	Save to local files only
"telegram"	Telegram home channel
"discord"	Discord home channel
"telegram:123456"	Specific Telegram chat

Dynamic Context Injection

The agent knows where it is via injected context:

## Current Session Context

**Source:** Telegram (group: Dev Team, ID: -1001234567890)
**Connected Platforms:** local, telegram, discord

**Home Channels:**
  - telegram: My Notes (ID: -1001234567890)
  - discord: #bot-updates (ID: 123456789012345678)

**Delivery options for scheduled tasks:**
- "origin" → Back to this chat (Dev Team)
- "local" → Save to local files only
- "telegram" → Home channel (My Notes)
- "discord" → Home channel (#bot-updates)

CLI Commands

Command	Description
/platforms	Show gateway configuration and status
--gateway	Start the gateway (CLI flag)

Troubleshooting

"python-telegram-bot not installed"

pip install python-telegram-bot>=20.0

"discord.py not installed"

pip install discord.py>=2.0

"No platforms connected"

1. Check your environment variables are set
2. Check your tokens are valid
3. Try /platforms to see configuration status

Session not persisting

1. Check ~/.hermes/sessions/ exists
2. Check session policies aren't too aggressive
3. Verify no errors in gateway logs

Adding a New Platform

To add a new messaging platform:

1. Create the adapter

Create gateway/platforms/your_platform.py:

from gateway.platforms.base import BasePlatformAdapter, MessageEvent, SendResult
from gateway.config import Platform, PlatformConfig

class YourPlatformAdapter(BasePlatformAdapter):
    def __init__(self, config: PlatformConfig):
        super().__init__(config, Platform.YOUR_PLATFORM)
    
    async def connect(self) -> bool:
        # Connect to the platform
        ...
    
    async def disconnect(self) -> None:
        # Disconnect
        ...
    
    async def send(self, chat_id: str, content: str, ...) -> SendResult:
        # Send a message
        ...
    
    async def get_chat_info(self, chat_id: str) -> Dict[str, Any]:
        # Get chat information
        ...

2. Register the platform

Add to gateway/config.py:

class Platform(Enum):
    # ... existing ...
    YOUR_PLATFORM = "your_platform"

3. Add to gateway runner

Update gateway/run.py _create_adapter():

elif platform == Platform.YOUR_PLATFORM:
    from gateway.platforms.your_platform import YourPlatformAdapter
    return YourPlatformAdapter(config)

4. Create a toolset (optional)

Add to toolsets.py:

"hermes-your-platform": {
    "description": "Your platform toolset",
    "tools": [...],
    "includes": []
}

5. Configure

Add environment variables to .env:

YOUR_PLATFORM_TOKEN=...
YOUR_PLATFORM_HOME_CHANNEL=...

Service Management

# Enable lingering (keeps running after logout)
sudo loginctl enable-linger $USER

macOS (launchd)

# Install
./scripts/hermes-gateway install

# Manage
launchctl start ai.hermes.gateway
launchctl stop ai.hermes.gateway

Manual (any platform)

# Run in foreground (for testing/debugging)
./scripts/hermes-gateway run

# Or via CLI (also foreground)
python cli.py --gateway

Interrupting the Agent

Send any message while the agent is working to interrupt it. The message becomes the next prompt after the agent stops. Key behaviors:

• In-progress terminal commands are killed immediately -- SIGTERM first, SIGKILL after 1 second if the process resists. Works on local, Docker, SSH, Singularity, and Modal backends.
• Tool calls are cancelled -- if the model generated multiple tool calls in one batch, only the currently-executing one runs. The rest are skipped.
• Multiple messages are combined -- if you send "Stop!" then "Do X instead" while the agent is stopping, both messages are joined into one prompt (separated by newline).
• /stop command -- interrupts without queuing a follow-up message.
• Priority processing -- interrupt signals bypass command parsing and session creation for minimal latency.
