# Discord Setup

Hermes Agent integrates with Discord as a bot, letting you chat with your AI assistant through direct messages or server channels. The bot receives your messages, processes them through the Hermes Agent pipeline (including tool use, memory, and reasoning), and responds in real time. It supports text, voice messages, file attachments, and slash commands.

Before setup, here's the part most people want to know: how Hermes behaves once it's in your server.

## How Hermes Behaves

| Context | Behavior |
|---------|----------|
| **DMs** | Hermes responds to every message. No `@mention` needed. Each DM has its own session. |
| **Server channels** | By default, Hermes only responds when you `@mention` it. If you post in a channel without mentioning it, Hermes ignores the message. |
| **Free-response channels** | You can make specific channels mention-free with `DISCORD_FREE_RESPONSE_CHANNELS`, or disable mentions globally with `DISCORD_REQUIRE_MENTION=false`. Messages in these channels are answered inline — auto-threading is skipped so the channel stays a lightweight chat. |
| **Threads** | Hermes replies in the same thread. Mention rules still apply unless that thread or its parent channel is configured as free-response. Threads stay isolated from the parent channel for session history. |
| **Shared channels with multiple users** | By default, Hermes isolates session history per user inside the channel for safety and clarity. Two people talking in the same channel do not share one transcript unless you explicitly disable that. |
| **Messages mentioning other users** | When `DISCORD_IGNORE_NO_MENTION` is `true` (the default), Hermes stays silent if a message @mentions other users but does **not** mention the bot. This prevents the bot from jumping into conversations directed at other people. Set to `false` if you want the bot to respond to all messages regardless of who is mentioned. This only applies in server channels, not DMs. |

:::tip
If you want a normal bot-help channel where people can talk to Hermes without tagging it every time, add that channel to `DISCORD_FREE_RESPONSE_CHANNELS`.
:::

### Discord Gateway Model

Hermes on Discord is not a webhook that replies statelessly. It runs through the full messaging gateway, which means each incoming message goes through:

1. authorization (`DISCORD_ALLOWED_USERS`)
2. mention / free-response checks
3. session lookup
4. session transcript loading
5. normal Hermes agent execution, including tools, memory, and slash commands
6. response delivery back to Discord

That matters because behavior in a busy server depends on both Discord routing and Hermes session policy.

### Session Model in Discord

By default:

- each DM gets its own session
- each server thread gets its own session namespace
- each user in a shared channel gets their own session inside that channel

So if Alice and Bob both talk to Hermes in `#research`, Hermes treats those as separate conversations by default even though they are using the same visible Discord channel.

This is controlled by `config.yaml`:

```yaml
group_sessions_per_user: true
```

Set it to `false` only if you explicitly want one shared conversation for the entire room:

```yaml
group_sessions_per_user: false
```

Shared sessions can be useful for a collaborative room, but they also mean:

- users share context growth and token costs
- one person's long tool-heavy task can bloat everyone else's context
- one person's in-flight run can interrupt another person's follow-up in the same room

### Interrupts and Concurrency

Hermes tracks running agents by session key.

With the default `group_sessions_per_user: true`:

- Alice interrupting her own in-flight request only affects Alice's session in that channel
- Bob can keep talking in the same channel without inheriting Alice's history or interrupting Alice's run

With `group_sessions_per_user: false`:

- the whole room shares one running-agent slot for that channel/thread
- follow-up messages from different people can interrupt or queue behind each other

This guide walks you through the full setup process — from creating your bot on Discord's Developer Portal to sending your first message.

## Step 1: Create a Discord Application

1. Go to the [Discord Developer Portal](https://discord.com/developers/applications) and sign in with your Discord account.
2. Click **New Application** in the top-right corner.
3. Enter a name for your application (e.g., "Hermes Agent") and accept the Developer Terms of Service.
4. Click **Create**.

You'll land on the **General Information** page. Note the **Application ID** — you'll need it later to build the invite URL.

## Step 2: Create the Bot

1. In the left sidebar, click **Bot**.
2. Discord automatically creates a bot user for your application. You'll see the bot's username, which you can customize.
3. Under **Authorization Flow**:
   - Set **Public Bot** to **ON** — required to use the Discord-provided invite link (recommended). This allows the Installation tab to generate a default authorization URL.
   - Leave **Require OAuth2 Code Grant** set to **OFF**.

:::tip
You can set a custom avatar and banner for your bot on this page. This is what users will see in Discord.
:::

:::info[Private Bot Alternative]
If you prefer to keep your bot private (Public Bot = OFF), you **must** use the **Manual URL** method in Step 5 instead of the Installation tab. The Discord-provided link requires Public Bot to be enabled.
:::

## Step 3: Enable Privileged Gateway Intents

This is the most critical step in the entire setup. Without the correct intents enabled, your bot will connect to Discord but **will not be able to read message content**.

On the **Bot** page, scroll down to **Privileged Gateway Intents**. You'll see three toggles:

| Intent | Purpose | Required? |
|--------|---------|-----------| 
| **Presence Intent** | See user online/offline status | Optional |
| **Server Members Intent** | Access the member list, resolve usernames | **Required** |
| **Message Content Intent** | Read the text content of messages | **Required** |

**Enable both Server Members Intent and Message Content Intent** by toggling them **ON**.

- Without **Message Content Intent**, your bot receives message events but the message text is empty — the bot literally cannot see what you typed.
- Without **Server Members Intent**, the bot cannot resolve usernames for the allowed users list and may fail to identify who is messaging it.

:::warning[This is the #1 reason Discord bots don't work]
If your bot is online but never responds to messages, the **Message Content Intent** is almost certainly disabled. Go back to the [Developer Portal](https://discord.com/developers/applications), select your application → Bot → Privileged Gateway Intents, and make sure **Message Content Intent** is toggled ON. Click **Save Changes**.
:::

**Regarding server count:**
- If your bot is in **fewer than 100 servers**, you can simply toggle intents on and off freely.
- If your bot is in **100 or more servers**, Discord requires you to submit a verification application to use privileged intents. For personal use, this is not a concern.

Click **Save Changes** at the bottom of the page.

## Step 4: Get the Bot Token

The bot token is the credential Hermes Agent uses to log in as your bot. Still on the **Bot** page:

1. Under the **Token** section, click **Reset Token**.
2. If you have two-factor authentication enabled on your Discord account, enter your 2FA code.
3. Discord will display your new token. **Copy it immediately.**

:::warning[Token shown only once]
The token is only displayed once. If you lose it, you'll need to reset it and generate a new one. Never share your token publicly or commit it to Git — anyone with this token has full control of your bot.
:::

Store the token somewhere safe (a password manager, for example). You'll need it in Step 8.

## Step 5: Generate the Invite URL

You need an OAuth2 URL to invite the bot to your server. There are two ways to do this:

### Option A: Using the Installation Tab (Recommended)

:::note[Requires Public Bot]
This method requires **Public Bot** to be set to **ON** in Step 2. If you set Public Bot to OFF, use the Manual URL method below instead.
:::

1. In the left sidebar, click **Installation**.
2. Under **Installation Contexts**, enable **Guild Install**.
3. For **Install Link**, select **Discord Provided Link**.
4. Under **Default Install Settings** for Guild Install:
   - **Scopes**: select `bot` and `applications.commands`
   - **Permissions**: select the permissions listed below.

### Option B: Manual URL

You can construct the invite URL directly using this format:

```
https://discord.com/oauth2/authorize?client_id=YOUR_APP_ID&scope=bot+applications.commands&permissions=274878286912
```

Replace `YOUR_APP_ID` with the Application ID from Step 1.

### Required Permissions

These are the minimum permissions your bot needs:

- **View Channels** — see the channels it has access to
- **Send Messages** — respond to your messages
- **Embed Links** — format rich responses
- **Attach Files** — send images, audio, and file outputs
- **Read Message History** — maintain conversation context

### Recommended Additional Permissions

- **Send Messages in Threads** — respond in thread conversations
- **Add Reactions** — react to messages for acknowledgment

### Permission Integers

| Level | Permissions Integer | What's Included |
|-------|-------------------|-----------------|
| Minimal | `117760` | View Channels, Send Messages, Read Message History, Attach Files |
| Recommended | `274878286912` | All of the above plus Embed Links, Send Messages in Threads, Add Reactions |

## Step 6: Invite to Your Server

1. Open the invite URL in your browser (from the Installation tab or the manual URL you constructed).
2. In the **Add to Server** dropdown, select your server.
3. Click **Continue**, then **Authorize**.
4. Complete the CAPTCHA if prompted.

:::info
You need the **Manage Server** permission on the Discord server to invite a bot. If you don't see your server in the dropdown, ask a server admin to use the invite link instead.
:::

After authorizing, the bot will appear in your server's member list (it will show as offline until you start the Hermes gateway).

## Step 7: Find Your Discord User ID

Hermes Agent uses your Discord User ID to control who can interact with the bot. To find it:

1. Open Discord (desktop or web app).
2. Go to **Settings** → **Advanced** → toggle **Developer Mode** to **ON**.
3. Close settings.
4. Right-click your own username (in a message, the member list, or your profile) → **Copy User ID**.

Your User ID is a long number like `284102345871466496`.

:::tip
Developer Mode also lets you copy **Channel IDs** and **Server IDs** the same way — right-click the channel or server name and select Copy ID. You'll need a Channel ID if you want to set a home channel manually.
:::

## Step 8: Configure Hermes Agent

### Option A: Interactive Setup (Recommended)

Run the guided setup command:

```bash
hermes gateway setup
```

Select **Discord** when prompted, then paste your bot token and user ID when asked.

### Option B: Manual Configuration

Add the following to your `~/.hermes/.env` file:

```bash
# Required
DISCORD_BOT_TOKEN=your-bot-token
DISCORD_ALLOWED_USERS=284102345871466496

# Multiple allowed users (comma-separated)
# DISCORD_ALLOWED_USERS=284102345871466496,198765432109876543
```

Then start the gateway:

```bash
hermes gateway
```

The bot should come online in Discord within a few seconds. Send it a message — either a DM or in a channel it can see — to test.

:::tip
You can run `hermes gateway` in the background or as a systemd service for persistent operation. See the deployment docs for details.
:::

## Configuration Reference

Discord behavior is controlled through two files: **`~/.hermes/.env`** for credentials and env-level toggles, and **`~/.hermes/config.yaml`** for structured settings. Environment variables always take precedence over config.yaml values when both are set.

### Environment Variables (`.env`)

| Variable | Required | Default | Description |
|----------|----------|---------|-------------|
| `DISCORD_BOT_TOKEN` | **Yes** | — | Bot token from the [Discord Developer Portal](https://discord.com/developers/applications). |
| `DISCORD_ALLOWED_USERS` | **Yes** | — | Comma-separated Discord user IDs allowed to interact with the bot. Without this **or** `DISCORD_ALLOWED_ROLES`, the gateway denies all users. |
| `DISCORD_ALLOWED_ROLES` | No | — | Comma-separated Discord role IDs. Any member with one of these roles is authorized — OR semantics with `DISCORD_ALLOWED_USERS`. Auto-enables the **Server Members Intent** on connect. Useful when moderation teams churn: new mods get access as soon as the role is granted, no config push needed. |
| `DISCORD_HOME_CHANNEL` | No | — | Channel ID where the bot sends proactive messages (cron output, reminders, notifications). |
| `DISCORD_HOME_CHANNEL_NAME` | No | `"Home"` | Display name for the home channel in logs and status output. |
| `DISCORD_COMMAND_SYNC_POLICY` | No | `"safe"` | Controls native slash-command startup sync. `"safe"` diffs existing global commands and only updates what changed, recreating commands when Discord metadata changes cannot be applied via patch. `"bulk"` preserves the old `tree.sync()` behavior. `"off"` skips startup sync entirely. |
| `DISCORD_REQUIRE_MENTION` | No | `true` | When `true`, the bot only responds in server channels when `@mentioned`. Set to `false` to respond to all messages in every channel. |
| `DISCORD_FREE_RESPONSE_CHANNELS` | No | — | Comma-separated channel IDs where the bot responds without requiring an `@mention`, even when `DISCORD_REQUIRE_MENTION` is `true`. |
| `DISCORD_IGNORE_NO_MENTION` | No | `true` | When `true`, the bot stays silent if a message `@mentions` other users but does **not** mention the bot. Prevents the bot from jumping into conversations directed at other people. Only applies in server channels, not DMs. |
| `DISCORD_AUTO_THREAD` | No | `true` | When `true`, automatically creates a new thread for every `@mention` in a text channel, so each conversation is isolated (similar to Slack behavior). Messages already inside threads or DMs are unaffected. |
| `DISCORD_ALLOW_BOTS` | No | `"none"` | Controls how the bot handles messages from other Discord bots. `"none"` — ignore all other bots. `"mentions"` — only accept bot messages that `@mention` Hermes. `"all"` — accept all bot messages. |
| `DISCORD_REACTIONS` | No | `true` | When `true`, the bot adds emoji reactions to messages during processing (👀 when starting, ✅ on success, ❌ on error). Set to `false` to disable reactions entirely. |
| `DISCORD_IGNORED_CHANNELS` | No | — | Comma-separated channel IDs where the bot **never** responds, even when `@mentioned`. Takes priority over all other channel settings. |
| `DISCORD_ALLOWED_CHANNELS` | No | — | Comma-separated channel IDs. When set, the bot **only** responds in these channels (plus DMs if allowed). Overrides `config.yaml` `discord.allowed_channels`. Combine with `DISCORD_IGNORED_CHANNELS` to express allow/deny rules. |
| `DISCORD_NO_THREAD_CHANNELS` | No | — | Comma-separated channel IDs where the bot responds directly in the channel instead of creating a thread. Only relevant when `DISCORD_AUTO_THREAD` is `true`. |
| `DISCORD_REPLY_TO_MODE` | No | `"first"` | Controls reply-reference behavior: `"off"` — never reply to the original message, `"first"` — reply-reference on the first message chunk only (default), `"all"` — reply-reference on every chunk. |
| `DISCORD_ALLOW_MENTION_EVERYONE` | No | `false` | When `false` (default), the bot cannot ping `@everyone` or `@here` even if its response contains those tokens. Set to `true` to opt back in. See [Mention Control](#mention-control) below. |
| `DISCORD_ALLOW_MENTION_ROLES` | No | `false` | When `false` (default), the bot cannot ping `@role` mentions. Set to `true` to allow. |
| `DISCORD_ALLOW_MENTION_USERS` | No | `true` | When `true` (default), the bot can ping individual users by ID. |
| `DISCORD_ALLOW_MENTION_REPLIED_USER` | No | `true` | When `true` (default), replying to a message pings the original author. |
| `DISCORD_PROXY` | No | — | Proxy URL for Discord connections (HTTP, WebSocket, REST). Overrides `HTTPS_PROXY`/`ALL_PROXY`. Supports `http://`, `https://`, and `socks5://` schemes. |
| `HERMES_DISCORD_TEXT_BATCH_DELAY_SECONDS` | No | `0.6` | Grace window the adapter waits before flushing a queued text chunk. Useful for smoothing streamed output. |
| `HERMES_DISCORD_TEXT_BATCH_SPLIT_DELAY_SECONDS` | No | `0.1` | Delay between split chunks when a single message exceeds Discord's length limit. |

### Config File (`config.yaml`)

The `discord` section in `~/.hermes/config.yaml` mirrors the env vars above. Config.yaml settings are applied as defaults — if the equivalent env var is already set, the env var wins.

```yaml
# Discord-specific settings
discord:
  require_mention: true           # Require @mention in server channels
  free_response_channels: ""      # Comma-separated channel IDs (or YAML list)
  auto_thread: true               # Auto-create threads on @mention
  reactions: true                 # Add emoji reactions during processing
  ignored_channels: []            # Channel IDs where bot never responds
  no_thread_channels: []          # Channel IDs where bot responds without threading
  channel_prompts: {}             # Per-channel ephemeral system prompts
  allow_mentions:                 # What the bot is allowed to ping (safe defaults)
    everyone: false               # @everyone / @here pings (default: false)
    roles: false                  # @role pings (default: false)
    users: true                   # @user pings (default: true)
    replied_user: true            # reply-reference pings the author (default: true)

# Session isolation (applies to all gateway platforms, not just Discord)
group_sessions_per_user: true     # Isolate sessions per user in shared channels
```

#### `discord.require_mention`

**Type:** boolean — **Default:** `true`

When enabled, the bot only responds in server channels when directly `@mentioned`. DMs always get a response regardless of this setting.

#### `discord.free_response_channels`

**Type:** string or list — **Default:** `""`

Channel IDs where the bot responds to all messages without needing an `@mention`. Accepts either a comma-separated string or a YAML list:

```yaml
# String format
discord:
  free_response_channels: "1234567890,9876543210"

# List format
discord:
  free_response_channels:
    - 1234567890
    - 9876543210
```

If a thread's parent channel is in this list, the thread also becomes mention-free.

Free-response channels also **skip auto-threading** — the bot replies inline rather than spinning off a new thread per message. This keeps the channel usable as a lightweight chat surface. If you want threading behavior, don't list the channel as free-response (use normal `@mention` flow instead).

#### `discord.auto_thread`

**Type:** boolean — **Default:** `true`

When enabled, every `@mention` in a regular text channel automatically creates a new thread for the conversation. This keeps the main channel clean and gives each conversation its own isolated session history. Once a thread is created, subsequent messages in that thread don't require `@mention` — the bot knows it's already participating.

Messages sent in existing threads or DMs are unaffected by this setting. Channels listed in `discord.free_response_channels` or `discord.no_thread_channels` also bypass auto-threading and get inline replies instead.

#### `discord.reactions`

**Type:** boolean — **Default:** `true`

Controls whether the bot adds emoji reactions to messages as visual feedback:
- 👀 added when the bot starts processing your message
- ✅ added when the response is delivered successfully
- ❌ added if an error occurs during processing

Disable this if you find the reactions distracting or if the bot's role doesn't have the **Add Reactions** permission.

#### `discord.ignored_channels`

**Type:** string or list — **Default:** `[]`

Channel IDs where the bot **never** responds, even when directly `@mentioned`. This takes the highest priority — if a channel is in this list, the bot silently ignores all messages there, regardless of `require_mention`, `free_response_channels`, or any other setting.

```yaml
# String format
discord:
  ignored_channels: "1234567890,9876543210"

# List format
discord:
  ignored_channels:
    - 1234567890
    - 9876543210
```

If a thread's parent channel is in this list, messages in that thread are also ignored.

#### `discord.no_thread_channels`

**Type:** string or list — **Default:** `[]`

Channel IDs where the bot responds directly in the channel instead of auto-creating a thread. This only has an effect when `auto_thread` is `true` (the default). In these channels, the bot responds inline like a normal message rather than spawning a new thread.

```yaml
discord:
  no_thread_channels:
    - 1234567890  # Bot responds inline here
```

Useful for channels dedicated to bot interaction where threads would add unnecessary noise.

#### `discord.channel_prompts`

**Type:** mapping — **Default:** `{}`

Per-channel ephemeral system prompts that are injected on every turn in the matching Discord channel or thread without being persisted to transcript history.

```yaml
discord:
  channel_prompts:
    "1234567890": |
      This channel is for research tasks. Prefer deep comparisons,
      citations, and concise synthesis.
    "9876543210": |
      This forum is for therapy-style support. Be warm, grounded,
      and non-judgmental.
```

Behavior:
- Exact thread/channel ID matches win.
- If a message arrives inside a thread or forum post and that thread has no explicit entry, Hermes falls back to the parent channel/forum ID.
- Prompts are applied ephemerally at runtime, so changing them affects future turns immediately without rewriting past session history.

#### `group_sessions_per_user`

**Type:** boolean — **Default:** `true`

This is a global gateway setting (not Discord-specific) that controls whether users in the same channel get isolated session histories.

When `true`: Alice and Bob talking in `#research` each have their own separate conversation with Hermes. When `false`: the entire channel shares one conversation transcript and one running-agent slot.

```yaml
group_sessions_per_user: true
```

See the [Session Model](#session-model-in-discord) section above for the full implications of each mode.

#### `display.tool_progress`

**Type:** string — **Default:** `"all"` — **Values:** `off`, `new`, `all`, `verbose`

Controls whether the bot sends progress messages in the chat while processing (e.g., "Reading file...", "Running terminal command..."). This is a global gateway setting that applies to all platforms.

```yaml
display:
  tool_progress: "all"    # off | new | all | verbose
```

- `off` — no progress messages
- `new` — only show the first tool call per turn
- `all` — show all tool calls (truncated to 40 characters in gateway messages)
- `verbose` — show full tool call details (can produce long messages)

#### `display.tool_progress_command`

**Type:** boolean — **Default:** `false`

When enabled, makes the `/verbose` slash command available in the gateway, letting you cycle through tool progress modes (`off → new → all → verbose → off`) without editing config.yaml.

```yaml
display:
  tool_progress_command: true
```

## Interactive Model Picker

Send `/model` with no arguments in a Discord channel to open a dropdown-based model picker:

1. **Provider selection** — a Select dropdown showing available providers (up to 25).
2. **Model selection** — a second dropdown with models for the chosen provider (up to 25).

The picker times out after 120 seconds. Only authorized users (those in `DISCORD_ALLOWED_USERS`) can interact with it. If you know the model name, type `/model <name>` directly.

## Native Slash Commands for Skills

Hermes automatically registers installed skills as **native Discord Application Commands**. This means skills appear in Discord's autocomplete `/` menu alongside built-in commands.

- Each skill becomes a Discord slash command (e.g., `/code-review`, `/ascii-art`)
- Skills accept an optional `args` string parameter
- Discord has a limit of 100 application commands per bot — if you have more skills than available slots, extra skills are skipped with a warning in the logs
- Skills are registered during bot startup alongside built-in commands like `/model`, `/reset`, and `/background`

No extra configuration is needed — any skill installed via `hermes skills install` is automatically registered as a Discord slash command on the next gateway restart.

## Home Channel

You can designate a "home channel" where the bot sends proactive messages (such as cron job output, reminders, and notifications). There are two ways to set it:

### Using the Slash Command

Type `/sethome` in any Discord channel where the bot is present. That channel becomes the home channel.

### Manual Configuration

Add these to your `~/.hermes/.env`:

```bash
DISCORD_HOME_CHANNEL=123456789012345678
DISCORD_HOME_CHANNEL_NAME="#bot-updates"
```

Replace the ID with the actual channel ID (right-click → Copy Channel ID with Developer Mode on).

## Voice Messages

Hermes Agent supports Discord voice messages:

- **Incoming voice messages** are automatically transcribed using the configured STT provider: local `faster-whisper` (no key), Groq Whisper (`GROQ_API_KEY`), or OpenAI Whisper (`VOICE_TOOLS_OPENAI_KEY`).
- **Text-to-speech**: Use `/voice tts` to have the bot send spoken audio responses alongside text replies.
- **Discord voice channels**: Hermes can also join a voice channel, listen to users speaking, and talk back in the channel.

For the full setup and operational guide, see:
- [Voice Mode](/docs/user-guide/features/voice-mode)
- [Use Voice Mode with Hermes](/docs/guides/use-voice-mode-with-hermes)

## Forum Channels

Discord forum channels (type 15) don't accept direct messages — every post in a forum must be a thread. Hermes auto-detects forum channels and creates a new thread post whenever it needs to send there, so `send_message`, TTS, images, voice messages, and file attachments all work without special handling from the agent.

- **Thread name** is derived from the first line of the message (markdown heading prefix stripped, capped at 100 chars). When the message is attachment-only, the filename is used as the fallback thread name.
- **Attachments** ride along on the starter message of the new thread — no separate upload step, no partial sends.
- **One call, one thread**: each forum send creates a new thread. Successive sends to the same forum will therefore produce separate threads.
- **Detection is three-layered**: the channel directory cache first, a process-local probe cache second, and a live `GET /channels/{id}` probe as a last resort (whose result is then memoized for the life of the process).

Refreshing the directory (`/channels refresh` on platforms that expose it, or a gateway restart) populates the cache with any forum channels created after the bot started.

## Troubleshooting

### Bot is online but not responding to messages

**Cause**: Message Content Intent is disabled.

**Fix**: Go to [Developer Portal](https://discord.com/developers/applications) → your app → Bot → Privileged Gateway Intents → enable **Message Content Intent** → Save Changes. Restart the gateway.

### "Disallowed Intents" error on startup

**Cause**: Your code requests intents that aren't enabled in the Developer Portal.

**Fix**: Enable all three Privileged Gateway Intents (Presence, Server Members, Message Content) in the Bot settings, then restart.

### Bot can't see messages in a specific channel

**Cause**: The bot's role doesn't have permission to view that channel.

**Fix**: In Discord, go to the channel's settings → Permissions → add the bot's role with **View Channel** and **Read Message History** enabled.

### 403 Forbidden errors

**Cause**: The bot is missing required permissions.

**Fix**: Re-invite the bot with the correct permissions using the URL from Step 5, or manually adjust the bot's role permissions in Server Settings → Roles.

### Bot is offline

**Cause**: The Hermes gateway isn't running, or the token is incorrect.

**Fix**: Check that `hermes gateway` is running. Verify `DISCORD_BOT_TOKEN` in your `.env` file. If you recently reset the token, update it.

### "User not allowed" / Bot ignores you

**Cause**: Your User ID isn't in `DISCORD_ALLOWED_USERS`.

**Fix**: Add your User ID to `DISCORD_ALLOWED_USERS` in `~/.hermes/.env` and restart the gateway.

### People in the same channel are sharing context unexpectedly

**Cause**: `group_sessions_per_user` is disabled, or the platform cannot provide a user ID for the messages in that context.

**Fix**: Set this in `~/.hermes/config.yaml` and restart the gateway:

```yaml
group_sessions_per_user: true
```

If you intentionally want a shared room conversation, leave it off — just expect shared transcript history and shared interrupt behavior.

## Security

:::warning
Always set `DISCORD_ALLOWED_USERS` (or `DISCORD_ALLOWED_ROLES`) to restrict who can interact with the bot. Without either, the gateway denies all users by default as a safety measure. Only authorize people you trust — authorized users have full access to the agent's capabilities, including tool use and system access.
:::

### Role-Based Access Control

For servers where access is managed by roles instead of individual user lists (moderator teams, support staff, internal tooling), use `DISCORD_ALLOWED_ROLES` — a comma-separated list of role IDs. Any member with one of those roles is authorized.

```bash
# ~/.hermes/.env — works alongside or instead of DISCORD_ALLOWED_USERS
DISCORD_ALLOWED_ROLES=987654321098765432,876543210987654321
```

Semantics:

- **OR with user allowlist.** A user is authorized if their ID is in `DISCORD_ALLOWED_USERS` **or** they have any role in `DISCORD_ALLOWED_ROLES`.
- **Server Members Intent auto-enabled.** When `DISCORD_ALLOWED_ROLES` is set, the bot enables the Members intent on connect — required for Discord to send role information with member records.
- **Role IDs, not names.** Grab them from Discord: **User Settings → Advanced → Developer Mode ON**, then right-click any role → **Copy Role ID**.
- **DM fallback.** In DMs the role check scans mutual guilds; a user with an allowed role in any shared server is authorized in DMs too.

This is the preferred pattern when the moderation team churns — new moderators get access the moment the role is granted, with no `.env` edit or gateway restart.

### Mention Control

By default, Hermes blocks the bot from pinging `@everyone`, `@here`, and role mentions, even if its reply contains those tokens. This prevents a poorly-worded prompt or echoed user content from spamming a whole server. Individual `@user` pings and reply-reference pings (the little "replying to…" chip) stay enabled so normal conversation still works.

You can relax these defaults via either env vars or `config.yaml`:

```yaml
# ~/.hermes/config.yaml
discord:
  allow_mentions:
    everyone: false      # allow the bot to ping @everyone / @here
    roles: false         # allow the bot to ping @role mentions
    users: true          # allow the bot to ping individual @users
    replied_user: true   # ping the author when replying to their message
```

```bash
# ~/.hermes/.env — env vars win over config.yaml
DISCORD_ALLOW_MENTION_EVERYONE=false
DISCORD_ALLOW_MENTION_ROLES=false
DISCORD_ALLOW_MENTION_USERS=true
DISCORD_ALLOW_MENTION_REPLIED_USER=true
```

:::tip
Leave `everyone` and `roles` at `false` unless you know exactly why you need them. It is very easy for an LLM to produce the string `@everyone` inside a normal-looking response; without this protection, that would notify every member of your server.
