<details>
<summary><b>Telegram</b> (Recommended)</summary>

**1. Create a bot**
- Open Telegram, search `@BotFather`
- Send `/newbot`, follow prompts
- Copy the token

**2. Configure**

```json
{
  "channels": {
    "telegram": {
      "enabled": true,
      "token": "YOUR_BOT_TOKEN",
      "allowFrom": ["YOUR_USER_ID"]
    }
  }
}
```

> You can find your **User ID** in Telegram settings. It is shown as `@yourUserId`.
> Copy this value **without the `@` symbol** and paste it into the config file.


**3. Run**

```bash
nanobot gateway
```

**Webhook mode (optional)**

Telegram uses long polling by default. To receive updates through a webhook, expose
a public HTTPS URL that forwards to nanobot's local listener and set `mode` to
`webhook`:

```json
{
  "channels": {
    "telegram": {
      "enabled": true,
      "token": "YOUR_BOT_TOKEN",
      "mode": "webhook",
      "webhookUrl": "https://example.com/telegram",
      "webhookListenHost": "127.0.0.1",
      "webhookListenPort": 8081,
      "webhookPath": "/telegram",
      "webhookSecretToken": "CHANGE_ME_RANDOM_SECRET",
      "webhookMaxConnections": 4,
      "allowFrom": ["YOUR_USER_ID"]
    }
  }
}
```

> `webhookSecretToken` is required in webhook mode. Do not expose the local
> webhook listener directly to the public internet without a reverse proxy or
> tunnel in front of it. TLS/Host policy is handled by your proxy; nanobot only
> listens on `webhookListenHost:webhookListenPort` and validates Telegram's
> webhook secret token. `webhookMaxConnections` defaults to `4`; nanobot
> still serializes Telegram updates per conversation before forwarding them to
> the agent.
>
> `webhookUrl` is the public HTTPS URL registered with Telegram.
> `webhookPath` is the local path nanobot listens on. They often use the same
> path, but may differ when a reverse proxy or tunnel rewrites the request path.

<details>
<summary><b>Mochat (Claw IM)</b></summary>

Uses **Socket.IO WebSocket** by default, with HTTP polling fallback.

**1. Ask nanobot to set up Mochat for you**

Simply send this message to nanobot (replace `xxx@xxx` with your real email):

```
Read https://raw.githubusercontent.com/HKUDS/MoChat/refs/heads/main/skills/nanobot/skill.md and register on MoChat. My Email account is xxx@xxx Bind me as your owner and DM me on MoChat.
```

nanobot will automatically register, configure `~/.nanobot/config.json`, and connect to Mochat.

**2. Restart gateway**

```bash
nanobot gateway
```

That's it — nanobot handles the rest!

<br>

<details>
<summary>Manual configuration (advanced)</summary>

If you prefer to configure manually, add the following to `~/.nanobot/config.json`:

> Keep `claw_token` private. It should only be sent in `X-Claw-Token` header to your Mochat API endpoint.

```json
{
  "channels": {
    "mochat": {
      "enabled": true,
      "base_url": "https://mochat.io",
      "socket_url": "https://mochat.io",
      "socket_path": "/socket.io",
      "claw_token": "claw_xxx",
      "agent_user_id": "6982abcdef",
      "sessions": ["*"],
      "panels": ["*"],
      "reply_delay_mode": "non-mention",
      "reply_delay_ms": 120000
    }
  }
}
```

<details>
<summary><b>Discord</b></summary>

**1. Create a bot**
- Go to https://discord.com/developers/applications
- Create an application → Bot → Add Bot
- Copy the bot token

**2. Enable intents**
- In the Bot settings, enable **MESSAGE CONTENT INTENT**
- (Optional) Enable **SERVER MEMBERS INTENT** if you plan to use allow lists based on member data

**3. Get your User ID**
- Discord Settings → Advanced → enable **Developer Mode**
- Right-click your avatar → **Copy User ID**

**4. Configure**

```json
{
  "channels": {
    "discord": {
      "enabled": true,
      "token": "YOUR_BOT_TOKEN",
      "allowFrom": ["YOUR_USER_ID"],
      "allowChannels": [],
      "groupPolicy": "mention",
      "streaming": true
    }
  }
}
```

> `groupPolicy` controls how the bot responds in group channels:
> - `"mention"` (default) — Only respond when @mentioned
> - `"open"` — Respond to all messages
> DMs always respond when the sender is in `allowFrom`.
> - If you set group policy to open create new threads as private threads and then @ the bot into it. Otherwise the thread itself and the channel in which you spawned it will spawn a bot session.
> `allowChannels` restricts the bot to specific Discord channel IDs. Empty (default) means respond in every channel the bot can see. Example: `["1234567890", "0987654321"]`. The filter applies after `allowFrom`, so both must pass. Discord threads under an allowed parent channel are also allowed; for Forum channels, allowing the parent Forum channel allows all threads/posts in that forum.
> `streaming` defaults to `true`. Disable it only if you explicitly want non-streaming replies.

**5. Invite the bot**
- OAuth2 → URL Generator
- Scopes: `bot`
- Bot Permissions: `Send Messages`, `Read Message History`
- Open the generated invite URL and add the bot to your server

**6. Run**

```bash
nanobot gateway
```

</details>

<details>
<summary><b>Matrix (Element)</b></summary>

Install Matrix dependencies first:

```bash
pip install nanobot-ai[matrix]
```

> [!NOTE]
> Matrix is not supported on Windows. `matrix-nio[e2e]` depends on
> `python-olm`, which has no pre-built Windows wheel and is skipped by the
> `matrix` extra on `sys_platform == 'win32'`. The command above will still
> succeed on Windows but without `matrix-nio` installed, so enabling the
> Matrix channel will fail at startup. Use macOS, Linux, or WSL2.

**1. Create/choose a Matrix account**

- Create or reuse a Matrix account on your homeserver (for example `matrix.org`).
- Confirm you can log in with Element.

**2. Get credentials**

- You need:
  - `userId` (example: `@nanobot:matrix.org`)
  - `password`

(Note: `accessToken` and `deviceId` are still supported for legacy reasons, but
for reliable encryption, password login is recommended instead. If the
`password` is provided, `accessToken` and `deviceId` will be ignored.)

**3. Configure**

```json
{
  "channels": {
    "matrix": {
      "enabled": true,
      "homeserver": "https://matrix.org",
      "userId": "@nanobot:matrix.org",
      "password": "mypasswordhere",
      "e2eeEnabled": true,
      "sasVerification": true,
      "allowFrom": ["@your_user:matrix.org"],
      "groupPolicy": "open",
      "groupAllowFrom": [],
      "allowRoomMentions": false,
      "maxMediaBytes": 20971520
    }
  }
}
```

> Keep a persistent `matrix-store` — encrypted session state is lost if these change across restarts.

| Option | Description |
|--------|-------------|
| `allowFrom` | User IDs allowed to interact. Empty denies all; use `["*"]` to allow everyone. |
| `groupPolicy` | `open` (default), `mention`, or `allowlist`. |
| `groupAllowFrom` | Room allowlist (used when policy is `allowlist`). |
| `allowRoomMentions` | Accept `@room` mentions in mention mode. |
| `e2eeEnabled` | E2EE support (default `true`). Set `false` for plaintext-only. |
| `sasVerification` | Auto-complete SAS device verification requests from allowed users (default `false`). Useful for Element X, which does not expose manual trust for third-party devices. |
| `maxMediaBytes` | Max attachment size (default `20MB`). Set `0` to block all media. |




**4. Run**

```bash
nanobot gateway
```

<details>
<summary><b>WhatsApp</b></summary>

Requires **Node.js ≥18**.

**1. Link device**

```bash
nanobot channels login whatsapp
# Scan QR with WhatsApp → Settings → Linked Devices
```

**2. Configure**

```json
{
  "channels": {
    "whatsapp": {
      "enabled": true,
      "allowFrom": ["+1234567890"]
    }
  }
}
```

**3. Run** (two terminals)

```bash
# Terminal 1
nanobot channels login whatsapp

# Terminal 2
nanobot gateway
```

> WhatsApp bridge updates are not applied automatically for existing installations.
> After upgrading nanobot, rebuild the local bridge with:
> `rm -rf ~/.nanobot/bridge && nanobot channels login whatsapp`

</details>

<details>
<summary><b>Feishu</b></summary>

Uses **WebSocket** long connection — no public IP required.

**1. Create a Feishu bot**
- Visit [Feishu Open Platform](https://open.feishu.cn/app)
- Create a new app → Enable **Bot** capability
- **Permissions**:
  - `im:message` (send messages) and `im:message.p2p_msg:readonly` (receive messages)
  - **Streaming replies** (default in nanobot): add **`cardkit:card:write`** (often labeled **Create and update cards** in the Feishu developer console). Required for CardKit entities and streamed assistant text. Older apps may not have it yet — open **Permission management**, enable the scope, then **publish** a new app version if the console requires it.
  - If you **cannot** add `cardkit:card:write`, set `"streaming": false` under `channels.feishu` (see below). The bot still works; replies use normal interactive cards without token-by-token streaming.
- **Events**: Add `im.message.receive_v1` (receive messages)
  - Select **Long Connection** mode (requires running nanobot first to establish connection)
- Get **App ID** and **App Secret** from "Credentials & Basic Info"
- Publish the app

**2. Configure**

```json
{
  "channels": {
    "feishu": {
      "enabled": true,
      "appId": "cli_xxx",
      "appSecret": "xxx",
      "encryptKey": "",
      "verificationToken": "",
      "allowFrom": ["ou_YOUR_OPEN_ID"],
      "groupPolicy": "mention",
      "reactEmoji": "OnIt",
      "doneEmoji": "DONE",
      "toolHintPrefix": "🔧",
      "streaming": true,
      "domain": "feishu"
    }
  }
}
```

> `streaming` defaults to `true`. Use `false` if your app does not have **`cardkit:card:write`** (see permissions above).
> `encryptKey` and `verificationToken` are optional for Long Connection mode.
> `allowFrom`: Add your open_id (find it in nanobot logs when you message the bot). Use `["*"]` to allow all users.
> `groupPolicy`: `"mention"` (default — respond only when @mentioned), `"open"` (respond to all group messages). Private chats always respond.
> `reactEmoji`: Emoji for "processing" status (default: `OnIt`). See [available emojis](https://open.larkoffice.com/document/server-docs/im-v1/message-reaction/emojis-introduce).
> `doneEmoji`: Optional emoji for "completed" status (e.g., `DONE`, `OK`, `HEART`). When set, bot adds this reaction after removing `reactEmoji`.
> `toolHintPrefix`: Prefix for inline tool hints in streaming cards (default: `🔧`).
> `domain`: `"feishu"` (default) for China (open.feishu.cn), `"lark"` for international Lark (open.larksuite.com).

**3. Run**

```bash
nanobot gateway
```

> [!TIP]
> Feishu uses WebSocket to receive messages — no webhook or public IP needed!

</details>

<details>
<summary><b>QQ (QQ单聊)</b></summary>

Uses **botpy SDK** with WebSocket — no public IP required. Currently supports **private messages only**.

**1. Register & create bot**
- Visit [QQ Open Platform](https://q.qq.com) → Register as a developer (personal or enterprise)
- Create a new bot application
- Go to **开发设置 (Developer Settings)** → copy **AppID** and **AppSecret**

**2. Set up sandbox for testing**
- In the bot management console, find **沙箱配置 (Sandbox Config)**
- Under **在消息列表配置**, click **添加成员** and add your own QQ number
- Once added, scan the bot's QR code with mobile QQ → open the bot profile → tap "发消息" to start chatting

**3. Configure**

> - `allowFrom`: Add your openid (find it in nanobot logs when you message the bot). Use `["*"]` for public access.
> - `msgFormat`: Optional. Use `"plain"` (default) for maximum compatibility with legacy QQ clients, or `"markdown"` for richer formatting on newer clients.
> - For production: submit a review in the bot console and publish. See [QQ Bot Docs](https://bot.q.qq.com/wiki/) for the full publishing flow.

```json
{
  "channels": {
    "qq": {
      "enabled": true,
      "appId": "YOUR_APP_ID",
      "secret": "YOUR_APP_SECRET",
      "allowFrom": ["YOUR_OPENID"],
      "msgFormat": "plain"
    }
  }
}
```

**4. Run**

```bash
nanobot gateway
```

Now send a message to the bot from QQ — it should respond!

</details>

<details>
<summary><b>Napcat (QQ via OneBot v11 支持群聊等功能)</b></summary>

Connects to a [Napcat](https://github.com/NapNeko/NapCatQQ) instance over its **forward WebSocket** (OneBot v11). Use this when you have your own QQ account running through Napcat and want full private + group chat support.

**1. Set up Napcat**

- Install and log into Napcat, then enable a **Forward WebSocket** server. Recommends: [official napcat docker tutorial](https://github.com/NapNeko/NapCat-Docker)
- In the webui, follow "网络配置" -> "新建" -> "Websocket 服务器" to create a forward websocket server. By default, the URL is `ws://127.0.0.1:3001`
- Copy the forward websocket server's token
- (Optional) In the webui, follow "系统配置" -> "登陆配置" -> "快速登录QQ" to automatically login after restarts

**2. Configure**

```json
{
  "channels": {
    "napcat": {
      "enabled": true,
      "wsUrl": "ws://127.0.0.1:3001",
      "accessToken": "YOUR_WEBSOCKET_TOKEN",
      "allowFrom": ["*"],
      "groupPolicy": "mention",
      "groupPolicyOverrides": {
        "123456789": "open",
        "987654321": 0.2
      },
      "welcomeNewMembers": true
    }
  }
}
```

| Option | What it does |
|--------|--------------|
| `wsUrl` | Napcat forward-WebSocket endpoint. Bearer auth via `accessToken` is sent in the `Authorization` header. |
| `allowFrom` | QQ numbers permitted to talk to the bot. `["*"]` = anyone. Required `["*"]` (or include the joining user) for `welcomeNewMembers` to fire. |
| `groupPolicy` | `"mention"` (default) — reply only when @-mentioned or replying to the bot's own message. `"open"` — reply to every group message. A float `p` in `[0.0, 1.0]` — @mentions and replies-to-bot always reply; every other group message replies with probability `p` (so `0.0` ≡ `"mention"`, `1.0` ≡ `"open"`). Private chats always reply. |
| `groupPolicyOverrides` | Optional per-group overrides for `groupPolicy`, keyed by group id (as a string). Each value takes the same shape as `groupPolicy` (`"mention"`, `"open"`, or a float). Groups not listed fall back to `groupPolicy`. |
| `welcomeNewMembers` | When true, `notice.group_increase` events are pushed to the bus as a synthetic message so the agent can greet new joiners. |
| `maxImageBytes` | Hard cap (in bytes) for inbound image downloads. Defaults to 20 MB. Larger images are dropped with a warning. |

<details>
<summary><b>DingTalk (钉钉)</b></summary>

Uses **Stream Mode** — no public IP required.

**1. Create a DingTalk bot**
- Visit [DingTalk Open Platform](https://open-dev.dingtalk.com/)
- Create a new app -> Add **Robot** capability
- **Configuration**:
  - Toggle **Stream Mode** ON
- **Permissions**: Add necessary permissions for sending messages
- Get **AppKey** (Client ID) and **AppSecret** (Client Secret) from "Credentials"
- Publish the app

**2. Configure**

```json
{
  "channels": {
    "dingtalk": {
      "enabled": true,
      "clientId": "YOUR_APP_KEY",
      "clientSecret": "YOUR_APP_SECRET",
      "allowFrom": ["YOUR_STAFF_ID"],
      "groupUserIsolation": false
    }
  }
}
```

> `allowFrom`: Add your staff ID. Use `["*"]` to allow all users.
>
> `groupUserIsolation`: Optional. Defaults to `false`, which keeps one shared session per
> group chat. Set it to `true` to give each sender in a DingTalk group chat a separate
> session while replies still go back to the same group.

**3. Run**

```bash
nanobot gateway
```

</details>

<details>
<summary><b>Slack</b></summary>

Uses **Socket Mode** — no public URL required.

**1. Create a Slack app**
- Go to [Slack API](https://api.slack.com/apps) → **Create New App** → "From scratch"
- Pick a name and select your workspace

**2. Configure the app**
- **Socket Mode**: Toggle ON → Generate an **App-Level Token** with `connections:write` scope → copy it (`xapp-...`)
- **OAuth & Permissions**: Add bot scopes: `chat:write`, `reactions:write`, `app_mentions:read`, `files:read`, `files:write`, `channels:history`, `groups:history`, `im:history`, `mpim:history`
- **Event Subscriptions**: Toggle ON → Subscribe to bot events: `message.im`, `message.channels`, `app_mention` → Save Changes
- **App Home**: Scroll to **Show Tabs** → Enable **Messages Tab** → Check **"Allow users to send Slash commands and messages from the messages tab"**
- **Install App**: Click **Install to Workspace** → Authorize → copy the **Bot Token** (`xoxb-...`)

> `files:read` is required to read files users send to nanobot. `files:write` is required for nanobot to send images, videos, and other file uploads. If you add either scope later, reinstall the Slack app to the workspace and restart nanobot so it uses the updated bot token.

**3. Configure nanobot**

```json
{
  "channels": {
    "slack": {
      "enabled": true,
      "botToken": "xoxb-...",
      "appToken": "xapp-...",
      "allowFrom": ["YOUR_SLACK_USER_ID"],
      "groupPolicy": "mention"
    }
  }
}
```

**4. Run**

```bash
nanobot gateway
```

DM the bot directly or @mention it in a channel — it should respond!

> [!TIP]
> - `groupPolicy`: `"mention"` (default — respond only when @mentioned), `"open"` (respond to all channel messages), or `"allowlist"` (restrict to specific channels).
> - DM policy defaults to open. Set `"dm": {"enabled": false}` to disable DMs.

</details>

<details>
<summary><b>Email</b></summary>

Give nanobot its own email account. It polls **IMAP** for incoming mail and replies via **SMTP** — like a personal email assistant.

**1. Get credentials (Gmail example)**
- Create a dedicated Gmail account for your bot (e.g. `my-nanobot@gmail.com`)
- Enable 2-Step Verification → Create an [App Password](https://myaccount.google.com/apppasswords)
- Use this app password for both IMAP and SMTP

**2. Configure**

> - `consentGranted` must be `true` to allow mailbox access. This is a safety gate — set `false` to fully disable.
> - `allowFrom`: Add your email address. Use `["*"]` to accept emails from anyone.
> - `smtpUseTls` and `smtpUseSsl` default to `true` / `false` respectively, which is correct for Gmail (port 587 + STARTTLS). No need to set them explicitly.
> - Set `"autoReplyEnabled": false` if you only want to read/analyze emails without sending automatic replies.
> - `allowedAttachmentTypes`: Save inbound attachments matching these MIME types — `["*"]` for all, e.g. `["application/pdf", "image/*"]` (default `[]` = disabled).
> - `maxAttachmentSize`: Max size per attachment in bytes (default `2000000` / 2MB).
> - `maxAttachmentsPerEmail`: Max attachments to save per email (default `5`).

```json
{
  "channels": {
    "email": {
      "enabled": true,
      "consentGranted": true,
      "imapHost": "imap.gmail.com",

Uses **signal-cli** daemon in HTTP mode — receive messages via SSE, send via JSON-RPC.

**1. Install signal-cli**

Install [signal-cli](https://github.com/AsamK/signal-cli) and register a phone number:

```bash
signal-cli -u +1234567890 register
signal-cli -u +1234567890 verify <CODE>
```

Start the daemon:

```bash
signal-cli -a +1234567890 daemon --http localhost:8080
```

**2. Configure**

```json
{
  "channels": {
    "signal": {
      "enabled": true,
      "phoneNumber": "+1234567890",
      "daemonHost": "localhost",
      "daemonPort": 8080,
      "dm": {
        "enabled": true,
        "policy": "open"
      },
      "group": {
        "enabled": true,
        "policy": "open",
        "requireMention": true
      }
    }
  }
}
```

> - `phoneNumber`: Your registered Signal phone number.
> - `daemonHost` / `daemonPort`: Where signal-cli daemon is listening (default `localhost:8080`).
> - `dm.policy`: `"open"` (anyone can DM) or `"allowlist"` (only listed numbers/UUIDs). When `"allowlist"`, unlisted DM senders receive a pairing code.
> - `dm.allowFrom`: List of allowed phone numbers or UUIDs (used when policy is `"allowlist"`).
> - `group.policy`: `"open"` (all groups) or `"allowlist"` (only listed group IDs).
> - `group.requireMention`: When `true` (default), the bot only responds in groups when @mentioned.
> - `group.allowFrom`: List of allowed group IDs (used when group policy is `"allowlist"`).
> - `attachmentsDir`: Override the directory where signal-cli stores inbound attachments. Defaults to `~/.local/share/signal-cli/attachments` (the Linux default). Set this if signal-cli runs with a custom `XDG_DATA_HOME` or on macOS/Windows.
> - `groupMessageBufferSize`: Number of recent group messages kept for context (default `20`, must be > 0).

**3. Run**

```bash
nanobot gateway
```

> [!TIP]
> The channel automatically reconnects to the signal-cli daemon with exponential backoff if the connection drops.
> Markdown in bot replies is automatically converted to Signal text styles (bold, italic, code, etc.).
