Discord Plugin

Overview

The Discord Plugin (@tokenring-ai/discord) provides comprehensive Discord integration for TokenRing agents, enabling AI-powered interactions through Discord's messaging system. The package supports a multi-bot architecture with channel-based routing, direct message support, and built-in escalation provider integration.

Key Features

• Multi-bot architecture: Run multiple Discord bots with independent configurations simultaneously
• Channel-based routing: Configure specific agents for different Discord channels
• Direct message support: Enable DM interactions with configurable user authorization
• Per-channel agent isolation: Each channel maintains persistent agent context
• Buffered streaming responses: Intelligent message chunking with 250ms rate limiting
• Message editing: Update existing messages instead of creating new ones
• Attachment handling: Process file attachments with configurable size limits (default 20MB)
• Escalation integration: Built-in DiscordEscalationProvider for admin communications
• Reply-tracked communication: Track user replies to bot messages for escalation workflows
• Graceful shutdown: Clean agent cleanup and bot disconnection
• Authorization controls: Per-channel and per-user access restrictions
• Join announcements: Optional welcome messages when bots join channels

Integration with TokenRing Ecosystem

This plugin integrates with the TokenRing agent system, allowing Discord users to interact with AI agents through Discord's messaging platform. The plugin creates a separate agent for each Discord channel, maintaining individual conversation contexts. It also integrates with the escalation system for admin communications.

Provider Documentation

DiscordEscalationProvider

The package provides a built-in escalation provider for Discord-based admin communications.

Provider Interface: EscalationProvider

Configuration Schema:

export const DiscordEscalationProviderConfigSchema = z.object({
  type: z.literal('discord'),
  bot: z.string(),
  channel: z.string(),
});

Provider Registration:

• Registered automatically when escalation configuration includes providers with type: "discord"
• Can also be registered programmatically with EscalationService.registerProvider()

Usage:

• Creates communication channels for escalation workflows
• Routes escalation messages to specified Discord channels
• Supports both guild channels and direct messages

RPC Endpoints

This package does not expose RPC endpoints. Communication is handled through Discord's native messaging system and the escalation service's communication channel interface.

Chat Commands

The Discord plugin does not define traditional slash commands. Instead, it processes messages through Discord's native messaging:

Message Processing

Guild Channel Messages:

• Bot must be mentioned to trigger processing (e.g., @BotName what is the weather?)
• Mention is stripped from the message content
• Message is sent to the channel's agent

Direct Messages:

• Any message to the bot is processed (if DMs are enabled)
• No mention required

Reply Messages:

• Replies to bot messages are tracked for escalation workflows
• Reply content is sent back to the agent as user input

Authorization

Channel Authorization:

• allowedUsers: string[] - Empty array allows all users
• Non-empty array restricts to specified user IDs
• Unauthorized users receive "Sorry, you are not authorized."

DM Authorization:

• dmAllowedUsers: string[] - Empty array allows all users (if dmAgentType is set)
• Non-empty array restricts to specified user IDs
• Unauthorized users receive "Sorry, you are not authorized to DM this bot."

};

Integration

Plugin Registration

The package provides a TokenRing plugin that automatically registers services:

import discordPlugin from "@tokenring-ai/discord/plugin";

const app = new TokenRingApp();
await app.installPlugin(discordPlugin, {
  discord: {
    bots: {
      primary: {
        name: "Primary Bot",
        botToken: process.env.DISCORD_BOT_TOKEN!,
        channels: {
          general: {
            channelId: "123456789012345678",
            allowedUsers: [],
            agentType: "teamLeader"
          }
        }
      }
    }
  }
});

Service Registration

The plugin automatically registers:

• DiscordService: Manages bot instances
• DiscordEscalationProvider: Registered with EscalationService for providers with type: "discord"

Programmatic Registration

import TokenRingApp from "@tokenring-ai/app";
import DiscordService from "@tokenring-ai/discord/DiscordService";
import { DiscordEscalationProvider } from "@tokenring-ai/discord";
import { EscalationService } from "@tokenring-ai/escalation";

const app = new TokenRingApp();

// Register Discord service directly
const discordService = new DiscordService(app, {
  bots: {
    primary: {
      name: "Primary Bot",
      botToken: process.env.DISCORD_BOT_TOKEN!,
      channels: {
        general: {
          channelId: "123456789012345678",
          allowedUsers: [],
          agentType: "teamLeader"
        }
      }
    }
  }
});

app.addServices(discordService);

// Register escalation provider
app.waitForService(EscalationService, (escalationService) => {
  escalationService.registerProvider(
    "discordAdmins",
    new DiscordEscalationProvider({
      type: "discord",
      bot: "primary",
      channel: "general"
    })
  );
});

Agent Integration

Each Discord channel maintains its own agent instance:

• Agents are spawned on first message to a channel
• Agent context persists for the channel's lifetime
• Background event loops process agent outputs
• Agents are cleaned up on bot shutdown

Event Handling

The package handles Discord events:

• messageCreate: Processes incoming messages
• Bot mentions trigger agent interactions in guild channels
• Direct messages are handled separately
• Reply tracking enables escalation workflows

Gateway Intents

The Discord client uses the following Gateway Intents:

• GatewayIntentBits.Guilds: Server/guild operations
• GatewayIntentBits.GuildMessages: Guild message events
• GatewayIntentBits.MessageContent: Message content access
• GatewayIntentBits.DirectMessages: Direct message events

Best Practices

Bot Token Security

• Store tokens in environment variables
• Never commit tokens to version control
• Use different tokens for development and production

Channel Authorization

• Use allowedUsers to restrict channel access
• Empty allowedUsers array allows all users
• Combine with Discord role-based permissions

Message Rate Limiting

• The package implements 250ms rate limiting automatically
• Large responses are automatically chunked
• Message edits are preferred over new messages

Attachment Handling

• Set appropriate maxFileSize limits
• Monitor attachment processing errors
• Consider bandwidth implications for large files

Agent Configuration

• Use distinct agentType values per channel
• Configure appropriate agent capabilities per use case
• Monitor agent resource usage for high-traffic channels

Escalation Setup

• Configure dedicated channels for escalation
• Use specific bot instances for admin communications
• Test escalation workflows before production use

Multi-bot Architecture

• Use separate bots for different purposes (e.g., primary, admin, support)
• Configure appropriate channels for each bot
• Monitor resource usage across multiple bots
