agent-discord

Agent Discord

A TypeScript CLI tool that enables AI agents and humans to interact with Discord servers through a simple command interface. Features seamless token extraction from the Discord desktop app (with browser fallback) and multi-server support.

Quick Start

# Get server snapshot (credentials are extracted automatically)
agent-discord snapshot

# Send a message
agent-discord message send <channel-id> "Hello from AI agent!"

# List channels
agent-discord channel list

Authentication

Credentials are extracted automatically from the Discord desktop app (or Chromium browser as fallback) on first use. No manual setup required — just run any command and authentication happens silently in the background.

On macOS, the system may prompt for your Keychain password the first time (required to decrypt Discord's stored token). This is a one-time prompt.

IMPORTANT: Always use agent-discord auth extract to obtain tokens. The CLI extracts from the desktop app first, falling back to Chromium browsers if the app isn't installed.

Multi-Server Support

# List all available servers
agent-discord server list

# Switch to a different server
agent-discord server switch <server-id>

# Show current server
agent-discord server current

# Check auth status
agent-discord auth status

Memory

The agent maintains a ~/.config/agent-messenger/MEMORY.md file as persistent memory across sessions. This is agent-managed — the CLI does not read or write this file. Use the Read and Write tools to manage your memory file.

Reading Memory

At the start of every task, read ~/.config/agent-messenger/MEMORY.md using the Read tool to load any previously discovered server IDs, channel IDs, user IDs, and preferences.

• If the file doesn't exist yet, that's fine — proceed without it and create it when you first have useful information to store.
• If the file can't be read (permissions, missing directory), proceed without memory — don't error out.

Writing Memory

After discovering useful information, update ~/.config/agent-messenger/MEMORY.md using the Write tool. Write triggers include:

• After discovering server IDs and names (from server list, snapshot, etc.)
• After discovering useful channel IDs and names (from channel list, snapshot, etc.)
• After discovering user IDs and names (from user list, user me, etc.)
• After the user gives you an alias or preference ("call this the dev server", "my main channel is X")
• After discovering channel structure (categories, voice channels)

When writing, include the complete file content — the Write tool overwrites the entire file.

What to Store

• Server IDs with names
• Channel IDs with names and categories
• User IDs with display names
• User-given aliases ("dev server", "announcements channel")
• Commonly used thread IDs
• Any user preference expressed during interaction

What NOT to Store

Never store tokens, credentials, or any sensitive data. Never store full message content (just IDs and channel context). Never store file upload contents.

Handling Stale Data

If a memorized ID returns an error (channel not found, server not found), remove it from MEMORY.md. Don't blindly trust memorized data — verify when something seems off. Prefer re-listing over using a memorized ID that might be stale.

Format / Example

# Agent Messenger Memory

## Discord Servers

- `1234567890123456` — Acme Dev (default)
- `9876543210987654` — Open Source Community

## Channels (Acme Dev)

- `1111111111111111` — #general (General category)
- `2222222222222222` — #engineering (Engineering category)
- `3333333333333333` — #deploys (Engineering category)

## Users (Acme Dev)

- `4444444444444444` — Alice (server owner)
- `5555555555555555` — Bob

## Aliases

- "dev server" → `1234567890123456` (Acme Dev)
- "deploys" → `3333333333333333` (#deploys in Acme Dev)

## Notes

- User prefers --pretty output for snapshots
- Main server is "Acme Dev"

Memory lets you skip repeated channel list and server list calls. When you already know an ID from a previous session, use it directly.

• Recent messages (id, content, author, timestamp)
• Members (id, username, global_name)

Output Format

JSON (Default)

All commands output JSON by default for AI consumption:

{
  "id": "1234567890123456789",
  "content": "Hello world",
  "author": "username",
  "timestamp": "2024-01-15T10:30:00.000Z"
}

Pretty (Human-Readable)

Use --pretty flag for formatted output:

agent-discord channel list --pretty

Key Differences from Slack

Feature	Discord	Slack
Server terminology	Server	Workspace
Channel identifiers	Snowflake IDs	Channel name or ID
Message identifiers	Snowflake IDs	Timestamps (ts)
Threads	Thread ID field	Thread timestamp
Mentions	<@user_id>	<@USER_ID>

Important: Discord uses Snowflake IDs (large numbers like 1234567890123456789) for all identifiers. You cannot use channel names directly - use channel list to find IDs first.

Common Patterns

See references/common-patterns.md for typical AI agent workflows.

Templates

See templates/ directory for runnable examples:

• post-message.sh - Send messages with error handling
• monitor-channel.sh - Monitor channel for new messages
• server-summary.sh - Generate server summary

Error Handling

All commands return consistent error format:

{
  "error": "Not authenticated. Run \"auth extract\" first."
}

Common errors:

• Not authenticated: No valid token (auto-extraction failed — see Troubleshooting)
• No current server set: Run server switch <id> first
• Message not found: Invalid message ID
• Unknown Channel: Invalid channel ID

Configuration

Credentials stored in ~/.config/agent-messenger/discord-credentials.json (0600 permissions). See references/authentication.md for format and security details.

SDK: Programmatic Usage

DiscordClient is available as a TypeScript SDK for building scripts and automations.

Setup

import { DiscordClient } from 'agent-messenger/discord'

const client = await new DiscordClient().login()

Or with manual credential management:

import { DiscordClient, DiscordCredentialManager } from 'agent-messenger/discord'

const manager = new DiscordCredentialManager()
const token = await manager.getToken()
if (!token) {
  throw new Error('Discord token not found. Run auth extract first.')
}
const client = await new DiscordClient().login({ token })

Example

// Send a message
const msg = await client.sendMessage(channelId, 'Hello from SDK!')

// React to it
await client.addReaction(channelId, msg.id, '👋')

// Search messages
const { results } = await client.searchMessages(serverId, 'deployment', {
  sortBy: 'timestamp',
  sortOrder: 'desc',
  limit: 5,
})

// Create a thread
const thread = await client.createThread(channelId, 'Discussion Topic')
await client.sendMessage(thread.id, 'First message in thread')

Real-Time Events (SDK)

DiscordListener connects to Discord's Gateway WebSocket for instant event streaming:

import { DiscordClient, DiscordListener, DiscordIntent } from 'agent-messenger/discord'

const client = await new DiscordClient().login()
const listener = new DiscordListener(client, {
  intents: DiscordIntent.Guilds | DiscordIntent.GuildMessages | DiscordIntent.MessageContent,
})

listener.on('message_create', (event) => {
  console.log(`${event.author.username}: ${event.content}`)
})

listener.on('error', (err) => console.error(err))

await listener.start()
// listener.stop()

Available events: message_create, message_update, message_delete, message_reaction_add, message_reaction_remove, guild_member_add, guild_member_remove, typing_start, presence_update, channel_create, channel_update, channel_delete, discord_event (catch-all), connected, disconnected, error.

Note: MessageContent, GuildMembers, and GuildPresences are privileged intents — pass them explicitly via options.intents.

Full API Reference

See the Discord SDK documentation for complete method signatures, types, schemas, and examples.

Limitations

• No voice channel support
• No server management (create/delete channels, roles)
• No slash commands
• No webhook support
• Plain text messages only (no embeds in v1)
• User tokens only (no bot tokens)

Troubleshooting

agent-discord: command not found

agent-discord is NOT the npm package name. The npm package is agent-messenger.

If the package is installed globally, use agent-discord directly:

agent-discord server list

If the package is NOT installed, use npx -y by default. Do NOT ask the user which package runner to use — just run it:

npx -y agent-messenger discord server list
bunx agent-messenger discord server list
pnpm dlx agent-messenger discord server list

If you already know the user's preferred package runner (e.g., bunx, pnpm dlx), use that instead.

NEVER run npx agent-discord, bunx agent-discord, or pnpm dlx agent-discord — it will fail or install a wrong package since agent-discord is not the npm package name.

For other troubleshooting (auth extraction, token issues, permissions), see references/authentication.md.
