An account with permission to use the Discord resources you intend to connect.

1. Connect Discord to ApexGenius

Open Discord in Connections. Choose Connect, or Add connection when offered. Give the connection a name if prompted. If Gateway setup pending appears, contact ApexGenius support before continuing.

Review the connected account and resources. Check the Servers list on the connection page Overview. Turn on each server you want; Discord opens with that server already picked. Turn off any channel your AI should not use.
Check the connection. Use Test connection or Check again and read the reported status. Add an AI agent from the AI agents page, choose Read only for the first test, and try the question below.

A public ApexGenius plugin listing is not verified. Use a plugin shared with you or one you created, subject to your account and workspace policy.

You choose the access. When you approve Codex, pick Full access, Read only, or Custom.

The connected server, enabled channels, Discord permissions and explicit tool grants set the access boundary.

Choose Read-only transcripts for history and transcript reads without message-write access. Explicit tool and channel grants still apply. Discord may return incomplete content; the result must state that limit.

Existing message actions keep their separate access and tool controls. Edit, delete and reaction actions are limited to messages owned by the same connection.

Full access turns on the reviewed Discord catalog: 128 tools for channels, threads, messages, roles, members, events, webhooks, AutoMod and more, limited by the bot's Discord role.

Questions about connecting Codex to Discord

Updated September 19, 2026.

Can I add Codex to my Discord server?

Yes, through the ApexGenius bot. Connect Discord in ApexGenius and turn on each server you manage; Discord adds the bot with one Authorize. Codex can then post, @mention people and roles, read the channels you enable, and run reviewed Discord tools there when you ask it. The bot does not reply to members on its own.

How do I connect Codex to Discord?

Connect Codex to Discord through ApexGenius in three steps. Sign in to ApexGenius and connect Discord with Discord OAuth, then pick a server; add more servers from the Servers list later. Add ApexGenius to Codex. Then open a task in Codex and ask a question about your Discord. Start with a read, so nothing changes.

Is there a Discord MCP server for Codex?

Yes. ApexGenius is an MCP server that Codex connects to once. It carries your Discord connection and 14 Discord operations, so Codex does not need a separate Discord integration or plugin. You set it up one time and add each agent the same way.

What can Codex do in Discord once it is connected?

Codex can run 14 Discord operations through ApexGenius: 8 reads that list your servers, their channels and public threads, and read enabled channel history and transcript attachments, and 6 writes that send messages and rich messages that @mention people and roles, and edit, delete or react to messages ApexGenius sent. Full access adds the reviewed catalog of 128 Discord tools for channels, threads, roles, members, events, webhooks and AutoMod, limited by the bot's Discord role.

Can Codex change my Discord?

Yes, when you ask it. Full access is the default, so Codex can send messages that @mention people and roles and run the reviewed Discord tools on the servers you turn on. Choose Read-only transcripts or Minimum access on the Access page to narrow it, and turn off any server, channel or tool. Edits, deletes and reactions apply only to messages this connection sent.

Can I use the same Discord connection with Claude, ChatGPT, Grok Bot or Muse?

Yes. One Discord connection in ApexGenius works with every compatible agent you add, including Claude, ChatGPT, Grok Bot or Muse. Each agent gets its own access choice and its own short setup. The Discord skill loads in all of them, so it travels with the connection.
