Written setup, step by stepShow

Before you start

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

1. Connect Discord to ApexGenius

  1. 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.
  2. Choose the account and review access. On Discord, choose the intended server and review the ApexGenius app installation. Initial access starts with View Channels. Message actions require additional access.
  3. Review the connected account and resources. Check the server, access mode, and enabled channels on the connection page. Enable only the channels you intend your AI to use.
  4. 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.

Step 1 of 4Open Plugins

The walkthrough uses the original ChatGPT web plugin captures. After connecting, open Codex in the desktop app and start a new task with ApexGenius. A ChatGPT web connection does not verify Codex access.

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.

Create a personal plugin

Where Developer mode is available, open ChatGPT Settings, then Security and login, and enable it. In Plugins, select the plus button, enter ApexGenius and a description, then add this URL under Connection. Create the connection, complete OAuth, and review the tools. Return to Codex in the desktop app and start a new task with the plugin enabled.

Manual setup for developers

Codex CLI is optional. Run these commands, complete browser authorization, then start a new session. Do not paste bearer tokens or static authorization headers.

Register the remote MCP server

codex mcp add apexgenius --url https://server.autom8.pro/mcp

Authorize in your browser

codex mcp login apexgenius

Inspect registered servers

codex mcp list

The desktop app, CLI, and IDE extension share MCP configuration on the same host. The IDE extension does not install plugins. ChatGPT web does not read local Codex configuration.

3. Verify one safe read

List the names of channels enabled for my Discord connection. Do not read or send messages.

Compare the returned account and resource with Discord. Check the connection status separately from the result of the first read.

What Codex can do in Discord

14 operations. Read looks things up and changes nothing. Write changes Discord and runs only when that tool is enabled.

Messages ApexGenius sends

  • discord_send_messageSend one text-only bot message when enabled. Mentions are blocked.
  • discord_send_rich_messageSend a card, one file up to 1 MiB, or a message in an allowed public thread.
  • discord_edit_own_messageEdit only a message created and audited by this ApexGenius connection.
  • discord_delete_own_messageDelete only a message created and audited by this ApexGenius connection.
  • discord_add_reaction_to_own_messageAdd one Unicode reaction to an ApexGenius-owned message.

You choose what Codex can use

When you approve Codex, pick Full access, Read only, or Custom. Read only allows the Read operations and nothing else. Custom picks apps and tools one by one.

Limits in Discord

  • · 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.
  • · The larger Discord MCP catalog remains separately staged. This release does not turn its worker or additional categories on.

Questions people ask first

How do I connect Discord?

Choose Discord in ApexGenius Connections, select Connect, sign in on Discord and pick one server. You need the right to install the app there. Review the server and enabled channels when you return.

Can I start with channel names only?

Yes. Minimum access starts with channel visibility. Enable only the channels your agent needs and choose Read only for the first test.

Can my agent read channel history?

Choose Read-only transcripts and explicitly enable the history tool and intended channels to read permitted messages. Discord content restrictions still apply, and a response can report incomplete content.

Does this give my agent every Discord action?

No. Account permissions, access mode, enabled resources and tool grants determine the available actions. Writes run when their tools are enabled. The larger MCP worker remains separately staged.

Can I take this setup to another AI agent?

Add ApexGenius to another compatible agent using the same ApexGenius account. It can use the allowed connection and load the Discord skill. Each agent needs its own setup and access choices.
