Codex + Wahlu

Post to Discord from Codex with Wahlu

Connect Codex to Wahlu once, then plan, draft and schedule posts for Discord servers where you have Manage Server, posting to the channel you choose from the Codex CLI, IDE extension and app. Every schedule can wait for your approval.

What Codex can prepare on Discord
  • Text message

    Up to 2,000 characters. Links show a preview.

  • Images and videos

    Up to 10 files, each up to 20 MB and 24 MB together. Text is optional.

Ask Codex for Discord posts

Example prompts and the steps to expect. These are illustrations, not recorded conversations.

Example prompt

“Read the changes in this branch and write a Discord announcement for the release, published to following servers. Hold it for review tomorrow at 9am.”

Example prompt

“Create a Discord message with the screenshots in docs/launch for the changes in this branch, then run a readiness check.”

Example prompt

“Check whether anything is already scheduled on Discord this week before you draft an update about the changes in this branch.”

What Wahlu does on Discord

Codex works through Wahlu's tools, so it can set the Discord options Wahlu supports.

Discord settings on a draft

Post type
A message, or a message with files.
Publish to following servers
In an announcement channel, also send the post to servers that follow it.

Wahlu posts to one channel per server connection and doesn't post embeds, polls or into Discord threads. Discord has no Insights for bots.

The tool calls, in order

  1. 01

    list_targetsFinds the brand's connected Discord account and checks it's ready.

  2. 02

    upload_media, import_media_from_url or list_mediaBrings in the image or video, or picks one from your media library.

  3. 03

    create_draftCreates the draft with its caption and discord_settings, such as the post type.

  4. 04

    preflight_draftChecks the draft against Discord's rules without changing it.

  5. 05

    create_schedulePuts it on the calendar at pending_review, held for your approval.

Discord limits to know

Wahlu checks these before a post is scheduled, so the agent finds out early.

Getting images and video to Discord

The agent can read a file in your project and upload it with upload_media. Files over 8 MB, including most video, go to a short-lived upload link the agent sends the file to. Public links and your media library work too.

Connect Codex to Wahlu

Set this up once and Codex can work on every network you've connected, not just Discord.

  1. 1

    Run codex mcp add to add Wahlu. It's saved in ~/.codex/config.toml, which the Codex CLI, IDE extension and app share.

  2. 2

    Run codex mcp login wahlu and sign in to Wahlu in the browser that opens.

  3. 3

    Start a new Codex session so it picks up Wahlu's tools.

Checked against the Codex docs on 27 September 2026. Menus can change; if a step doesn't match what you see, follow the vendor's current instructions.

Add Wahlu to Codex
codex mcp add wahlu --url https://mcp.wahlu.com/mcp
codex mcp login wahlu

In the Codex IDE extension or app you can add it from the gear menu instead: MCP servers → Add server, choose Streamable HTTP and paste the URL, then restart. Codex signs in with a Client ID Metadata Document, which is what Wahlu uses.

You stay in control.

Every Wahlu plan includes agent access, through MCP and the API. You choose the workspace, brands and permissions each connection gets, and can disconnect it at any time.

Held until you approve

Agents create schedules at pending_review unless you've told them to publish. A held schedule can't publish until you approve it in Wahlu or ask an agent with Publishing permission to approve it.

Publishing is its own permission

Publishing is separate from Manage your schedule. Leave it unticked and nothing your agent schedules can go out on its own.

Checked before it's scheduled

preflight_draft reports anything that would stop a post, such as media the network won't accept or a caption that's too long, without changing anything.

Some things stay in the app

Use the app for queues, draft media and platform settings, and connecting social accounts. Agents can change the name or caption of an unused draft and approve held schedules with the right permissions.
