“Write a LinkedIn post for my personal profile from the changes in this branch: what changed, who it helps and one honest lesson. Hold it for review.”

Example prompt

Example prompt

“Draft a LinkedIn link post pointing to the release notes for the changes in this branch, then tell me when my next free morning slot is.”

What Wahlu does on LinkedIn

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

LinkedIn settings on a draft

Post type
Text, image, video or link.
Visibility
Anyone, or connections only.

Wahlu posts to LinkedIn personal profiles only. Company Page posting and native LinkedIn articles aren't available.

The tool calls, in order

  1. 01

    list_targetsFinds the brand's connected LinkedIn 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 linkedin_settings, such as the post type.

  4. 04

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

  5. 05

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

LinkedIn limits to know

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

Getting images and video to LinkedIn

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 LinkedIn.

  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 the Wahlu calendar.

Publishing is its own permission

Publish to social accounts 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

Queues, general edits to existing drafts, approvals and connecting social accounts happen in the Wahlu app, not through your agent.

Keep going
