What Wahlu does on Bluesky

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

Bluesky settings on a draft

Post type
Text, image or video.
Alt text
A description of each image or video for screen readers.

Agents can post Bluesky threads of up to 25 posts with thread_parts. Quote posts aren't available. Video needs a verified email on Bluesky. Bluesky follower and post numbers show in the app on paid plans; agents can't read them yet.

The tool calls, in order

  1. 01

    list_targetsFinds the brand's connected Bluesky 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 bluesky_settings, such as the post type.

  4. 04

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

  5. 05

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

Bluesky limits to know

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

Getting images and video to Bluesky

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 Bluesky.

  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.

Keep going
