Example prompt
“Write an X post about Saturday's market in under 280 characters, with no link, and hold it for my review on Friday at 8am.”

Example prompt
“What's on X for this brand next week? Find the quiet day and draft a text post to fill it.”
ChatGPT works through Wahlu's tools, so it can set the X options Wahlu supports.
Agents can post X threads of up to 25 posts with thread_parts. Polls, quote posts and long posts for X Premium aren't available. X follower and post numbers show in the app on paid plans; agents can't read them yet.
list_targetsFinds the brand's connected X account and checks it's ready.
import_media_from_url, upload_media or list_mediaBrings in the image or video, or picks one from your media library.
create_draftCreates the draft with its caption and x_settings, such as the post type.
preflight_draftChecks the draft against X's rules without changing it.
create_schedulePuts it on the calendar at pending_review, held for your approval.
Wahlu checks these before a post is scheduled, so the agent finds out early.
Posts up to 280 characters by X's count: a link counts as 23 and an emoji as 2.
X: counting charactersImages can be JPEG, PNG or WebP. Wahlu takes images and GIFs up to 5 MB.
X API: media best practicesVideos are MP4 or MOV. Wahlu takes videos up to 512 MB.
X API: media best practicesThe hosted connection can't open files on your computer. Give the agent a public link to import, pick from your brand's media library, or attach an image the agent can pass on as data. For video, a public link or your media library is usually easiest.
Set this up once and ChatGPT can work on every network you've connected, not just X.
On chatgpt.com, open Settings → Security and login and turn on Developer mode.
Go to chatgpt.com/plugins and select the + button.
Name it Wahlu, paste https://mcp.wahlu.com/mcp as the MCP server URL and choose OAuth if asked how to authenticate.
Create the connection and sign in to Wahlu when asked.
Start a new conversation and add Wahlu from the tools menu.
Checked against the OpenAI developer docs on 24 September 2026. Menus can change; if a step doesn't match what you see, follow the vendor's current instructions.
Set this up on the ChatGPT website; the desktop apps don't have developer mode. Whether developer mode is available depends on your ChatGPT plan and workspace settings, and a workspace admin may need to allow it.
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.
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 separate from Manage your schedule. Leave it unticked and nothing your agent schedules can go out on its own.
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.
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.
Connect your X account in Wahlu, then give ChatGPT a specific brief.
