“Summarise CHANGELOG.md as a Facebook Page post for customers, not developers. Use the hero image at its public link and hold the schedule for review.”
Claude Code + Wahlu
Post to Facebook from Claude Code with Wahlu
Connect Claude Code to Wahlu once, then plan, draft and schedule posts for Facebook Pages connected to Wahlu from the Claude Code terminal and IDE extensions. Every schedule can wait for your approval.
Page post
One image or video with a caption.
Reel
One vertical video.
Story
One image or video. Stories don't take a caption.
Ask Claude Code for Facebook posts
Example prompts and the steps to expect. These are illustrations, not recorded conversations.
Example prompt
“Draft a Facebook Reel from the walkthrough video linked in CHANGELOG.md, then run a readiness check and tell me what needs fixing.”
Example prompt
“Before drafting anything about CHANGELOG.md, show me what's already on the Facebook calendar this week.”
What Wahlu does on Facebook
Claude Code works through Wahlu's tools, so it can set the Facebook options Wahlu supports.
Facebook settings on a draft
- Post type
- Page post, Reel or Story.
Wahlu posts to Facebook Pages, not personal profiles or groups, and a Page post carries one image or video rather than an album.
The tool calls, in order
- 01
list_targetsFinds the brand's connected Facebook account and checks it's ready. - 02
upload_media,import_media_from_urlorlist_mediaBrings in the image or video, or picks one from your media library. - 03
create_draftCreates the draft with its caption andfacebook_settings, such as the post type. - 04
preflight_draftChecks the draft against Facebook's rules without changing it. - 05
create_schedulePuts it on the calendar atpending_review, held for your approval.
Facebook limits to know
Wahlu checks these before a post is scheduled, so the agent finds out early.
Page photos can be JPEG, BMP, PNG, GIF or TIFF, up to 10 MB.
Graph API: Page photosReels are 9:16 video between 3 and 90 seconds. Wahlu keeps Reel captions to 2,200 characters.
Meta: Reels publishingStory videos are 9:16, at least 540 × 960, between 3 and 60 seconds.
Meta: Page Stories APIMeta documents no caption limit for Page posts through the API; Wahlu uses Facebook's own composer limit of 63,206 characters.
Graph API: Page photos
Getting images and video to Facebook
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 Claude Code to Wahlu
Set this up once and Claude Code can work on every network you've connected, not just Facebook.
- 1
Run
claude mcp add(the command shown here) in your project. - 2
In Claude Code, run
/mcp, select wahlu and sign in to Wahlu in the browser that opens.
Checked against the Claude Code docs on 24 September 2026. Menus can change; if a step doesn't match what you see, follow the vendor's current instructions.
claude mcp add --transport http wahlu https://mcp.wahlu.com/mcpThis adds Wahlu to the current project. To use it in every project, add --scope user before wahlu. If Wahlu's tools don't appear, start a new Claude Code session.
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
