Connect your Meta, TikTok and X accounts to Arcads so Mark, the AI agent, can read how your ads and posts perform. Mark can also publish organic posts and publish ads for you. Nothing is posted or published until you approve it.
Who can use it
Workspaces that can use Mark, which is included from the Starter plan up to Business Plan, you need your own login for each network, with access to the ad accounts you want to use.
Where to find it
Agent > Connectors. Meta Ads and TikTok Ads are under Ad platforms. X (Twitter) and TikTok are under Social. You can also click Manage all integrations at the bottom of the panel to open the Integrations settings page.
How to use it
Open Agent and pick your brand.
Click Connectors, then click Connect next to Meta Ads, TikTok Ads, X (Twitter) or TikTok, and sign in to that network.
Meta Ads: open Select business accounts and tick the ad accounts this brand should use.
TikTok Ads: open Select advertisers and tick the advertisers this brand should use.
X: under Accounts for [your brand], turn on the X accounts Mark can use for this brand. X accounts are connected once for the workspace, and each brand picks its own.
TikTok: click View posts to check your recent videos.
Ask Mark in the chat, for example "How are my Meta campaigns doing?", "Show my best X posts this month", "Post this video on TikTok" or "Publish this ad on Meta in a new campaign".
When Mark shows a recap, a draft or a confirmation card, check it and approve it. Nothing goes out before you do.
Options
Read performance: Meta campaigns and ads, TikTok ads, X Ads campaigns, promoted posts and the audience they reached, and your X and TikTok posts with views, likes, replies and reposts. For X, Mark can also give follower and following counts.
Search your X posts: Mark can search your own X account's posts from the last 7 days for a word, phrase or hashtag.
Publish on X: a post, a reply or a quote repost. Each one can have up to 4 images, or 1 video, or 1 GIF.
Publish on TikTok: Mark opens TikTok's own post form. There you choose who can view the video, whether people can comment, Duet or Stitch, and whether it is promotional content. The caption can be up to 2,200 characters.
Publish a Meta ad: in a new campaign or an existing one. Mark copies the setup from your recent campaigns (objective, budget, audience, Page, link, call to action), writes the copy, suggests UTM tags and shows you a recap. Approving it puts the ad live and starts spending the daily budget, unless you ask Mark to create it paused. Meta reviews the ad before it starts delivering.
Publish a TikTok ad: Mark creates the campaign, ad group and ad, with budget, audience, landing page and call to action taken from your past campaigns. A confirmation card shows everything first. The ad is created paused unless you ask for it to go live, and it carries TikTok's AI-generated label.
Send a video to your TikTok Ads library: the video is ready to use in TikTok Ads Manager. No ad is created.
Publish an X ad: either a promoted-only post, which stays off your public timeline and does not spend anything until you build a campaign around it in X Ads Manager, or a post added to an existing ad group, where it takes that group's settings and status. Mark never changes a group's budget, audience or objective.
Credits
Connecting accounts is free.
Reading Meta, TikTok and X Ads performance, and reading TikTok posts, costs no credits.
Reading X posts is charged per post returned: about 0.6 credits per post, rounded up per request.
Publishing an X post, or creating a new post for an X ad, costs 2 credits, or 24 credits if the post contains a link. The approval card shows the exact cost before anything is posted.
Publishing Meta and TikTok ads, posting on TikTok and sending videos to the TikTok Ads library cost no credits.
Your chat with Mark is charged by usage as usual. Your ad spend is billed by Meta, TikTok or X, not by Arcads.
Where it works
Mark (Agent page): everything in this article.
Arcads MCP and API: read only. You can read X Ads campaigns, creatives and audience, your connected X and TikTok posts, and your brand's own ads. Publishing is not available there.
Studio and Workflows: not available.
Limitations
TikTok accounts connected before October 24, 2026 must be reconnected before Mark can post. Go to Agent > Connectors > TikTok and reconnect.
One TikTok account per workspace. Up to 50 TikTok advertisers per brand.
TikTok ads and TikTok posts only accept videos made or uploaded in Arcads. Image ads and Smart+ campaigns are not supported on TikTok.
Mark can't publish posts or ads during scheduled routines, because publishing always needs your approval.
X search only covers the last 7 days. X follower lists are not available, only the counts.
If a connection expires, reconnect it from Agent > Connectors.
