How to post to TikTok from Claude, and schedule the posts

Set it up and post, step by step

Prompt to copy once TikTok is connected: Write a TikTok caption for the video I'm about to upload, show it to me, and schedule it public for Friday at 7pm New York time.

1. Add PostWire to Claude

   Open PostWire in Claude's connector directory and press Connect; it works in Claude on the web, on the desktop and on your phone. In Claude Code, run claude mcp add --transport http postwire https://postwire.io/api/mcp. A sign-in window asks for your email and a 6-digit code, which also creates a free PostWire account if you have none: no password and no card.

2. Connect your TikTok account

   Ask "connect my TikTok". Claude calls create_connect_link and gives you a link; open it, sign in on TikTok's own page and allow PostWire to post. You do this once per account.

3. Give it the video, or photos

   A file attached to the chat does not reach a connector, so Claude gives you an upload page instead (create_upload_link, valid 24 hours, up to 100 MB on the free plan and 1 GB on paid plans). Pick the video there and Claude attaches it to the post. A public https link works too. Photos instead of a video make a TikTok photo post of up to 35 images (PNG is turned into JPEG for you). No video yet? make_video_from_text turns a few lines into an 8-12 second vertical MP4 (1080×1920) to show you before anything is posted.

4. Ask for the caption and pick who sees it

   "Write the caption." generate_posts returns a draft and publishes nothing: a hook-first line and a few specific hashtags, within TikTok's 2,200 characters. Then say who can see it: public, friends (mutual followers) or private. TikTok asks the account owner to choose this for every post; if nobody chooses, PostWire posts it private and says so in the result.

5. Publish now, or schedule it

   Say "post it" and Claude calls post_to_social. Say "schedule it for Friday at 7pm" and it calls schedule_post, up to 365 days ahead, or with run_at: "next_slot" for your next free posting hour. This is the call:

   {
     "name": "schedule_post",
     "arguments": {
       "platforms": ["tiktok"],
       "per_platform": { "tiktok": {
         "text": "We cut our build from 9 minutes to 2. Here is the one change. #devtools #ci #buildinpublic"
       } },
       "video_url": "https://postwire.io/m/…/launch.mp4",
       "privacy": "public",
       "run_at": "2026-11-06T19:00:00-05:00"
     }
   }

6. Get the link

   TikTok processes the video after the call returns. Claude calls get_post_status with the returned id until it has the TikTok link, usually within a minute or two. If TikTok refuses the video, the result carries a code, what happened and the fix.

"What's scheduled on TikTok?" calls list_scheduled_posts and "cancel Friday's TikTok" calls cancel_scheduled_post; the same queue is on the dashboard's Queue page. Prefer to set it up by hand first? Open the dashboard, connect the account under Accounts and copy your key under API & MCP.
