Automate TikTok with VS Code
TikTok is the only video platform here that will take a landscape or a square cut, not just a vertical one.
VS Code installs Antwork from a single click, straight into the Copilot chat MCP servers. The one thing that catches people is the extension it rides on.
MCP servers in VS Code run through GitHub Copilot, so the extension has to be installed and signed in.

What is different about TikTok
It is not vertical-only
TikTok accepts 9:16, 16:9 and 1:1. YouTube Shorts takes 9:16 and nothing else, so a cut that posts here will not always go straight to Shorts, and the agent checks before it tries.
One video, and that is the whole post
No images, no carousel, no text-only post. If you ask for a set, the agent tells you at the drafting step rather than building something the publisher will reject.
The largest frame of any platform here
Up to 4096 by 4096, the highest resolution ceiling Antwork will accept anywhere, with ten minutes of runtime at 4 GB. Nothing you export will be too detailed for it.
More caption than the format suggests
The caption runs to 2,200 characters, the same as Instagram. Almost nobody uses it, which is most of the reason a written hook does well here.
TikTok limits, as the server enforces them
Posts are capped at 2,200 characters, and the cap is enforced when you schedule or publish, not silently truncated.
- Max size
- 4 GB
- Per post
- 1
- Ceiling
- up to 4096x4096 · 10 min max · 9:16 / 16:9 / 1:1
- — 1 media items per post, in total.
- — Images and video can never share a post. Ask for both and it has to be split into two.
These numbers are read at build time from the same rules file the publishers validate against, so this page cannot claim a limit the server does not enforce.
Questions
- Do I need an API key to connect VS Code?
- No. Antwork connects over OAuth — you approve a consent screen in the browser and you are done. There is no key to generate or paste into a URL, which is how most social MCP servers handle it.
- Do I need a paid account?
- No. The free tier covers one workspace, two connected accounts and 20 posts per cycle, and there is no plan gate on MCP access.
- Will VS Code post without showing me first?
- Not unless you ask it to. Drafting and publishing are two separate steps: the agent writes, renders the post card, and only publishes when you confirm.
- Does the writing sound like AI?
- Antwork learns a voice profile per connected account by reading what you have already published there, and the agent drafts from that profile. On TikTok that includes writing to the length the format rewards, up to 2,200 characters.
Never leave VS Code to post again.
One command, one consent screen, and TikTok is something you can just ask for.
