TikTok MCP Server

Q: What's the TikTok MCP server URL?

https://postonce.to/mcp. It's one hosted server for TikTok and 8 other platforms. Your agent posts to TikTok once your TikTok account is connected.

Q: Can it save a post as a draft in TikTok?

Yes. Set publish_mode to draft and the post lands in your TikTok inbox, where you finish it (add a sound, edit, post) in the app. A video draft arrives without its caption, so paste the caption in TikTok before posting.

A TikTok MCP for organic posts: Claude, ChatGPT or Cursor publishes and schedules videos and photo slideshows through TikTok's official posting API.

TikTok MCP questions

What's the TikTok MCP server URL?

https://postonce.to/mcp. It's one hosted server for TikTok and 8 other platforms. Your agent posts to TikTok once your TikTok account is connected.

Can it run TikTok ads?

No. This server publishes organic videos and photo slideshows to your account. Ads stay in TikTok Ads Manager or TikTok's own ads MCP.

Can Claude post to TikTok?

Yes, once it's connected to an MCP server that can publish, like this one. Claude writes the caption, uploads your video or images, then calls create_post.

Is it safe for my TikTok account?

Yes. Posts go through TikTok's official posting API with the permissions you grant when you connect. There's no scraping and no browser session, and you can revoke access any time.

Do I need a TikTok developer app or API approval?

No. PostOnce holds the TikTok API access; you just connect your account.

Can it post TikTok slideshows (photo mode)?

Yes. Send 1 to 35 JPEG or WEBP images in order and they post as a photo post. TikTok adds music to photo posts automatically; you can't pick the sound through the API.

Can it save a post as a draft in TikTok?

Yes. Set publish_mode to draft and the post lands in your TikTok inbox, where you finish it (add a sound, edit, post) in the app. A video draft arrives without its caption, so paste the caption in TikTok before posting.

Is it free?

The skills are free and MIT-licensed on GitHub. Publishing runs through a PostOnce account, which you can try free for 7 days without entering a card. After that, see pricing.

Can I post to TikTok from my own code?

Yes. The same publishing works through the PostOnce social media posting API with an API key on any paid plan.
