Post to TikTok from Cursor

Attach PostWharf to Cursor once, then publish or schedule TikTok video and photo carousels by asking for them — and get a receipt saying what actually landed.

Connect it

Declared once in mcpServers, then available from the editor while you work. One workspace key scopes every call to a single brand, so Cursor can only ever reach the accounts in that workspace — not every account you run.

{
  "mcpServers": {
    "wharf": {
      "url": "https://mcp.postwharf.com/mcp",
      "headers": { "Authorization": "Bearer YOUR_WORKSPACE_KEY" }
    }
  }
}

Ask for a TikTok post

Once the server is attached the ask is a prompt in the editor, not a form — in the editor, with the changelog or the release notes already open in front of you:

"Take the hook from this script, write a caption under 150 characters and schedule it for 7pm."

Cursor finds your connected TikTok channel, checks the text against the 2,200-character ceiling before anything is queued, and hands back the queued time. Nothing publishes because a model decided it should.

The useful pattern here is turning a diff into an announcement — the file that changed is the context, so the post does not have to be written from memory afterwards.

Publishing goes through an audited API client, so posts go out public rather than private.

What comes back

Every post carries a delivery receipt per channel: the state, the live URL once it is out, and the platform's own reason if it failed. Deliveries are re-checked after publishing, so a TikTok post removed later stops reporting as live instead of sitting in your history as a success. Ask Cursor for the status and it reads that receipt back rather than guessing.

Questions

Can Cursor post to TikTok automatically?

Yes. Connect the PostWharf MCP server to Cursor and it can publish or schedule to a connected TikTok channel, then read the delivery receipt back. The workspace key limits it to the accounts in one workspace, and you keep the approval step.

What do I need before TikTok will work?

Publishing goes through an audited API client, so posts go out public rather than private. Once the channel is connected in PostWharf, Cursor reaches it the same way it reaches every other network.

How long can a TikTok post be?

2,200 characters, counted on the caption. PostWharf checks that before the post is queued, so an over-length post is refused immediately rather than failing at TikTok after everything else in the same batch has already published.
