How to post to TikTok from Claude Desktop

1. 1

   Create an API key and add planpo.st to Claude Desktop

   Make a scoped key in planpo.st under Settings. Open Settings, then Connectors, then Add custom connector, and enter the planpo.st URL with an Authorization header. Or add the local npx entry to claude_desktop_config.json and restart the app, since it reads that file only on launch.

2. 2

   Confirm the server is connected

   Start a new chat and check that the planpost tools appear in the tools menu.

3. 3

   Connect TikTok

   Connect the TikTok account in the dashboard under Connections. Publishing goes through TikTok's Content Posting API as a direct post, and get_connection_link gives the agent a URL to hand you.

4. 4

   Know what the post needs

   A TikTok post needs one video and platformSettings.tiktok.privacyLevel. TikTok makes the account owner choose who can view each video, so there is no default to fall back on.

5. 5

   Ask in a chat window

   Say what to post and when. Claude Desktop finds the TikTok connection, creates the post, and tells you whether it was scheduled or kept as a draft, with the reason.

Settings -> Connectors -> Add custom connector

Name:  PlanPost
URL:   https://mcp.planpo.st/mcp

Then add the header:
Authorization: Bearer pk_live_xxx

{
  "mcpServers": {
    "planpost": {
      "command": "npx",
      "args": ["-y", "planpost-mcp"],
      "env": { "PLANPOST_API_KEY": "pk_live_xxx" }
    }
  }
}

TikTok needs a video file on every post, and that is the one awkward part of this pairing. Claude Desktop reaches planpo.st through the connector and has no shell to PUT a file from your disk to an upload URL. Two routes work: upload the file in the planpo.st dashboard and let Claude Desktop pick it with list_media, or ask for a video rendered from a template with create_video.
