Post to YouTube from Claude

Attach PostWharf to Claude once, then publish or schedule YouTube Shorts and long-form uploads by asking for them — and get a receipt saying what actually landed.

Connect it

A command for Claude Code, or a connect link for the Claude apps. One workspace key scopes every call to a single brand, so Claude can only ever reach the accounts in that workspace — not every account you run.

  --header "Authorization: Bearer $POSTWHARF_KEY"

Ask for a YouTube post

Once the server is attached the ask is a chat message, not a form — in whatever conversation you are already having, next to the draft rather than in another tab:

"Write a description with timestamps for this upload and publish it once the render finishes."

Claude finds your connected YouTube channel, checks the text against the 5,000-character ceiling before anything is queued, and hands back the queued time. Nothing publishes because a model decided it should.

Claude will show you the post before it queues it. That is the approval step, and it is worth keeping even once you trust the setup — the receipt tells you what published, but only you can tell it what was worth publishing.

What YouTube accepts

A daily upload quota applies; the queue paces around it rather than failing the post.

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 YouTube post removed later stops reporting as live instead of sitting in your history as a success. Ask Claude for the status and it reads that receipt back rather than guessing.

Questions

Can Claude post to YouTube automatically?

Yes. Connect the PostWharf MCP server to Claude and it can publish or schedule to a connected YouTube 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 YouTube will work?

A daily upload quota applies; the queue paces around it rather than failing the post. Once the channel is connected in PostWharf, Claude reaches it the same way it reaches every other network.

How long can a YouTube post be?

5,000 characters, counted on the description. PostWharf checks that before the post is queued, so an over-length post is refused immediately rather than failing at YouTube after everything else in the same batch has already published.
