Post to YouTube from Codex
Attach PostWharf to Codex 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
Point the connector at the hosted server and the tools appear alongside the rest. One workspace key scopes every call to a single brand, so Codex can only ever reach the accounts in that workspace — not every account you run.
# Point the connector at: https://mcp.postwharf.com/mcp # with the header: Authorization: Bearer YOUR_WORKSPACE_KEY
Ask for a YouTube post
Once the server is attached the ask is a prompt, not a form — alongside whatever else the agent has been asked to finish:
"Write a description with timestamps for this upload and publish it once the render finishes."
Codex 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.
Treat the post as the last step of a task rather than a task of its own. The agent already knows what it just did, which is most of what the announcement needs to say.
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 Codex for the status and it reads that receipt back rather than guessing.
Questions
Can Codex post to YouTube automatically?
Yes. Connect the PostWharf MCP server to Codex 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, Codex 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.
