Post to Pinterest from Codex

Attach PostWharf to Codex once, then publish or schedule Pinterest pins and idea pins 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.

Ask for a Pinterest 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 pin description for this image, point it at the product page and pin it to Recipes."

Codex finds your connected Pinterest channel, checks the text against the 500-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.

Every pin needs a destination link and a board, so a post with neither is refused before it is queued.

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 Pinterest 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 Pinterest automatically?

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

Every pin needs a destination link and a board, so a post with neither is refused before it is queued. Once the channel is connected in PostWharf, Codex reaches it the same way it reaches every other network.

How long can a Pinterest post be?

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