eBay Creating/Publishing Listings

Is there a specific app this action is for?

eBay, specifically seller listing management through Pipedream MCP for use in ChatGPT.

Please provide a link to the relevant API docs for the specific service / operation.

[Publish offer](https://developer.ebay.com/api-docs/sell/inventory/resources/offer/methods/publishOffer)

What would you like these actions to do?

Please add MCP tools that allow an AI assistant to:

* Create an inventory item with photos/image URLs, title, description, condition, item specifics, SKU, and quantity.
* Create an unpublished fixed-price offer with price, category, inventory location, and shipping/return/payment policies.
* Retrieve the unpublished offer for review.
* Publish the offer as a live eBay listing after my approval, returning the listing ID and URL.

Supporting tools for retrieving existing seller policies and inventory locations would help make the workflow usable.

Use case and current limitation

I sell secondhand clothing and vintage items. I want to provide photos and measurements to ChatGPT, review the prepared listing, and authorize publication to my eBay account.

I successfully connected eBay to Pipedream and added Pipedream MCP to ChatGPT. However, Pipedream’s eBay page says there are no tools available, and ChatGPT shows no app actions.

Please make these actions available through MCP using Pipedream-managed eBay authorization, if supported, so sellers do not need their own eBay developer account. Please clarify whether the existing connection supports the necessary seller permissions or requires reauthorization.

No implementation files or tests are named. Start by locating the eBay integration and its MCP tool definitions, then review how seller authorization and permissions are handled. Done means tools can create and review inventory offers, publish an approved offer, return its listing details, and support the required seller policies and inventory locations.
