Comparison

eBay MCP servers and Claude connectors, compared

There are four realistic ways to connect Claude to an eBay store in 2026. Two are free but run on your own computer and require your own eBay developer account. One is read-only. Haulbound is hosted, costs $19 a month, and is the one that needs neither a developer account nor an install — but it cannot create listings, and the free options have far more API coverage.

What it takes to get started

Steps counted from each vendor's own setup documentation. This is the difference that matters most for a non-technical seller, because the free options all begin with an application that eBay reviews.

The part most sellers don't expect: using any local eBay MCP server makes you an eBay developer. That means an application eBay reviews, and it attaches eBay's developer obligations to you personally — including handling their marketplace account-deletion notifications before your first production call.

Which one should you actually use?

If you write code, use the free open-source server — it has roughly twenty times the API coverage and costs nothing. If you want a read-only view across many business apps, CorpusIQ covers 40+ at a similar price. If you want to change things in your eBay store without becoming an eBay developer, that is what Haulbound is for.

Use the free open-source server if…

You are comfortable installing Node.js, registering as an eBay developer, generating API keys and editing a JSON config file — and you want the widest possible API surface. It is genuinely capable and it costs nothing. Two things to weigh: it runs only while your computer is on, and its fulfilment tools include refunds and payment disputes with no confirmation step in the server.

Use eBay's official MCP server if…

You are a developer exploring eBay's APIs. It is read-only by design and cannot change anything in a store, which makes it a poor fit for actually running one.

Use CorpusIQ if…

You want one connector covering many business apps and you only need to read. It connects the same easy way Haulbound does, at $29.95 a month, but its connection is read-only — it can tell you an order is late, it cannot mark it shipped.

Use Haulbound if…

You sell on eBay, you are not a developer, and you want to ask about orders, fees, payouts and stock — and act on the answers. $19 a month, two clicks to connect, and every change previews and waits for your confirmation before anything happens.
