Connect eBay to ChatGPT or Claude: eBay’s own MCP server, open-source servers and hosted ones

Before you start

In shortYou need an eBay seller account, an AI app that accepts MCP servers, and a list of jobs.

What an eBay MCP server is

In shortIt is a connector that gives an AI app tools to read your eBay data or change it.

eBay MCP servers compared

In shortSix options on the same points: who runs it, sign-in, AI apps, what it does, price, last update.

Does eBay have its own MCP server?

In shortYes. eBay’s server is a developer tool that reads eBay data and changes nothing in production.

Which eBay MCP fits which seller

In shortHosted for no-code questions, open source for changes with your own keys, eBay’s own for API work.

How to connect an eBay MCP server safely

1. Step 1 of 7: Write down what the AI may do

   In shortList the questions and changes you want, and mark each one read or change.

   A server can only do what its tools allow. Some tools only read, like “list my orders”. Others change your store, like “lower this price”. So start with your own list, not the server’s.

   • QuestionsWhich orders ship today? Which listings get views but no sales? What did I pay in fees last month?
   • Small changesFix one title, add a tracking number, reply to one buyer.
   • Bulk changesNew handling time on every listing, a price cut on a whole category.

   Mark each line read or change. If your list has only questions, choose a read-only connection. A server that cannot change anything cannot make a costly mistake either.

   Bulk changes need the most care. An AI repeats a wrong price on every listing as fast as a right one.

   Result: A short list of jobs for the AI, each marked read or change.

   Mark this step as doneNext: Choose a hosted server or one on your computer

2. Step 2 of 7: Choose a hosted server or one on your computer

   In shortHosted servers need a sign-in. Servers on your computer need eBay developer keys and Node.js.

   There are two kinds of eBay MCP server. Your list from step 1 and your comfort with setup decide which one fits.

   • HostedA company runs it. You sign in to that company, and it calls eBay for you. Frooition for eBay and Zapier work this way. Setup takes minutes, and it works in ChatGPT on the web.
   • On your computerYou install it, and it calls eBay with your own developer keys. eBay’s own server and the two open-source ones work this way. You need Node.js, and your AI app must run on the same computer.

   A hosted server also sees your data. Read its privacy page before you connect. A server on your computer keeps your keys there, but you install and update it yourself.

   Pick a server whose tools match your list, and nothing more. 379 tools sound useful, but each change tool is one more way for a mistake to reach eBay. YosefHayim/ebay-mcp lets you register only some tool groups, or read-only tools alone.

   Result: One kind chosen, hosted or on your computer, and one or two servers to try.

3. Step 3 of 7: Keep eBay keys out of the chat

   In shortFor a server on your computer, create keys at eBay Developers and type them only into its setup.

   Hosted servers need no keys, so skip to step 4. A server on your computer needs an eBay developer account. The READMEs of all three point to the same place:

   1. Create a free account at eBay Developers.
   2. Create a keyset and copy the Client ID and Client Secret.
   3. To read your own orders and listings, sign in to eBay once to get a user token. YosefHayim’s setup wizard and jbwashington’s /ebay-auth command open eBay’s sign-in for you.
   4. Put the keys in the server’s config file or setup wizard, on your computer.

   Never paste a Client Secret or a token into a chat. Whatever you type in ChatGPT or Claude goes to that company’s servers. Some setup prompts have spaces for your keys: leave those blank, and type the keys into the wizard instead. eBay’s README adds: never commit keys to code, and never show tokens in screenshots.

   Test in eBay’s sandbox first if the server allows it. jbwashington’s README starts with a sandbox keyset. eBay’s own server does not support the sandbox yet.

   Result: eBay developer keys saved in the server’s setup on your computer, and nowhere else.

   Mark this step as doneNext: Add the server to Claude

4. Step 4 of 7: Add the server to Claude

   In shortIn Claude, open Customize › Connectors and add the server’s address as a custom connector.

   Anthropic calls an MCP server you add yourself a custom connector. Its connector docs give these steps for a hosted server:

   1. Go to Customize › Connectors.
   2. Click Add custom connector.
   3. Enter the server’s address, the remote MCP server URL.
   4. Click Add. If the server asks, sign in on the page it opens.

   This works on the Free, Pro and Max plans. The Free plan allows one custom connector. On Team and Enterprise plans, an Owner adds it in Organization settings › Connectors. Each member then connects with their own account.

   A server in Claude’s own directory needs no address. Frooition’s page, for example, says to search for it under Connectors and click Connect.

   A server on your computer runs in Claude Desktop or Claude Code instead. In Claude Code, eBay’s README uses one command, claude mcp add, with your keys as settings. YosefHayim’s wizard writes the Claude Desktop config file for you.

   Result: The server added in Claude, signed in, and its tools listed.

   Mark this step as doneNext: Add the server to ChatGPT

5. Step 5 of 7: Add the server to ChatGPT

   In shortIn ChatGPT on the web, open Plugins and add a custom MCP server. Check your plan first.

   OpenAI’s help page limits custom MCP servers by plan. Full use, with changes, is for Business, Enterprise and Edu. Pro users can connect them to read only. The page does not list Free or Plus.

   1. On ChatGPT on the web, go to Plugins.
   2. Select the plus button, then Add custom MCP server.
   3. Enter a name and the server’s public HTTPS address.
   4. Set up its sign-in, then tick I understand and want to continue under the risk warning.
   5. Select Create as a plugin, and review the tools it found.

   On a Business plan, only admins and owners can add one. You cannot add a server on a phone: it is web only. ChatGPT also connects to remote servers only. A server on your computer needs OpenAI’s Secure MCP Tunnel.

   To use it, type @ in a new chat and pick the plugin. Some servers are also in ChatGPT’s own list: Frooition’s page says to open Settings › Apps and search for it.

   	Claude	ChatGPT
   Where	Customize › Connectors › Add custom connector	Plugins › + › Add custom MCP server
   Plans	Free (one custom connector), Pro, Max, Team, Enterprise	Business, Enterprise and Edu. Pro reads only.
   Who adds it at work	An Owner, in Organization settings	An admin or owner. Enterprise and Edu can allow others.
   Changes	Asks you to approve tool use. A tool can be set to Blocked.	May ask you to confirm, based on the app’s permissions
   Server on your computer	Claude Desktop or Claude Code	Not directly. It needs OpenAI’s Secure MCP Tunnel.

   Result: The server added in ChatGPT, or a clear reason to use Claude instead.

   Mark this step as doneNext: Test with read-only questions first

6. Step 6 of 7: Test with read-only questions first

   In shortAsk questions you already know the answer to, then approve one small change by hand.

   Check the server before you trust it. Open eBay Seller Hub in another tab, then ask three questions it can answer:

   1. How many orders are waiting to ship?
   2. What is the price and quantity of one listing you know?
   3. Which buyer messages have no reply yet?

   Compare each answer with Seller Hub. If one is wrong, find out why before you allow any change.

   Then try one small change on one listing. Read what the AI is about to send before you approve it. Never approve a bulk change you have not read line by line.

   • In ClaudeReview each tool approval request. Anthropic says to click Always allow only for trusted servers. In Customize › Connectors, you can set a tool you do not need to Blocked.
   • In ChatGPTIt may ask you to confirm a change, based on the app’s permissions and what it is doing.
   • On the serverFrooition shows bulk changes, shipped orders and buyer replies before it acts. Its page says changes go live on eBay at once, with no undo.

   Result: Three answers that match Seller Hub, and one small change you approved and checked.

   Mark this step as doneNext: Remove access you no longer use

7. Step 7 of 7: Remove access you no longer use

   In shortRemove a server you stopped using in three places: eBay, your AI app and the service.

   A connection keeps its access until you remove it. eBay’s developer help gives the path on eBay:

   1. Sign in to eBay and open Account settings.
   2. Under Account, click Sign in and security.
   3. Find Third-party app access and select the app.
   4. Click Apply to remove it.

   Then remove the server from your AI app:

   • ClaudeIn Customize › Connectors, click Remove next to the connector.
   • ChatGPTIn Settings › Plugins, select it, open the ••• menu or Connection, and select Disconnect. OpenAI says this does not delete your past chats or saved memories.
   • The serviceA hosted server has its own page. Frooition’s is Account › Connected apps.
   • Your computerDelete the keys and tokens from the server’s config file.

   Remove access on eBay first, before you cancel anything else. Check this list once a month, as the best eBay seller tools guide suggests for every app.

   Result: Only the servers you still use have access to your eBay account.

Common questions about eBay MCP

How Productivo’s MCP server compares

In shortProductivo runs its own hosted MCP server over Productivo’s data. It is not eBay’s, and it edits no live titles.

Productivo (productivo.store) is an eBay seller app for US sellers that also runs a hosted MCP server for ChatGPT, Claude, Claude Code and Codex. The AI reads your store data in Productivo and, if you allow it, makes changes there.

It is Productivo’s own server, over the data Productivo keeps for your stores. It is not an eBay MCP server from eBay. Productivo connects to eBay through eBay’s consent page, and the AI app never gets your eBay login.

Point	Productivo
Who runs it, where	Productivo, hosted at api.productivo.store/mcp
Sign-in	OAuth 2.1 on Productivo’s own page. You choose Read only or Read and change, and which stores. No eBay developer keys.
AI apps it names	ChatGPT, Claude, Claude Code and Codex
Reads	19 tools: stores, listings and their traffic, products, competitors and price history, orders, profit reports, product scans, jobs, the seller guide and support cases. Buyer addresses are left out.
Changes	7 tools: add, approve, schedule or remove products, start a product scan, and open or reply to a support case. Removing a product ends its eBay listing. It does not edit a live listing’s title or price.
Price	Every plan, with an active subscription or trial: Starter $18.74, Basic $24.99, Pro $34.99, Scale from $44.99 a month. Listing traffic and product scans need Pro or Scale.
Last update	Last change to its tools: 19 October 2026

How it signs in: you paste https://api.productivo.store/mcp into your AI app. It sends you to Productivo to sign in and choose Read only or Read and change. Productivo refuses any change from a Read only connection. Billing, team, sign-in and admin pages stay out of reach.

How you remove it: open the profile menu, then AI connections, and click Disconnect. It stops at once. The account owner sees every connection, with who connected it and when it was last used. Team members connect their own, with their own access.

Plans: Starter is $18.74 a month, Basic $24.99, Pro $34.99 and Scale from $44.99. Every plan includes AI connections. A 7-day trial comes with a payment method.

Its product tools add Amazon products to your store. eBay does not allow buying an item from another retailer or marketplace after the sale, for delivery to your buyer. The eBay dropshipping policy guide explains what is allowed.

When another option fits better

• The AI should edit live listingsTitles, prices, item specifics or photos on eBay itself. Frooition for eBay or YosefHayim/ebay-mcp have those tools. Productivo’s do not.
• Buyers and shippingReplies to buyers, or marking orders shipped from the chat. Frooition’s page lists both.
• Raw eBay API accessYou build or test with eBay’s APIs. eBay’s own server is made for that.
• No paid planThe open-source servers and Frooition’s free plan cost nothing to start.
• Other AI appsProductivo names four AI apps. Frooition also names Grok, and YosefHayim’s sets up Cursor and Windsurf.
• eBay sites outside the USProductivo is built for US sellers on eBay.com.

One address, four AI apps

You copy the address into your AI app. The app then sends you to Productivo to sign in and choose what it may do.
