Hosted 3Dsellers MCP vs a Local Open-Source Server
Some eBay MCP servers on GitHub run on your own computer and talk to the eBay API directly. Here is how the hosted 3Dsellers server compares.
3Dsellers MCP
Get Started FreeOpen-Source eBay MCP
Pricing
The MCP server is included in every 3Dsellers plan, including the free trial. Actions the AI runs use AI actions that you buy in advance: AI Lite, 2,000 actions for $9 a month; AI Pro, 5,000 actions for $20 a month; AI Elite, 10,000 actions for $29 a month. Reading your data, such as listing orders or searching products, is free.
Manage Tokens, Permissions and Requests
Every AI assistant and integration connects to 3Dsellers with a token. The API / MCP page in Settings shows every token, what it is allowed to do, every call it made, and how much of your rate limit is left.
Connect and create tokens
Open Settings > Profile > API / MCP, or go to app.3dsellers.com/api-mcp. Add to Claude connects Claude with a sign-in and no token to copy. Get API token creates a bearer token for your own script or integration. Connect MCP shows the server URL and a token for developer tools such as Cursor, VS Code and Claude Code.
A token is shown only once, when it is created. Copy it right away and keep it private.
See what each token is allowed to do
The Issued tokens list shows every token with its app, scope, status, request count, last use and expiry. The scope is the permission: product:read can only read products, product:write can change them, and Full access means every tool.
Revoke stops one token on its next request. Revoke all cuts off every app and AI agent at once; use it if a token leaked.
Review every call the AI made
The Requests tab logs every REST API call and every MCP tool call: time, source, tool name, status, duration and the error message when a call failed. Filter by token, source, status or date, and click a row for the full details.
Values that look like secrets are shown as [redacted], and only people in your 3Dsellers company can see the log.
Watch your rate limits
The Rate limits tab shows each limit, how much of it you used this minute and today, and when it resets. REST and MCP calls share the same counters: on a paid plan, 600 calls a minute and 50,000 a day for all tools combined, with separate limits for order and product reads and writes.
Per-minute counters reset every 60 seconds, per-day counters at 00:00 UTC.

3Dsellers Gives You the Tools You Need to Take Your eCommerce Business to the Next Level
The 3Dsellers MCP server is built for sellers who would rather ask than click. Connect it to Claude or ChatGPT in two minutes, then ask what sold today, which eBay listings have errors, or which products are low on stock, and let the assistant fix listings, update inventory, tag orders and publish products through your own 3Dsellers account. Every action runs with your approval and your data stays in 3Dsellers.
- Connect Claude, ChatGPT, Cursor or Claude Code to 3Dsellers with one sign-in or one server URL: https://api.3dsellers.com/mcp.
- Ask in plain language to search, create, edit and publish eBay, Amazon, Walmart, Etsy and Shopify listings.
- Let the assistant update inventory and prices, tag and ship orders, run CSV imports, answer Helpdesk tickets and queue bulk actions, with your approval before every change.

Manage Your Entire Product Catalog from One Place
3Dsellers keeps all your products and listings from every channel in one catalog. Through the MCP server the AI searches that catalog by SKU, title, tag or segment, creates products with variations, images and identifiers, and updates any field without touching the rest. One request can cover hundreds of products instead of one screen at a time.
%20(1).webp)
Ask the assistant to take products from your eBay store and publish them to Amazon, Walmart, Etsy, Shopify or TikTok Shop through 3Dsellers. It reads the fields each channel needs, fills in what is missing, sends the publish job and tracks it until it finishes, so new channels do not mean rebuilding every listing by hand.
.webp)
Monitor and Sync Your Inventory in Real Time Across All Channels
Ask which products are low on stock, set the quantity on a listing or a variation, or turn inventory sync on for an account, and 3Dsellers pushes the change to every connected channel. Daily stock checks become a question, and overselling on eBay or Amazon becomes much less likely.
Synchronize Pricing Across All Your Selling Channels
Ask the assistant to compare prices across your listings, find products priced differently on different channels, and raise or lower prices on a whole segment at once. You approve the change and 3Dsellers sends it to every marketplace.
.webp)
Enhance your Product Data with Custom Product Attributes
Ask which products are low on stock, set the quantity on a listing or a variation, or turn inventory sync on for an account, and 3Dsellers pushes the change to every connected channel. Daily stock checks become a question, and overselling on eBay or Amazon becomes much less likely.
Ask the assistant to find listings with missing item specifics, fill in brand, MPN, color or size across many products in one bulk action, and keep custom attributes consistent. Complete product data helps listings rank in eBay and Amazon search and gives buyers what they need to decide.
.webp)
Tailor Products to Each Selling Channel with Custom Channel Mapping
Each marketplace expects product data in its own format. The MCP server exposes the fields every channel category accepts, your mapping templates and your custom attributes, so the assistant can map product attributes to each channel, validate a template and apply field mappings across categories before you publish.
Quickly Assign Products to Categories on Each Channel with the Smart Category Mapper
Ask the assistant to list catalog categories that have no channel category yet, suggest the right eBay or Amazon category for each one, and set the mappings in bulk. Correct categories make products easier to find on every channel and unlock the right item specifics.

It is a hosted connection that lets an AI assistant such as Claude or ChatGPT work inside your 3Dsellers account: search and create products, publish listings to eBay and your other channels, update inventory and prices, manage orders and answer buyers. You connect it once with the server URL https://api.3dsellers.com/mcp and sign in. No code and no eBay developer account.
Yes, once ChatGPT is connected to 3Dsellers through the MCP server. Add 3Dsellers as an app in ChatGPT with the server URL, sign in, and ask it to create and publish a listing. ChatGPT drafts the listing, shows it to you, and publishes it to eBay through 3Dsellers after you approve.
Yes. 3Dsellers is listed in Claude's connector directory. Add it, sign in, and ask Claude to create a product and publish it to your eBay store. Claude shows the draft and asks for your approval before it publishes.
No. 3Dsellers is already connected to your eBay account, so the AI works through 3Dsellers. There is nothing to install, no API keys to manage and no developer application to apply for.
Open Claude's connector directory, add 3Dsellers, sign in to your 3Dsellers account and approve access. Then turn the connector on in a chat from the + menu. It takes about two minutes. Full steps are on the Claude page.
In ChatGPT, add a new app, paste https://api.3dsellers.com/mcp as the server URL, choose OAuth, sign in with your 3Dsellers account and click Accept. Then pick 3Dsellers from the + menu in any chat. Full steps are on the ChatGPT page.

Every token, its scope and every call it made are listed under Settings > API / MCP, where you can revoke it at any time.
