3Dsellers MCP

3Dsellers' hosted MCP server connects your agent to your 3Dsellers account, the multichannel selling platform built for eBay sellers. 3Dsellers keeps one product catalog for every channel you sell on, so your agent can create products, publish listings to eBay, Amazon, Walmart, Etsy, Shopify and TikTok Shop, keep stock and prices in line, handle orders and answer buyers. It all runs through 3Dsellers, so there's no eBay developer account or marketplace API key to set up. What you can do with it - Search, create and edit products in your catalog, with variations, images and identifiers - Publish products to eBay and your other channels, and set item specifics, business policies and eBay store categories - Set quantities on listings and variations, and turn inventory sync on or off - Find orders, tag them, add tracking and create invoices - Change prices, item specifics, policies or tags across many listings in one bulk action - Import supplier CSV files with a dry run first, and schedule imports and exports - Read and answer Helpdesk tickets from buyers, and set up automatic post-sale messages - Set up automations, automatic offers to watchers and listing description templates How it connects 3Dsellers hosts it at https://api.3dsellers.com/mcp. Chat agents such as ChatGPT and Claude sign you in with your 3Dsellers account, with no token to copy. Coding agents can use a bearer token instead: in 3Dsellers, open Settings > Profile > API / MCP, click Connect MCP and generate a token under For developers, then send it as an Authorization: Bearer header. The token is shown only once. Good to know - You need a 3Dsellers account on a plan or the free trial, with your selling accounts already connected to it. - Tools that change data ask for your approval before they run. - Tokens can be scoped, for example product:read to only read products. Every call is logged on the API / MCP page, and you can revoke one token or all of them. - Reading your data is free. Actions the AI runs use AI actions bought in advance. - 3Dsellers makes and hosts this server; it isn't an eBay product.
