Model Context Protocol
Run your reselling from Claude or ChatGPT.
Prelo is a remote MCP server. Point your assistant at a folder of photos and it uploads them, creates the items, and drafts the title, description and price for each one. You approve the connection once. There are no API keys and nothing to install.
Server URL
https://www.listprelo.com/mcpAdd it as a remote connector in your assistant. Authentication is OAuth, handled in the browser.
Included with Pro.
Connecting it
The same three steps in any client, because the server is remote and the handshake is standard.
- 1Add the URLIn your assistant's connector settings, add https://www.listprelo.com/mcp as a remote MCP server.
- 2Approve onceYour browser opens, you sign in to Prelo and approve. The assistant never sees a password.
- 3Ask for somethingTry "what’s in my Prelo account" to check it, then point it at a folder of photos.
What it can do
| Tool | What it does |
|---|---|
| prelo_whoami | Confirms the connection and reports the account, plan and remaining credits. |
| prelo_list_items | Lists your items, most recent first, optionally filtered by status. |
| prelo_get_item | Full detail for one item: title, description, price, condition, SKU, status, photo count. |
| prelo_start_photo_upload | The fast path for photos on disk. Creates a draft and returns a presigned upload URL per file. |
| prelo_finish_photo_upload | Confirms the files landed, attaches them to the draft and marks it ready. |
| prelo_upload_photos | The slow path, for one or two images already pasted into the conversation. |
| prelo_create_listing | Runs Prelo’s AI over an item’s photos to draft a title, description, price and condition. |
| prelo_update_item | Edits an existing item’s title, description, price or condition. |
| prelo_refresh_listing | Rewrites a title and description in a chosen style: concise, detailed, SEO, friendly, or matching your own. |
| prelo_set_inventory_sku | Tags an item with a SKU and marks it stored, for inventory you track by code. |
| prelo_crosslist | Prepares an item for other marketplaces and queues it for the browser extension. Nothing goes live without you. |
What it deliberately does not do
- Publish to eBay
- Drafts are saved to Prelo for you to review and publish from the web app. An assistant never puts a listing live on your account.
- Work without a Pro plan
- The server checks your plan on every call and refuses anything below Pro. Complimentary Pro access counts.
- Run for free
- prelo_create_listing consumes one listing credit, the same as creating a listing in the app. Rewrites draw on your plan’s monthly refresh allowance.
- Need an API key
- Connection is OAuth. You approve it once in your assistant and can revoke it from Prelo at any time. No key to paste, store or leak.
- Put a listing live anywhere
- It can prepare and queue a cross-list, but nothing publishes on its own. eBay and Etsy hand off to their own publish flow in the web app. Poshmark, Mercari, Depop and Vinted are queued for the browser extension, which opens each pre-filled form the next time Chrome is running and waits for you to press Submit.
- Cross-list without your browser
- Queued work waits for your browser. If Chrome is shut, it sits until you open it. An assistant should tell you something is queued, never that it is listed.
Questions
- Which assistants work with it?
- Anything that speaks MCP over HTTP with OAuth. Claude and ChatGPT both do. Add it as a remote connector using the URL above; there is nothing to install locally.
- Is this a local server I have to run?
- No. It is hosted, so there is no config file to edit, no Node process to keep alive and no path to get wrong. You add a URL and approve the connection.
- Can it list my item everywhere?
- It can set everything up in one step and queue the work, but every path still ends with you confirming in a browser. That is deliberate: an assistant should not be able to put listings on your marketplace accounts unattended.
- What can it actually see?
- Your Prelo items and account, nothing else. It has no access to your eBay password, your payment details, or any marketplace account.
- How do I revoke it?
- From Settings in Prelo. Revoking stops every future call immediately.
- Does it upload the photos through the model?
- No, and that matters for speed. For files on disk it hands back a presigned URL so the bytes go straight to storage. Base64 through a model call is slow and only used for an image already sitting in the conversation.
- What happens to a draft it creates?
- It appears in your Items list like any other draft, with the photos attached and the AI fields filled in, ready for you to check and publish.
Photos in, drafts out, without opening the app
Included with Pro, alongside 600 AI listings a month, cross-listing, warehouse tracking and the rest.
