What additional eMAG Marketplace tasks should Vendwiser handle through Claude or ChatGPT?
About Vendwiser
Vendwiser is an MCP connector for marketplace sellers. It links your eMAG Marketplace seller account and your Oblio invoicing account to the AI assistant you already use, so the daily seller work happens in a conversation.
Reading is immediate: orders, offers, stock, prices, returns, campaigns and invoices come straight from your accounts. Ask which orders are past their handover deadline, why an offer was rejected, or which products lost the buy button.
Changes are never applied directly. When the assistant proposes a new price, a stock update, an invoice, a shipping label or a campaign entry, Vendwiser simulates it and shows a before-and-after preview. Nothing reaches the marketplace until you approve it in the chat.
What else is in the box: - Order to invoice in one request: the Oblio invoice is built from the eMAG order and attached to it. - Protection rules that block risky changes, such as a price drop above your limit. - Scheduled agents and alerts that only read, and email you when something needs attention. - An activity log of every call and every approval.
Credentials are stored encrypted and are never shown to the assistant. Free plan with 15 tool calls a month; paid plans from EUR 49.
Works today with eMAG Romania and Oblio, from Claude and ChatGPT. Vendwiser is independent and not affiliated with eMAG or Oblio.
How it was built with Claude
Almost all of it was built in conversation with Claude: the MCP server, the OAuth 2.1 flow with dynamic client registration, the channel adapters for eMAG and Oblio, the dashboard and the tests.
What worked:
- Every write tool only simulates. It returns a preview and an action id, and a separate tool carries it out after the seller approves. That one rule made the whole product safe to test on a real shop.
- A sandbox per channel, so the end-to-end tests run against a simulated eMAG and Oblio instead of real accounts.
- Three small router tools (search, schema, run) so clients with a stale tool list still reach new tools without reconnecting.
- Testing each tool from Claude and ChatGPT on a real seller account, and fixing what the assistant misunderstood in the tool descriptions.
No framework and no dependencies: plain Node.js.
