What it is
The Opero3P connector is a Model Context Protocol (MCP) server at https://www.opero3p.com/mcp. Add it to Claude as a custom connector and Claude can read your Opero3P workspace through about 55 tools, each one scoped to your own workspace and your role in it.
📦 Inventory & profit
True landed cost per unit (FIFO), profit per ASIN, stock, restock timing, hold-or-sell for stock under break-even.
💲 Repricer
Buy Box and competitor history, why a price moved, Bob's pricing plans per listing, and (if you allow changes) setting strategies and limits.
📊 Money
Monthly P&L with Amazon fees by line, payouts, bank and card lines, goals and month-end close.
🧾 Back office
Reimbursements, short shipments, refunds with no return, the case log, and full report downloads for an audit.
✉️ Outreach
Brands, campaigns and replies; your Claude researches and writes each brand's first email and saves it as a draft.
🔎 Sourcing
Leads, gating (what you can sell and what just opened up), watched storefronts, and the Wholesale Finder skill.
Things you can ask
Answer brand replies with Claude
The Reply Assistant skill (included) works through the replies brands send to your wholesale outreach. Say "go through my brand replies" and Claude reads each one with the whole thread and what Opero knows about the brand, sorts what they want (open an account, price list, application, distributor only, no, unsubscribe), and writes the answer in your voice.
- Draft or send, your choice per email. Drafts land in Opero's Inbox tagged ✍️ Drafted by Claude. Sending goes from your own Gmail, in the same thread, one email per yes: Claude shows the exact email first.
- Brand updated for you: status (Replied, Won, Lost), handled, follow-up notes. Stop requests are never answered; the contact is marked unsubscribed.
- Facts only: Claude uses your business profile and Opero's data, and asks you when something is missing. It never writes your tax ID or bank details.
Set it up in 2 minutes
- In Claude: Settings → Connectors → Add custom connector. Name it Opero, URL
https://www.opero3p.com/mcp. - Click Connect and sign in to Opero3P. Pick the workspace.
- Optional: tick Also allow changes so Claude can save things. Every change shows a preview first and waits for your yes, and every change can be undone.
You need an Opero3P workspace where you're the owner or an admin (or a team role that allows it), and a Claude plan that supports custom connectors. Opero3P's own getting-started guide walks through it.
Works alongside your other connectors
Claude can use several connectors in one answer. Pair Opero3P with Keepa (price and seller history), SmartScout (brand and category market data) and FBA+ Academy (Seth Miller's ungating, sourcing and reimbursement protocols) and ask questions that need all of them, like "of the brands that just opened up for me, which have no Amazon on the listing and fewer than 10 sellers?"
Recording a screen share or a course video? Turn on Recording mode in Opero3P and your company, supplier and product names are swapped for stand-ins on screen and in what Claude sees; the numbers stay real.
Questions
Does Opero3P work with Claude?
Yes. Opero3P has its own Claude connector (an MCP server at https://www.opero3p.com/mcp). Add it in Claude under Settings → Connectors and Claude can answer questions using your Opero3P data.
Can Claude change my prices or anything else?
Only if you tick Also allow changes when you connect, and even then every change shows a preview and waits for your yes. Every change is logged and can be undone. Claude never acts in Amazon Seller Central.
Can Claude answer my brand emails?
Yes. With the Reply Assistant skill, Claude reads the replies brands sent to your outreach, writes each answer in your voice, and saves it as a draft or sends it from your Gmail in the same thread, one email at a time after your yes. Unsubscribe requests are never answered.
Does Claude see other sellers' data?
No. The connection is to one workspace, and every look-up is scoped to it and to your role.
Is the connector included?
Yes, for paying members and during the 14-day trial, at no extra cost. You need a Claude plan that supports custom connectors.
How do I disconnect?
In Opero3P: Settings → Connections → Claude connector → Disconnect. It stops working immediately.
