Model Context Protocol

Manage OnBuy from your AI assistant

The Re-Pricer MCP server lets Claude and other AI tools work directly with your OnBuy listings — check the Buy Box, review prices and reprice by SKU, all through a secure connection you control.

Connect for free — your assistant can read your listings, prices and Buy Box status at no cost. Repricing by chat is included with any Re-Pricer plan.

In plain terms

What is the Re-Pricer MCP?

MCP (Model Context Protocol) is the open standard AI assistants use to securely connect to the tools you already use. The Re-Pricer MCP server exposes your OnBuy repricing account to any MCP client — so instead of clicking through dashboards, you simply ask. Pricing safety rules you've already set are always respected.

Tools

What your assistant can do

Five purpose-built tools, scoped to your account. Read tools are free; repricing is included with any plan.

list_listings

Read-only

Search and list your OnBuy listings by SKU or product code, with price, stock and status.

check_winning

Read-only

Check whether you're winning the Buy Box for any SKUs and see the lowest competing price.

update_listing_prices

Writes prices

Update live listing prices by SKU. Prices outside your configured min/max are blocked automatically.

list_categories

Browse OnBuy marketplace categories with their ids and category fees.

get_commission_tiers

Read-only

Look up OnBuy commission tiers — the fee bands used to calculate your costs.

Setup

Connect in three steps

No keys to copy. No code to write.

  1. 01

    Add the connector

    In Claude (or any MCP client), add a custom connector pointing at your Re-Pricer MCP URL.

  2. 02

    Connect securely

    Sign in to your Re-Pricer account and approve access. We use OAuth 2.1 — no API keys are ever copied or pasted.

  3. 03

    Start asking

    Ask your assistant to check Buy Box status, review prices, or reprice a SKU — all within your safety limits.

Safety

Secure by design

You stay in control of your account and your prices.

OAuth 2.1, not API keys

Connect with a one-click secure login. Your OnBuy credentials stay encrypted in Re-Pricer and are never exposed to the AI.

Min/max price guardrails

Every price change is checked against the minimum and maximum you've set per product. Out-of-bounds prices are rejected before they ever reach OnBuy.

Scoped to your account

Each connection only ever sees and changes your own listings — nothing else.
