MCP connector

Connect Claude & ChatGPT to Your Inventory

Inventory Inventory is an MCP server. Add it as a connector in Claude, ChatGPT, Cursor or any MCP-capable assistant, sign in with Google, and ask about your live stock in plain language — or record a sale — without leaving the chat.

  • One URL to connect: https://inventoryinventory.com/api/mcp
  • Sign in with Google and approve — no API key to paste
  • Ask “what is running low?” or “what expires this month?” in Claude or ChatGPT
  • Record sales from chat; the assistant confirms before deducting

What MCP is, and why it matters for stock

The Model Context Protocol (MCP) is the open standard AI assistants use to plug into outside systems. A product exposes a small set of tools; the assistant discovers them and calls them on your behalf. Claude, ChatGPT, Cursor, Copilot-style agents and most agent frameworks speak it. Inventory Inventory publishes an MCP server, so your inventory becomes something your assistant can look at and act on.

In practice: you open your assistant's connector settings, paste the server URL, and a sign-in window from inventoryinventory.com appears. You approve read access, and optionally the ability to record sales. From then on, “how many iPhone 14 screens do we have?”, “list everything below its reorder level”, “what expires before Christmas?” and “we just sold three of the blue mugs” are answered from live data, and a sale posted from chat is logged, deducts the soonest-expiring batch first, and triggers alerts, auto-reorder and Square or Shopify sync like any other sale.

Security is built on OAuth 2.1, the same mechanism banks and Google use for third-party access: short-lived tokens that expire in an hour, refresh tokens that rotate on every use, a consent screen that names the app and what it may do, and a Connected AI apps list on your profile where any connection can be revoked in one click. The assistant only ever sees items you marked “Include in API”. No AI runs on our side — the model is the one you already pay for.

What you get

Ask, don't click

Stock questions get answered in the chat you already have open, from live numbers.

Six focused tools

List inventory, get an item, low stock, expiring soon, inventory summary, record a sale. Small on purpose, so it costs few tokens and confuses nothing.

Sales from chat, safely

record_sale is flagged destructive, so assistants confirm first. Never below zero, FEFO on batches, always logged.

OAuth, not keys

Google sign-in and a consent screen. Tokens expire and rotate. Revoke any app from your profile.

Only what you expose

Per-item “Include in API” controls what any assistant can see — the same rule as the REST API.

Works everywhere MCP does

Claude web and desktop, Claude Code, ChatGPT, Cursor, and agents you build yourself.

Your stock, one question away

The best inventory interface is the one you are already typing into. MCP puts a trustworthy stock number inside every assistant your team uses.

How it works

1

Add the connector

In your assistant's settings, add a custom MCP connector with https://inventoryinventory.com/api/mcp.

2

Sign in and approve

A window from inventoryinventory.com asks you to sign in with Google and approve read access, and optionally recording sales.

3

Ask away

Low stock, expiries, values, a specific SKU — or record a sale. Revoke from Profile → Connected AI apps whenever you like.

Frequently asked questions

How do I connect Claude to my inventory?

In Claude, open Settings, then Connectors, and add a custom connector with the URL https://inventoryinventory.com/api/mcp. Claude opens a sign-in window from inventoryinventory.com; sign in with Google, approve the access you want, and the tools appear in your chat. In Claude Code, run: claude mcp add --transport http inventory-inventory https://inventoryinventory.com/api/mcp, then /mcp to sign in.

Does it work with ChatGPT?

Yes. ChatGPT supports remote MCP connectors: in Settings, open Connectors, create one with the same server URL, and complete the sign-in. The same six tools are available, and sales recorded from ChatGPT are logged as coming from ChatGPT.

What can an assistant do once connected?

Read the items you marked “Include in API” — quantities, prices, cost prices, suppliers, reorder levels, expiry batches and locations — and, if you approved it, record sales. It cannot create, rename or reprice items, change settings, or see anything you did not expose. Every sale it records appears in your activity log attributed to the app.

Is it safe to give an AI access to my inventory?

Access uses OAuth 2.1 with PKCE, the standard that Google and the major banks use for third-party apps. You approve on a consent screen that names the app and its return address; tokens expire in an hour and refresh tokens rotate on every use; any connection can be revoked from your profile in one click. The write tool asks the assistant to confirm with you before it runs, and it can never take stock below zero.

Does this use my Inventory Inventory AI features?

No AI runs on our side for MCP. The model is the Claude or ChatGPT you already use, and their usage rules apply. Our server simply answers the tool calls from your live data.

Which plan do I need?

MCP access is part of the Pro plan at $10 per month, alongside the AI features, imports, purchasing, the store integrations and the REST API. Free accounts can connect but tool calls are declined with an upgrade link.
