*Source: [https://www.selltostate.com/integrations/chatgpt/](https://www.selltostate.com/integrations/chatgpt/)*

Add Sell to State to ChatGPT as a custom MCP server. Then ask ChatGPT for tenders, buyers and contract awards. ChatGPT calls the Sell to State tools and shows the official links.

## What you can do

- Find tenders that still accept bids, with the deadline and the link to the official notice.
- Profile a public buyer: spend by year, sectors and top suppliers.
- See which public contracts a company won, by country and buyer.
- Find the companies that win contracts for a product or a service.
- Save a search and manage your lists in your Sell to State account.

## Set up

1. **Open the plugins page.** Go to chatgpt.com/plugins. Select the plus button, then Add custom MCP server.
2. **Add the Sell to State URL.** Name the server Sell to State, paste this URL and choose OAuth.

   ```
   https://app.selltostate.com/api/mcp
   ```
3. **Confirm and sign in.** Read the risk warning and confirm. Sign in to your Sell to State account and select Allow access.
4. **Ask a question.** Start a new chat, add Sell to State, and ask about tenders, buyers or suppliers.

## Ask ChatGPT

- "Find UK tenders for payroll software that still accept bids."
- "Who are the top suppliers of Countess of Chester Hospital NHS Foundation Trust?"
- "Which German public contracts did Rohde & Schwarz Cybersecurity win?"
- "Show open tenders in Ireland about cybersecurity from the last 30 days."
- "Which companies win government contracts for cybersecurity in Germany?"

## Requirements

- A ChatGPT plan and workspace settings that allow custom MCP servers.
- A Sell to State account with an active plan. The tools return data only for an active plan.
- Data depth differs by country. The countries page shows what each country has.

## Questions

**Do I need an API key?** No. The assistant signs you in to your Sell to State account with OAuth. You see a consent page that names the application and the address it returns to. The access token expires after 1 hour and renews for up to 30 days.

**Is Sell to State in the ChatGPT plugin directory?** Not yet. Until it is listed, add it as a custom MCP server with the steps on this page. The tools and the data are the same.

**Where does the data come from?** From official government procurement sources, for example Find a Tender and Contracts Finder (UK), TED (EU) and national portals. Each tender links to its official notice.
