How to connect ChatGPT to public records

ChatGPT supports custom MCP connectors, so you can point it at Amalgament and it gains tools to query US public records live. The setup is the same single connector URL every MCP client uses; ChatGPT handles the rest.

1. Open ChatGPT's connector settings

In ChatGPT, open Settings and find the connectors area where custom MCP servers are added. Amalgament is a remote MCP server, added by URL.

2. Add Amalgament by URL

Add a custom connector with the server URL: https://api.amalgament.com/mcp. There is no separate key; the URL is the whole configuration.

{
  "mcpServers": {
    "amalgament": {
      "url": "https://api.amalgament.com/mcp"
    }
  }
}

3. Authorize once

Approve access when ChatGPT prompts you on first use. The Amalgament tools then appear and your 500 free credits are ready.

4. Ask a question

Ask in plain language. ChatGPT picks the right Amalgament tool and pulls the records to answer, mid-conversation.

Try asking

• What public records exist for Brooklyn Brewery?
• Who owns the parcel at 4510 W Lake St, Chicago?
• Show UCC liens filed against Acme Roofing LLC.
• What has the federal government paid this vendor?

Common questions

Do I need an API key to use Amalgament in ChatGPT?

No. The Amalgament MCP server uses sign-in (OAuth): the first time ChatGPT calls it, you authorize once in-app and the tools stay connected. A separate REST API key exists if you also want to call Amalgament from your own code.

Is it free?

Every account starts with 500 free credits. After that, one-time credit packs (Starter $29, Growth $99, Scale $299), and you are only charged for successful calls that return data.

Which tools does ChatGPT get?

Seven: search_records, records_at_address, records_at_parcel, records_for_entity, get_canonical_entity, get_record, and list_datasets. The agent discovers them automatically and calls the right one for your question.
