Amalgament ships as an MCP server, so Claude can query US public records directly: business filings, property, liens, permits, licenses, and government spending, resolved into one graph. You add it once as a custom connector and Claude gains the tools. Here is the whole setup.
In Claude, go to Settings and find the Connectors area (custom or remote MCP servers). Amalgament is a remote MCP server, so you add it by URL rather than installing anything locally.
Add a custom connector and paste the server URL: https://api.amalgament.com/mcp. That single URL is the whole configuration; there is no key to paste and nothing to run.

}The first time Claude uses Amalgament it prompts you to sign in and approve access. Authorize it, and the Amalgament tools appear in the conversation. Your 500 free credits are already on the account.
Now just ask. Claude reads the tool descriptions and calls the right one, so you can ask in plain language and it pulls the records to answer.

No. The Amalgament MCP server uses sign-in (OAuth): the first time Claude 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.
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.
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.
