How to integrate Domainsdb.info using MCP
Search registered domain records. This guide creates an MCP server from Arthur's Domainsdb.info template — tools preconfigured against https://api.domainsdb.info/v1 — and finishes by sharing the server's MCP swagger documentation.
Steps
Open the Secrets vault and create a secret named
DOMAINSDB_API_KEYholding your access token. Register at domainsdb.info to obtain an API key, then send it as an Authorization: Bearerheader. 


Go to the REST API Templates gallery and search for Domainsdb.info.


Click Use template on the Domainsdb.info card to open the server-creation dialog.


Review the server name and select
DOMAINSDB_API_KEYin the credential field — the dialog only accepts vault secrets, and it lists every tool that will be created.


Click Create server. Arthur creates the server, applies the authentication, and generates all the tools.





Open the server's Tools tab to review the generated tools.

Open the server's Connect section and click Share the MCP swagger documentation — Arthur generates the public documentation link and QR code for this server.



Confirm it worked
The server appears with 2 preconfigured tool(s): search_domains, search_tld_domains. The Connect section offers the MCP swagger documentation — a shareable page with setup instructions for any AI client.
Good to know
- Search the registered-domain database by name, zone, country, or DNS record values, and search domains within a specific top-level domain zone.
- This integration requires a credential (bearer). Get one at https://domainsdb.info/.
- Official API documentation: https://domainsdb.info/docs
- Editing a tool later never changes the template — templates are starting points, and the server is fully yours after creation.
