About
DomainCheckr is a hosted MCP server that checks domain-name availability via RDAP, supporting single lookups, bulk checks and smart name suggestions, with no API key required. A solo builder reaches for it when naming a new project to quickly see which domains are free before committing. It pairs naturally with a registrar when it is time to buy.
