About this plugin
When building a project, launching a site, or running SEO research, confirming whether a batch of domain names is already registered is a recurring pain point. Checking each one manually on a registrar website is slow, and it quickly becomes unmanageable when the candidate list runs into the dozens or hundreds.
Built on Python and the MCP protocol, xby-fastdomaincheck focuses on batch querying: pass multiple domains into check_domains in a single call and receive a structured JSON result showing the registration status of each, with no repetitive round-trips. The API key set via set_xby_apikey is persisted automatically, so it survives session restarts and removes the friction of reconfiguring before every check.
Whether you are an indie developer brainstorming product names, a site administrator auditing competitor domains, or wiring a domain-availability step into a DeepSeek Harness automation pipeline, this lightweight web tool turns domain checking from a page-by-page chore into a one-line task.
Use Cases
- Quickly filter a batch of candidate domains when brainstorming a new product name
- Bulk-check whether competitor site domains are already taken
- Embed a domain-availability step into a DeepSeek Harness automation pipeline
Best For
- Indie developers brainstorming product names
- Site administrators managing domains at scale
