Fastdomaincheck is a domain availability check server built with Python and the Model Context Protocol (MCP). It provides MCP tools to check whether single or multiple domain names are already registered, using WHOIS and DNS dual verification.
Install and configure Fastdomaincheck by adding it to your MCP client's server configuration (e.g., Claude Desktop) using the uvx command and the package fastdomaincheck-mcp-server. Invoke the check_domains tool with a JSON object containing an array of up to 50 domain names.
It returns an object mapping each domain to a `registered` boolean: `true` means registered, `false` means available.
Yes: each domain name must be 255 characters or fewer, you can send up to 50 domains per request, and no empty domain names are allowed.
The tool will return an error message in JSON format, for example if the domains list is empty, exceeds 50 domains, or contains an empty name.
Yes, IDN support is listed as a feature.
It is installed via `uvx` using the package name `fastdomaincheck-mcp-server`, configured in your MCP client’s settings file (e.g., `claude-desktop-config.json`).
