Intelligent domain name suggestion service that checks real-time availability across multiple providers and works with MCP-compatible tools like Cursor and Claude Code.

Enables fast, token-efficient bulk domain name search for AI agents, checking up to 1,000 domains per request to see availability statuses.

A throwaway HTTP MCP server that empirically tests whether Cursor invokes tools by exact name or munges them, to inform case normalization decisions.

Enables checking domain availability using WHOIS and DNS resolution, with support for single and batch queries.

Enables domain availability checking through dual verification using WHOIS lookups and DNS resolution. Supports both single and batch processing to provide detailed analysis on whether domains are likely available or already registered.
