RealtimeRegister MCP Server & Client

A Node.js library and Model Context Protocol (MCP) server for interacting with the RealtimeRegister API for domain management operations.

Overview

This package provides a robust client for the RealtimeRegister API and an MCP-compliant server, enabling applications and AI assistants to:

• Check domain name availability.
• Test API connectivity.
• Perform other domain-related operations (future).

It features a caching layer for performance, typed responses, and comprehensive error handling.

Features

• RealtimeRegister API Client: Strongly-typed client for core API functions.
• Caching Layer: Built-in LRU caching for checkDomainAvailability and other requests to reduce API calls and improve response times.
• MCP Server: Exposes functionality via the Model Context Protocol for integration with MCP-compatible systems.
• Environment Configuration: Easy setup using environment variables.
• Error Handling: Custom error types for API and network issues.
• TypeScript Support: Written in TypeScript with declaration files for a better development experience.

Prerequisites

• Node.js 18.0.0 or higher / or Docker
• RealtimeRegister API key (for most functionality)
