Name: Domain Radar
Author: insight

Domain Radar is a production-grade Model Context Protocol (MCP) server powered by insight.surf. Built for domain investors, founders, and autonomous AI research agents, it performs authoritative multi-TLD RDAP registry auditing, keyword combination generation, and real-time live website activity probing.

Core Capabilities

1,200+ Global TLD Dynamic IANA Bootstrap: Queries authoritative registries across over 1,200 top-level domains (.com, .net, .org, .ai, .io, .xyz, .tech, .app, .cloud, .co, .de, etc.).
Live Activity Radar (In-Use vs Inactive/Parked): Probes registered domains in real-time via DNS and HTTP/HTTPS to classify them into:
- 🟢 UNREGISTERED: Not found in registry at audit time (available to register).
- 🔵 ACTIVE_IN_USE: Actively operating website/service (proof of commercial adoption).
- ⚪ INACTIVE_OR_PARKED: Registered but dormant (no DNS) or parked on domain aftermarket marketplaces (Dan, Sedo, HugeDomains, Afternic).
Flexible Keyword Positioning: Generate combinations with keyword as prefix (kw+word), suffix (word+kw), or inside (mod+kw+word).
Hyphen & Numeric Pattern Controls:
- Hyphen: none (unhyphenated), hyphen_only (hyphenated), or both.
- Numbers: none (letters only), include (with high-value commercial patterns like 24, 365, 360, 247, 101, 88), or numbers_only.
Autonomous Agent-Ready (readOnlyHint: true): Properly encapsulated in the official MCP annotations object so AI clients (Claude Desktop, Cursor) execute automated research loops without permission prompts.
Polite Rate Limiting & Zero API Keys: Batch-throttled to avoid HTTP 429 rate limits. Runs locally via stdio at $0 operational cost.

Tools Included

search_keyword_domains: Full DotDB-equivalent search engine. Supports keyword positioning (beginning, end, any), character filters (include_alphabets, include_digits, include_hyphens), live site status probing (active, parked, inactive, unregistered), and custom TLD lists across 1,200+ IANA extensions.
scan_keyword_tlds: Audits exact keyword registration coverage across 1,200+ authoritative TLDs and probes real-time web activity.
search_keyword_combinations & find_available_combinations: Backward-compatible aliases for legacy workflows.
