mcp-si-radar
Authoritative Registry Socket Scanner, Real-Time Availability Checker, GEMINI Rule 10 Evaluator & Instant Checkout Generator for .si (Slovenia) ccTLDs.
📌 Problem & Technical Architecture
1. Common Bottlenecks in .si Domain Acquisition
Registrar Search Lag: Web interfaces of major registrars (Dynadot, Spaceship, Namecheap) frequently hang, show infinite loading spinners, or rate-limit users when searching for
.sidomains because of multi-TLD suggestions, marketplace calls, and heavy frontend bundles.Anti-Bot Roadblocks: Aggressive Cloudflare Turnstile, CAPTCHAs, and session timeouts disrupt research and domain acquisition workflows.
Cart Flow Friction: Adding domains through a web search bar re-triggers redundant checks and upsell popups that slow down domain registration.
2. The mcp-si-radar Solution
Direct Socket Connection to ARNES Registry (Port 43):
Connects directly via raw TCP socket to
whois.register.si:43(the sovereign national registry of Slovenia).Blazing-fast response time (~50ms – 200ms).
100% real-time authoritative accuracy, bypassing all web proxies, CDN queues, and CAPTCHAs.
Pacing Delay Engine (Batch Scanning):
Automatically paces sequential queries (default 350ms) to ensure ARNES firewall never rate-limits or blocks your IP.
Fast Checkout Deep-Links:
Generates clean direct URLs that open registrars with the target domain pre-selected and an immediate "Add to Cart" button, bypassing homepage search lag.
Automated Headless API Registration:
Direct integration with Dynadot REST API (
api.dynadot.com/api3.json) for zero-click purchases right from the AI chat window.
GEMINI Rule 10 Discipline ("Two-Reading Rule"):
Automatically scores Reading A (Domestic Slovenian Real-Economy Baseline) and Reading B (Superintelligence Option Value).
Delivers actionable verdicts: 🟢 HOLD (ACQUIRE), 🟡 OPTIONAL (SPECULATIVE), or 🔴 AVOID (HIGH RISK) to prevent portfolio dilution.

Scored across 5 tools
si_batch_check vs si_check_domain are clearly distinguishable (batch vs single), but si_check_domain's description says it also returns checkout links and Rule 10 evaluation, making it a superset that overlaps with si_fast_checkout and si_evaluate_rule10. An agent would struggle to know when to call the specialized tools versus just using si_check_domain.
All tools share a consistent si_ prefix and snake_case, with predictable verb/noun components (check, batch_check, fast_checkout, api_register, evaluate_rule10). Minor deviation in ordering (noun_verb vs verb_noun) but still readable and coherent.
Five tools is well-scoped for a specialized .si domain availability and registration workflow. Each tool earns its place across checking, batch scanning, evaluation, checkout linking, and registration.
Covers the full lifecycle of find-check-evaluate-buy with single check, batch check, Rule 10 evaluation, checkout deep-links, and automated API registration. Minor gap: no post-registration management (renewal, transfer, DNS) or bulk registration.
