Model Context Protocol
regfish MCP server
Domains, DNS and web hosting as a toolbox for AI agents: secure, role-based, production-ready.
Endpoint
https://api.regfish.com/mcpContract v1.3.0
Authentication
API keys with roles (RBAC)
The MCP server uses regfish API keys. Every request authenticates via bearer token (or the x-api-key header); the key’s permissions determine which tools an agent sees and may use.
- 1Create a key in the regfish dash under Settings → Security → API keys.
- 2Pick a role when creating it, e.g. "DNS administrator" or "read only".
- 3Configure the complete key as the bearer token in your MCP client. It has the form keyid=secret; the = is part of the key.
Recommendation: always create a dedicated key with minimal permissions for each agent (least privilege). Never hand out your full-access key.
Authentication
Permissions
A key without a role assignment behaves as before (full access). With permissions set, the agent only sees the allowed tools. A read-only key is never offered write tools in the first place.

Configurazione
Un comando e funziona
Per Claude Code c’è il plugin regfish: una sola installazione e hai connessione, strumenti e competenza operativa. Usi un altro client MCP? Configura il server manualmente — trovi entrambe le strade qui sotto.
Server MCP
La connessione a regfish. Fornisce i 29 strumenti (leggere domini e hosting, modificare record DNS, diagnosticare) e verifica i permessi della tua chiave API a ogni chiamata.
Senza di esso Claude non può fare nulla con i tuoi domini.
Skill
Competenza operativa in forma di testo. Dice a Claude COME usare gli strumenti: prima leggere, poi modificare, poi verificare — e dove sono le insidie (un solo record SPF per dominio, abbassare il TTL prima di un cambio, l’ordine in DNSSEC).
Senza di essa Claude ha gli strumenti ma nessun criterio per usarli.
Plugin
Il pacchetto che porta entrambi e li mantiene versionati. All’installazione Claude chiede la tua chiave API e la salva nel portachiavi di sistema.
Senza plugin configuri server e skill separatamente — funziona anche così, è solo più lavoro manuale.
ConsigliatoInstalla il plugin (Claude Code)
Due righe, poi Claude chiede la chiave API. La chiave finisce nel portachiavi di sistema, non in un file di configurazione.
- 1Aggiungi il marketplace e installa il plugin (comandi a destra).
- 2Claude chiede la chiave API — incolla la chiave completa dal pannello.
- 3Fatto. Prova con: «elenca le mie zone DNS».
# in Claude Code
/plugin marketplace add regfish/claude-plugin
/plugin install regfish@regfish# oder im Terminal
claude plugin marketplace add regfish/claude-plugin
claude plugin install regfish@regfishLe due vie fanno la stessa cosa: usa quella da terminale se il tuo client non offre i comandi /plugin. Aggiorna con claude plugin update regfish, rimuovi con claude plugin uninstall regfish.
Solo lo skill
Utile se hai già il server MCP o lo vuoi senza plugin — uno skill è un singolo file di testo e funziona da solo.
- 1Esegui il comando qui sotto: mette i tre skill direttamente in ~/.claude/skills/.
- 2Riavvia Claude Code.
- 3Fatto. Gli skill si attivano automaticamente quando si parla di DNS, diagnosi o hosting.
S=https://raw.githubusercontent.com/regfish/claude-plugin/main/plugins/regfish/skills
for s in dns domain-check hosting; do
mkdir -p ~/.claude/skills/regfish-$s
curl -sL $S/$s/SKILL.md -o ~/.claude/skills/regfish-$s/SKILL.md
doneTre skill: dns (modifiche in sicurezza), domain-check (leggere una diagnosi) e hosting (collegare pacchetto e DNS).
Solo il server MCP (qualsiasi altro client)
Per client senza supporto ai plugin. Il server parla HTTP in streaming e si autentica con la tua chiave API regfish come bearer token.

"regfish": {
"type": "http",
"url": "https://api.regfish.com/mcp",
"headers": {
"Authorization": "Bearer <dein-api-key>"

}
}Questa variante non include la competenza degli skill. Per modifiche delicate vale la pena aggiungerlo.
Da dove iniziare
Frasi che funzionano appena la connessione è attiva:
- Elenca le mie zone DNS.
- Crea un record A per staging.example.com verso 203.0.113.10.
- Perché la posta di example.com finisce nello spam?
- Il mio cambio di nameserver è già propagato ovunque?
- Verifica se DNSSEC è davvero attivo per example.com.
- Su quale pacchetto di hosting gira example.com?
Tools
Tool catalog
All tools of the current contract (tool descriptions are delivered in German). Write tools act immediately on production DNS or the registry. Agents should read the current state before changing it and verify afterwards. The diagnostic tools (diagnose_domain, check_*) are powered by DNS Doctor (dns-doctor.com) and labeled accordingly: ideal for verifying changes right away.
| Tool | Description | Permission |
|---|---|---|
list_domains read | Listet die Domains des API-Key-Kunden (paginiert, optionale Substring-Suche). Parameters: search, page, page_size (*Â required) | domain:read |
get_domain read | Liest die Details einer Domain (Status, Laufzeit, Registrierungsdaten). Parameters: domain* (*Â required) | domain:read |
check_domain_available read | PrĂĽft ĂĽber die regfish-Registry-Abfrage, ob eine Domain noch registrierbar ist (dieselbe Quelle wie die Domain-Suche auf regfish.de). Funktioniert fĂĽr JEDE Domain, nicht nur fĂĽr die des Kontos. Parameters: domain* (*Â required) | domain:read |
get_nameservers read | Liest die aktuellen Nameserver einer Domain sowie die verfĂĽgbaren Vanity-NS-Sets des Kontos. Parameters: domain* (*Â required) | domain:read |

Security
Guardrails
Role-based API keys (RBAC): tools are filtered by permission, and the permission is additionally enforced in the API behind the MCP server, not just in the MCP layer.
The Domain Guardian applies here too: domains with active protection rules block API changes and require confirmation in the dash.
Nameserver changes via MCP are restricted to your own vanity NS sets: no free-form nameservers.
Per-key rate limits and anomaly detection: unusual delete/change bursts temporarily lock writes (reads stay available).
No tool with payment impact: registration, transfer, and renewal deliberately do not run through MCP.
Every write tool call is audited (key, customer, target, outcome).
Outlook
The tool contract is versioned and grows additively: web hosting arrived with version 1.2 (read-only), email tools are next. Internal API migrations never change the contract. Tool names and schemas stay identical.
