Qualität und Sicherheit
Basierend auf einer automatisierten Analyse der Tool-Definitionen und der Einhaltung des Protokolls.
Kontextkosten
Dies ist die ungefähre Anzahl der Tokens, die jedes Mal verbraucht werden, wenn die Tools des Servers in den Kontext eines Modells geladen werden. Höhere Werte verringern die Aufmerksamkeit, die für andere Aufgaben verfügbar ist.

"type": "object",
"properties": {},
"additionalProperties": false
}⚪lookup_ip(ip)
Validate an IPv4/IPv6 address and return its version, scope (public/private/loopback/...), country, ASN and network owner (DB-IP Lite + IPtoASN data).
Eingabe-Schema
{
"type": "object",
"properties": {
"ip": {
"type": "string",
"description": "IPv4 or IPv6 address"
}
},
"required": [
"ip"
]
}🟢validate_ip(ip)

"ip": {
"type": "string"
}
},
"required": [
"ip"
]
}⚪batch_lookup_ip(ips)
Look up 1-100 IPv4/IPv6 addresses at once. Each result has version, scope, country, timezone, ASN, network owner and flags (is_tor, is_datacenter, provider).

}🟢estimate_ai_cost(text, tokens, output_tokens)
