Should I use this
Quality & Safety
Based on automated analysis of tool definitions and protocol compliance.
Context Cost
This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

Tool inventory
Tools (4)
🟢scan_domain(domain)
Scores how well a dApp or website domain is protected against hijacking: registrar transfer/update locks, registry lock, DNSSEC, CAA, expiry, nameserver consistency across resolvers, SRI on third-party scripts and the Content-Security-Policy header. Returns a 0-100 score, each check with pass/fail/unknown and advice. Results are cached for an hour.
Input Schema
{
"type": "object",
"properties": {
"domain": {
"type": "string",
"description": "Domain name, e.g. app.example.com. A URL is accepted too; only the host is used."
}
},
"required": [
"domain"
],
"additionalProperties": false
}🟢check_registry_lock(domain)
Reads the domain's EPP status codes from RDAP and tells whether registry lock (serverUpdateProhibited + serverTransferProhibited) is on, partly on or off, and which registrar-level locks are set.

},
"required": [

],
"additionalProperties": false
}🟢check_sri(url)
Loads a public page and lists every script, stylesheet and preload it pulls in. For third-party files, checks whether an integrity= hash is present and matches, and returns a ready sha384 hash for files that have none.

"type": "object",
"properties": {
"url": {
"type": "string",

}
},
"required": [
"url"
],
"additionalProperties": false
}🟢check_seal_dns_registrar(domain)
Goes through the 16 controls of the SEAL Security Frameworks certification for DNS & Registrar and marks what public data shows for each: ok, partial, gap, not visible from outside, or a process control the team has to document itself. Includes DNSSEC, CAA, SPF/DMARC/MTA-STS, locks, expiry and security.txt.
