DNSSEC Check Skill
The tool
Give your agent DNSSEC visibility. Call it as an MCP tool to verify a domain's DNSSEC chain of trust in real time — no resolver to run.
Once your client is connected to the VerveKit MCP server, this appears in its tool list as DNSSECCheckSkill. It is read-only and open-world: it fetches, it never mutates anything on your side, so most clients will call it without asking you to confirm.
{
"name": "DNSSECCheckSkill",
"arguments": {
"domain": "cloudflare.com"
}
}What that looks like in a conversation
You don't name the tool — the model picks it. Asking about cloudflare.com in the terms this source covers is enough for it to reach for DNSSECCheckSkill on its own.
Connecting
One server URL covers every skill in the catalog, including this one. Authorization is OAuth — the client opens a browser once and there is no key to paste into a config file.

"vervekit": {

Arguments
These are the properties on the tool's inputSchema, so a well-behaved client validates them before the call is made.
| Argument | Type | Example | Description |
|---|---|---|---|
domainRequired | string | cloudflare.com | The domain name to check DNSSEC configuration for |
What the model gets back
The result carries a structuredContent object matching the tool's declared outputSchema, so a client can read fields without parsing prose. status is "ok" on success and error is null; a null field means the value wasn't available for that input, not that the call failed.
{
"status": "ok",
"error": null,
"data": {
"domain": "cloudflare.com",
"dnssecEnabled": true,
"valid": true,
"records": {
"dnskey": 3,
"ds": 2,
"nsec": "NSEC3"
},
"errors": [],
"details": {
"dnskeyCount": 3,
"dsCount": 2
},
"status": "DNSSEC is properly configured with DS records at parent",
"recommendation": "DNSSEC is properly configured",
"riskScore": 5,
"riskLevel": "low"
}
}Fields
| Field | Type | Example | Description |
|---|---|---|---|
domain | string | cloudflare.com | Domain that was checked |
dnssecEnabled | boolean | true | Whether DNSSEC is enabled |
valid | boolean | true | Whether DNSSEC configuration is valid |
recordsPremium | object | {…} | DNSKEY and DS record details |
records.dnskeyPremium | number | 3 | Number of DNSKEY records published by the zone |
records.dsPremium | number | 2 | Number of DS records held by the parent zone |
records.nsecPremium | string | NSEC3 | Number of NSEC or NSEC3 records used to prove non-existence; null when none were returned |
errors | array | [] | Problems found in the chain of trust; empty when DNSSEC validates |
details | object | {…} | Record counts behind the verdict |
details.dnskeyCount | number | 3 | Number of DNSKEY records seen |
details.dsCount | number | 2 | Number of DS records seen at the parent |
status | string | DNSSEC is properly configured with DS records at parent | Plain-language verdict on the domain's DNSSEC configuration |
recommendation | string | DNSSEC is properly configured | What to do about the current configuration |
riskScorePremium | number | 5 | Composite 0-100 DNSSEC deployment-health score. A fully valid chain of trust scores low; a domain that published keys but never lodged its DS record at the parent zone (a broken chain that can break resolution) scores high; an undeployed domain scores in between |
riskLevelPremium | string | low | Risk band derived from the score: low, medium or high |
Failure modes
Errors come back as tool errors with a sentence the model can act on, not a bare status code.
| Status | What it means |
|---|---|
400 / 422 | The arguments didn't validate. The message names the offending one. |
401 | The OAuth session is invalid or expired — reconnect the server. |
403 | Out of credits. Not a bad key — the month's allowance is spent. |
404 | This skill isn't part of VerveKit. Check the catalog. |
429 | Brief rate limit. Retrying after a moment succeeds. |

Frequently asked questions
Do I have to tell the agent to use DNSSECCheckSkill?
No. The tool's name and description are in the model's context once the server is connected, so it selects the tool when the question calls for it. Naming it explicitly works too and is useful when you want to force the call.
Does connecting the server expose every tool at once?
Yes — one connection lists the whole VerveKit catalog. Clients with a tool budget can usually filter the list; the credit cost is per call, so an unused tool costs nothing.
What does a call cost?
5 credits each time the tool actually runs. A model that reasons about the tool without calling it costs nothing.
Is there a REST version of this?
Yes — the same source is available as a plain HTTPS endpoint on APIVerve, linked above. Same data, same credits, same account.
