SSL Certificate Check Skill

What this skill does

Give your agent certificate visibility. Call it as an MCP tool to read a domain's SSL issuer, validity dates and key strength in real time. You switch it on with a single toggle — no SDK and no endpoint wiring — and it answers over MCP or REST using the same key as every other skill.

Ways to use it

Domain intelligence in one skill

Enable SSL Certificate Check so your app can add ssl certificate check to your app — pull records, health, or ownership — without integrating a WHOIS/DNS provider per data type.

A tool for security & research agents

Over MCP, your model calls sslchecker to ground a claim about a domain in real records before it reasons about risk.

Enrich from your backend

Call SSL Certificate Check over REST to add ssl certificate check to your app across a list of domains in a scheduled job, one key for all of it.

Use it in your app

Once enabled, this skill is reachable two ways — pick whichever fits how you build. Both use the same key.

For AI agentsMCP

It appears to your model as a callable tool. No extra code — the agent invokes it when a task needs it.

sslchecker

For apps & backendsREST

Call it from your server with one request and your key. Node, Python, Go — anything that can send a GET.

GET /v1/sslchecker

Ask your agent

“Enable SSL Certificate Check and ask your agent to add ssl certificate check to your app.”
“Pull the records and health for example.com.”

How to connect it over MCP or REST.

How do I add SSL Certificate Check to my app or agent?

Enable the SSL Certificate Check Skill on VerveKit, then reach it two ways with the same key: over MCP (it appears to your agent as the sslchecker tool) or over REST (call it from any backend). No SDK to install and no endpoint to wire.

MCP or REST — which should I use?

Both work off one key. Use MCP when an AI agent should decide when to add ssl certificate check to your app — the skill shows up as a callable tool. Use REST when your own server-side code should call it directly. Many apps use both.

Which agents and frameworks does it work with?

Any MCP client — Claude, Cursor, LangChain, and custom agents all speak the Model Context Protocol, so SSL Certificate Check appears as a standard tool with nothing skill-specific to integrate.

How many credits does a SSL Certificate Check call cost?

Each call costs 5 credits. Every skill rides the same key and the same connection, so enabling more skills doesn't add more integrations to manage.

Do I need to install anything?

No SDK and no endpoint wiring — enabling the skill is a toggle. You point your agent at the VerveKit MCP endpoint (or call REST) and SSL Certificate Check is available immediately.

Where does the data come from, and what shows on my bill?

VerveKit runs on APIVerve, our production data engine; SSL Certificate Check is one of 300+ skills on the same key. Invoices and card statements show APIVERVE.
