Available tools 1

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

security
security_check_ssl
Use this when you need to check if a domain's SSL/TLS certificate is valid, when it expires, and who issued it. Returns structured certificate data in JSON. Returns: 1. valid (boolean) 2. expiryDate and daysRemaining 3. issuer (name, organization, country) 4. subject (CN, alt names) 5. protocol (TLS version) 6. securityGrade (A+ to F) 7. certificate chain details. Example output: {"domain":"example.com","valid":true,"expiryDate":"2026-12-15","daysRemaining":245,"issuer":{"name":"DigiCert","organization":"DigiCert Inc"},"protocol":"TLSv1.3","securityGrade":"A+"} Use this BEFORE deploying a website, FOR monitoring certificate expiration, auditing security posture, and validating HTTPS setup. Do NOT use for DNS lookup -- use network_lookup_dns instead. Do NOT use for HTTP headers analysis -- use network_analyze_headers instead. Do NOT use for port scanning -- use network_scan_ports instead.

SSL Checker API — questions

Answers built from our own checks of this server.

What can SSL Checker API do?
It exposes 1 tools, read directly from the server on our last check. Among them: security_check_ssl. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is SSL Checker API working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 32 ms. The bar chart above shows every period we have measured.
How do I connect SSL Checker API?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does SSL Checker API need an API key?
No. SSL Checker API completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 1 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is SSL Checker API?
It answers our handshake in 32 ms on average, which is faster than 99% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is SSL Checker API open source?
Yes — it is published under the MIT licence, written in TypeScript and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
