SQLGuard — Execution Certificate Firewall — questions

Answers built from our own checks of this server.

What can SQLGuard — Execution Certificate Firewall do?

It exposes 24 tools, read directly from the server on our last check. Among them: sqlguard_affiliate, sqlguard_balance, sqlguard_bind, sqlguard_buy, sqlguard_catalog, sqlguard_cert and 18 more. 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 SQLGuard — Execution Certificate Firewall working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 184 of 184 checks got a reply (100.0%), average response time 269 ms. The bar chart above shows every period we have measured.

Is SQLGuard — Execution Certificate Firewall still maintained?

The linked repository no longer exists on GitHub — it was deleted or made private. We show this because it changes what you can expect: an unmaintained server may keep answering for months and then stop without warning.

How do I connect SQLGuard — Execution Certificate Firewall?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does SQLGuard — Execution Certificate Firewall need an API key?

No. SQLGuard — Execution Certificate Firewall completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 24 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is SQLGuard — Execution Certificate Firewall?

It answers our handshake in 269 ms on average, which is faster than 51% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
