tools

Zero Core Verify — questions

Answers built from our own checks of this server.

What can Zero Core Verify do?
It exposes 5 tools, read directly from the server on our last check. Among them: get_service_quality, health, list_tools, report_outcome, verify_outcome. 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 Zero Core Verify 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 369 ms. The bar chart above shows every period we have measured.
Is Zero Core Verify 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 Zero Core Verify?
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 Zero Core Verify need an API key?
No. Zero Core Verify completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 5 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Zero Core Verify?
It answers our handshake in 369 ms on average, which is faster than 37% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
How many people use Zero Core Verify?
The npm package @meltingpixels/zero-core-verify was installed 14 times in the last week. Week over week that is -18%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
