Zero Core Tools missed one check this week

Everything else answered, so this is steady rather than shaky. We check every 15 minutes, which is how a one-off gets told apart from the start of a pattern, and how you hear about the next one within the hour instead of from your users.

Zero Core Tools — questions

Answers built from our own checks of this server.

What can Zero Core Tools do?

It exposes 9 tools, read directly from the server on our last check. Among them: analyze_sentiment, extract_structured_data, generate_content, health, list_tools, review_code and 3 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 Zero Core Tools working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 395 ms. The bar chart above shows every period we have measured.

How do I connect Zero Core Tools?

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 Tools need an API key?

No. Zero Core Tools completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 9 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Zero Core Tools?

It answers our handshake in 395 ms on average, which is faster than 38% 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 Tools?

The npm package @meltingpixels/zero-core-tools was installed 23 times in the last week. Week over week that is +127%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is Zero Core Tools open source?

We cannot say either way: written in TypeScript, 2 stars on GitHub and 2 open issues, but we could not determine the licence, and without one the code is not open source by default.
