Penniless Data Utilities 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.

Penniless Data Utilities — questions

Answers built from our own checks of this server.

What can Penniless Data Utilities do?

It exposes 9 tools, read directly from the server on our last check. Among them: cron_next_run, dns_lookup, domain_whois, email_validate, github_repo_stats, repair_json 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 Penniless Data Utilities 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 700 ms. The bar chart above shows every period we have measured.

How do I connect Penniless Data Utilities?

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 Penniless Data Utilities need an API key?

No. Penniless Data Utilities 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 Penniless Data Utilities?

It answers our handshake in 700 ms on average, which is faster than 13% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is Penniless Data Utilities open source?

We cannot say either way: written in JavaScript and 0 stars on GitHub, but we could not determine the licence, and without one the code is not open source by default.
