devutils does not always answer

Over the last week it answered 99.3% of our checks. We check every 15 minutes, so you hear about the next outage within the hour — not from your users.

devutils — questions

Answers built from our own checks of this server.

What can devutils do?

It exposes 10 tools, read directly from the server on our last check. Among them: base64_decode, base64_encode, csv_to_json, hash_text, json_format, json_minify and 4 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 →

What is devutils mostly used for?

Its tools cluster around json and base64. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.

Is devutils 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 150 ms. The bar chart above shows every period we have measured.

Is devutils 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 devutils?

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 devutils need an API key?

No. devutils completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 10 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is devutils?

It answers our handshake in 150 ms on average, which is faster than 83% 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.
