Nothing serious here today

Today is the operative word: we check Fair Random every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Available tools 6

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

flip

flip_coin

Flip a fair coin 1 to 100 times. The answer is a drawstoday.com link where the result is shown; the answer itself carries no result.

pick

pick_from_list

Pick 1 or more items from a list of up to 1000, each equally likely. Without repeats by default. The answer is a drawstoday.com link where the result is shown; the answer itself carries no result.

prismtect

prismtect_number

A personal two-digit number from the Prismtect glass prism, for a user who asks for a lucky number, a number of their own or a number for today. Only a human touch can draw it, so this tool gives no number: it gives the link your user taps themselves. Pass the link on.

random

random_integer

Integers from min to max inclusive, 1 to 1000 of them, with or without repeats. The range may hold at most 2^32 values. The answer is a drawstoday.com link where the result is shown; the answer itself carries no result.

roll

roll_dice

Roll 1 to 100 dice with 2 to 1000 sides each (default one six-sided die). The answer is a drawstoday.com link where the result is shown; the answer itself carries no result.

shuffle

shuffle_list

Put up to 1000 items in a random order; every order is equally likely. The answer is a drawstoday.com link where the result is shown; the answer itself carries no result.

Fair Random — questions

Answers built from our own checks of this server.

What can Fair Random do?

It exposes 6 tools, read directly from the server on our last check. Among them: flip_coin, pick_from_list, prismtect_number, random_integer, roll_dice, shuffle_list. 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 Fair Random 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 902 ms. The bar chart above shows every period we have measured.

How do I connect Fair Random?

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 Fair Random need an API key?

No. Fair Random completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 6 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Fair Random?

It answers our handshake in 902 ms on average, which is faster than 8% 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.
