Available tools 5

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

audio

create_audio_crossword

Create an audio crossword puzzle URL. Unlike the classic crossword, clues are not text hints: each word itself is played back as audio, so the player hears the word and must spell it. You must provide only the list of words (no hints). The list must have between 3 and 30 words. If user specifies count/topic, generate appropriate words first, then call this tool with the words parameter.

cross

create_cross_math

Create a cross-math puzzle URL. A cross-math puzzle is a crossword-shaped grid of arithmetic expressions (e.g. "12 + 7 = 19") where some numbers are hidden and the player must fill them in. All parameters are optional; sensible defaults are used when omitted.

crossword

create_crossword

Create a crossword puzzle URL. You must provide the list of words and hints. The list must have between 3 and 30 pairs words/hints. If user specifies count/topic, generate appropriate words and hints first, then call this tool with the words parameter.

cryptogram

create_cryptogram

Create a cryptogram puzzle URL. You must provide the secret sentence/message to encode (at least 5 distinct letters). The player decodes a substitution cipher to reveal this sentence. Optionally provide hint words: clues shown alongside the puzzle, in format "word: hint" (one per line), where every letter of each word must already appear in the sentence. If the user specifies a topic instead of a sentence, generate an appropriate sentence first, then call this tool with it.

word

create_word_search

Create a word search puzzle URL. You must provide the list of words (no hints needed). The list must have between 3 and 30 words. If user specifies count/topic, generate appropriate words first, then call this tool with the words parameter.

Oh, my Dots! — questions

Answers built from our own checks of this server.

What can Oh, my Dots! do?

It exposes 5 tools, read directly from the server on our last check. Among them: create_audio_crossword, create_cross_math, create_crossword, create_cryptogram, create_word_search. 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 Oh, my Dots! 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 706 ms. The bar chart above shows every period we have measured.

How do I connect Oh, my Dots!?

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 Oh, my Dots! need an API key?

No. Oh, my Dots! 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 Oh, my Dots!?

It answers our handshake in 706 ms on average, which is faster than 15% 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.
