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

generate

generate_crossword

Use this when the user wants a crossword puzzle (crossword maker, crossword puzzle maker, crossword for a class or a vocabulary list) built from answers and clues. Builds a valid interlocking grid with standard numbering and Across/Down clue lists, reports any answers that could not be placed, shows a playable crossword, and returns a printable PDF with an answer key. Needs 4-40 answer-and-clue pairs; if the user gives only words, write a short clue for each first. Answers are reduced to letters A-Z. Does not solve existing crosswords or answer single clues, and does not make symmetric newspaper-style grids.

generate_sudoku

Use this when the user wants a new sudoku puzzle to play or print (sudoku generator, printable sudoku with answers, easy sudoku for kids, hard sudoku). Generates a classic 9x9 sudoku at easy, medium or hard difficulty, checked by a solver for a single solution, playable in the chat with pencil notes, plus a printable PDF with the answer key. Does not solve a sudoku the user already has, explain solving strategies, or make 4x4, 6x6 or variant sudoku.

generate_word_search

Use this when the user wants a word search puzzle (word find, word search maker, printable word search for kids or a class) from a list of words. Accepts 5-40 words for a letter grid: right and down for easy, adding diagonals for medium, all 8 directions including backwards for hard; checks placed words for duplicate occurrences and reports words left out. Shows a playable puzzle and returns a printable PDF with an answer key. Not for crosswords (use generate_crossword) and does not find words in a grid the user already has.

GridSmith Puzzle Maker — questions

Answers built from our own checks of this server.

What can GridSmith Puzzle Maker do?

It exposes 3 tools, read directly from the server on our last check. Among them: generate_crossword, generate_sudoku, generate_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 GridSmith Puzzle Maker 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 340 ms. The bar chart above shows every period we have measured.

How do I connect GridSmith Puzzle Maker?

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 GridSmith Puzzle Maker need an API key?

No. GridSmith Puzzle Maker completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 3 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is GridSmith Puzzle Maker?

It answers our handshake in 340 ms on average, which is faster than 42% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
