Nothing serious here today

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

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

solve

solve_anagram

Use this when the user wants to unscramble letters or find all words that can be made from a set of letters (word unscrambler, anagram solver, letter-tile word finder), optionally with blank tiles (? or *) and filters for length, starts with, ends with, or contains. Returns dictionary matches grouped by length with counts (every match is counted; up to 25 words are listed per length) and tile points (standard letter values, no board bonuses). Does not check board placement or define words. Do not use for crossword patterns with known letter positions (use solve_word_pattern).

solve_word_guess

Use this when the user plays a 5-letter word guessing game with green/yellow/gray feedback and wants the remaining possible answers or a strong next guess (word game solver, guess helper). Takes previous guesses with their color feedback (G/Y/-), applies the standard repeated-letter rules, counts the words still possible and lists up to 60 of them, and ranks next guesses by expected information. Supports 4-8 letter variants and hard mode. Does not know today's answer and does not play the game. Do not use for unscrambling letters or crossword patterns.

solve_word_pattern

Use this when the user needs words that fit a pattern of known and unknown letters, such as a crossword answer (C?T, _A_E, 7 letters ending in ING), with optional letters that must or must not appear. Counts every matching dictionary word and lists up to 120 of them, common words first. Does not solve clues by meaning or look up definitions. Do not use for unscrambling a set of letters (use solve_anagram).

LetterLab Word Solver — questions

Answers built from our own checks of this server.

What can LetterLab Word Solver do?

It exposes 3 tools, read directly from the server on our last check. Among them: solve_anagram, solve_word_guess, solve_word_pattern. 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 LetterLab Word Solver 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 195 ms. The bar chart above shows every period we have measured.

How do I connect LetterLab Word Solver?

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 LetterLab Word Solver need an API key?

No. LetterLab Word Solver 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 LetterLab Word Solver?

It answers our handshake in 195 ms on average, which is faster than 74% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
