DeducePuzzles in your assistant
Today's board is a verified single-solution puzzle at medium difficulty, in the pattern of IBPS, SBI, and RRB PO/Clerk reasoning. Circular seating, row seating, box arrangement, and order and ranking also follow SSC. The same board is shared by everyone in the app that day. You get three attempts and a hint that names a clue number.
Last updated: 17 October 2026. The server address is https://mcp.deducepuzzles.com/mcp.
What you can ask for
Seating arrangements (row, circular, square, double-row, and two-variable), floor puzzles, box arrangements, scheduling puzzles, and order and ranking. The server does not serve syllogism, blood relations, quant, English, or general awareness.
The three tools
- get_daily_puzzle. Returns today's people, clues, and question, plus an attempt id. It does not include the solution.
- submit_attempt. Grades one arrangement. A wrong guess says how many attempts are left. The solution is included only once the round is finished. Chat text is not graded; only the arrangement sent to this tool is.
- get_hint. Names one clue number to re-read. It does not name a person, a seat, a floor, or a rank.
Attempts are counted per conversation, not per person. There is no sign-in. A correct solve can show how that time compares with other ranked solves of the same board in this app, once five ranked solves exist. Only the first completed round for that anonymous token today is ranked. A second round, a round that already saw the solution, or a solve under five seconds is not ranked and states no percentile. That is not the public leaderboard on deducepuzzles.com. After a correct solve, the reply can include a link to practice the full timed set on the website.
Integrity of attempts and rankings
- Server-issued ids. The attempt id and the anonymous player token are created and signed by the server. An id the caller makes up, or alters, is rejected. Ids are not tied to an account or session, so a round is reached only through the id returned to the conversation that opened it, and that id cannot be guessed.
- Server timing. Solve time is measured between two server timestamps: when the board was issued and when the correct arrangement arrived. A time sent by the caller is never used.
- Replays are not ranked. Only the first completed round for a token today can be ranked. A repeat round, a round that already saw the solution, or a solve under five seconds never enters the comparison.
- Rate cap. The number of ranked solves admitted per minute is capped, so a burst of scripted solves cannot reshape the comparison.
Data
The server does not receive your assistant account, your name, or your email. What it does keep, for how long, is in the privacy policy. The terms for this channel are there too. Play here does not create a DeducePuzzles account and does not sell anything.

How puzzles are verified
Before a puzzle is stored or served, a solver checks every clue and keeps the puzzle only when exactly one arrangement satisfies all of them. A puzzle with no answer or with more than one answer is discarded and another is generated. The solution is not included in get_daily_puzzle. It is returned only after the round is finished. Everyone who plays that board that day gets the same clues. Boards follow the reasoning formats used in IBPS, SBI and SSC papers, and in RRB PO/Clerk. Deduce does not claim that a puzzle matches the difficulty of a recent paper, or that every puzzle introduces a new pattern.
