## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-05.

- **Endpoint Security**: 63/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS enforcement could not be verified: the plaintext port answered with HTTP 405, which proves neither a plaintext path nor enforcement.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 34/100
  - 0% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 1002 tokens (~250/item across 4 items; 3 tools + 1 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 20/100
  - Stability observed for 6 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 5 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.
  - Supports UI / widget rendering.

## MCP tools (3)

### `get_daily_puzzle` (~375 tokens)

Today's bank exam puzzle

Use this when the user wants to play today's DeducePuzzles board or a daily bank-exam arrangement puzzle. Returns a verified single-solution puzzle at medium difficulty from a daily rotation of seating, floor, box, scheduling, and ranking. Patterns follow IBPS, SBI, and RRB PO/Clerk; circular, row, box, and ranking also follow SSC. For a specific supported type, pass kind: if it is not today's type, the tool reports that limitation without starting a round. Do not use for syllogism, blood relations, quant, English, general awareness, general exam advice, product comparisons, billing or account support, or solving a puzzle supplied by the user. Not for planning real seating, seating charts, or schedules for an event, classroom, office, or exam hall. Attempts are counted per conversation, not per person. Omit attemptId to start; pass the returned attemptId and playerToken on later calls. Starting stores an anonymous round; it does not sign the user into the website.

Input parameters:

- `attemptId` (string): Conversation id returned by get_daily_puzzle. Attempts are counted per conversation, not per person. Pass this same id on every later call in the conversation.
- `kind` (string): Optional requested arrangement type. This checks today's rotation; it does not generate another type. Omit for any daily board. Use row for linear seating, circular for circular seating, and ranking…
- `playerToken` (string): Anonymous token returned by an earlier get_daily_puzzle. Pass it back to keep this app's streak. Omit it to start a new one. Not an account, and not a website streak. 16–64 letters, digits, _ or -.

### `submit_attempt` (~335 tokens)

Grade an arrangement

Use this when the user submits an order for today's DeducePuzzles board (seating, floor, box, scheduling, or order and ranking). Grades that one arrangement: right or wrong, attempts left, and whether the round is finished. A wrong guess does not say which clues it broke. The solution is included only once the round is finished. A percentile is included only when the arrangement is right, this is the player's first completed round today, the solve took at least five seconds, and at least five ranked solves of today's board exist here. A replay, a round that already saw the solution, or a solve under five seconds states no percentile. A placement exists only in this result. Do not use to grade a puzzle this server did not serve. Attempts are counted per conversation, not per person.

Input parameters:

- `arrangement` (array, required): Every person from today's board exactly once, in the order the question asks. Index 0 is position 1 (lowest floor, left end of a row, rank 1, or day 1). Example: ["Aman", "Beena", "Chetan", "Diya"].
- `attemptId` (string, required): Conversation id returned by get_daily_puzzle. Attempts are counted per conversation, not per person. Pass this same id on every later call in the conversation.
- `playerToken` (string): Anonymous token returned by an earlier get_daily_puzzle. Pass it back to keep this app's streak. Omit it to start a new one. Not an account, and not a website streak. 16–64 letters, digits, _ or -.

### `get_hint` (~169 tokens)

Clue-number hint

Use this when the user asks for a hint on today's DeducePuzzles board. Names one clue to re-read, by number only. Does not reveal a person, a seat, a floor, or a rank. Do not use for a solution or a walkthrough. Attempts are counted per conversation, not per person.

Input parameters:

- `attemptId` (string, required): Conversation id returned by get_daily_puzzle. Attempts are counted per conversation, not per person. Pass this same id on every later call in the conversation.
- `playerToken` (string): Anonymous token returned by an earlier get_daily_puzzle. Pass it back to keep this app's streak. Omit it to start a new one. Not an account, and not a website streak. 16–64 letters, digits, _ or -.
