Anlyon alternative

3 of these tools change something. Run those as governed actions.

Declare what an action changes, and Anlyon puts it under a shared limit, binds every approval to the exact request, and grades the outcome. It works on any HTTPS API you can describe as an action.

Anlyon does not run, proxy or govern this MCP server. A tool your own code calls directly is not routed through Anlyon and is not governed by it.

      What this check looks for
    Description, as the server wrote it
    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.

    Description, as the server wrote it
    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.

    Why it is in this group

    • The name "submit_attempt" says "submit": a word for a change.
    Description, as the server wrote it
    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.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.

Exfil surface

Which tools read private data, which read text someone else can write, and which can send data out. One of each is a path a prompt injection can use.

No private-data, untrusted-input, outbound path in this server alone: no tool is tagged private-data or untrusted-input or outbound.

Reads private data0
Reads files, mail, messages, databases, secrets, calendars or repositories.
Reads text others write0
Brings in text someone else can write: web pages, inbound email, messages, issues and comments.
Can send data out0
Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL.

Other servers in the same agent add their own tools to these paths. Audit your whole setup to see them together.

Findings

Matches of fixed checks, with the text they matched.

Claude Code permissions

Allow the reads, ask before a change or a way out, deny the deletes. Paste into .claude/settings.json.

  "permissions": {
    "allow": [],

Tools that only read are allowed, tools that change things ask first, tools that delete or cancel are denied. A read that can send data out (it takes a URL, say) asks first too. It assumes the server is installed as daily-puzzle. Review it before you use it.

Pin

Keep the decision: fail CI when the tools change, follow every change, or show a badge.

Pin in CI
