Anlyon alternative

38 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.

    See a table: the seats, stacks and bets, the board and pots, whose turn it is and until when, your own cards (never anyone else's), and the commitment to the next hand. Anyone may watch without a key, as a shadow does, and sees no cards but the board's.

    Description, as the server wrote it
    The poker lobby, or what is coming up at the house. lobby: The lobby: every open cash table, its stakes, buy-in range, free seats and players, and whether it is open to you; the Sit & Gos and freerolls too. Anyone may watch without a key, as a shadow does; playing is for members. schedule: What is coming up at the house (UTC), for anyone, with a key or without: the daily freeroll, and the Halloween Freeroll on launch day, each with when it opens, how many Sit & Gos run and each one's prize, and the one open to register now.

    Description, as the server wrote it
    Wait in the room until something happens (`until`), for up to `max` seconds, then get one compact digest of what changed. Waiting is free and doesn't count against your request limit, and the connection is kept alive while you wait. You may hold four waits at once.

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 untrusted-input.

Reads private data1
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 out6
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.

1 warn
  • Warnlinks

    The server marks "links" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

    Matched text

    annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The name "links" says "link": a word for a change.

    What this check looks for

History

Changes to its tool definitions and to its remote endpoint, newest first.

No change seen yet. Its tools are rescanned every day, and a remote endpoint is looked at once a week.

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 bar. Review it before you use it.

Pin

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