Anlyon alternative

1 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.

Tools

Grouped by what each tool does, most consequential first. Open one for its reasons and full description; descriptions are the publisher's own words.

    Why it is in this group

    • The name "create_sandbox" says "create": a word for a change.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

    • Warn

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

      What this check looks for
    Description, as the server wrote it
    Creates a shareable link to a playground that runs the given code in the browser (PHP in WebAssembly), with no account and nothing to install. Give only the files you change or add: the others stay as in the starting project (see get_starter). Nothing is stored: the code travels inside the link, after the "#". The page asks the visitor before running code received by a link.

    Annotations the server declares

    • idempotentHint: true
    • openWorldHint: false

    Why it is in this group

    • The name "get_starter" says "get": a word for reading.
    Description, as the server wrote it
    Returns the starting project of a playground (Symfony 8, Laravel 13 or plain PHP 8.5 with Composer autoloading): its files, the paths you may create or edit, and, for Symfony and plain PHP, the Composer packages you may add. Call it before create_sandbox to write code that fits the project. Configuration files (config/, bootstrap/) are listed in config_files; ask for their content with include_config when you need to change one.

    Annotations the server declares

    • readOnlyHint: true
    • openWorldHint: false
  • read_sandboxReads a playground link (https://<site>/bac-a-sable/...Reads text others writeCan send data outNo findings

    Why it is in this group

    • The name "read_sandbox" says "read": a word for reading.

    What it can reach

    • untrusted-inputThe description's first sentence says "read" and "http": it reads web pages, which anyone can write.
    • untrusted-inputThe input takes a URL (input.url), and the tool reads it: it reads web pages, which anyone can write.
    • outboundThe input takes a URL (input.url): a request to a URL can carry data to whoever runs it.

    Claude Code: ask, because it is tagged outbound.

    Description, as the server wrote it
    Reads a playground link (https://<site>/bac-a-sable/... or /en/playground/...#code=..., or a short link /bac-a-sable/s/<id> or /en/playground/s/<id>): returns the framework and the files that differ from the starting project, to review or fix the code someone shared.

    Annotations the server declares

    • readOnlyHint: true
    • openWorldHint: false

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.

Reads private data0
Reads files, mail, messages, databases, secrets, calendars or repositories.
Reads text others write1
Brings in text someone else can write: web pages, inbound email, messages, issues and comments.
Can send data out1
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.

    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.

Run in a terminal.

Claude Code permissions

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

.claude/settings.json
{
  "permissions": {
    "allow": [
      "mcp__php-playground__get_starter"
    ],
    "ask": [
      "mcp__php-playground__create_sandbox",
      "mcp__php-playground__read_sandbox"
    ],
    "deny": []
  }
}

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 php-playground. Review it before you use it.

Pin

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