Anlyon alternative

7 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.

    Description, as the server wrote it
    Reads one Etsy listing from Etsy's API: title, the 13 tags, photo count and sizes, video, when it expires and whether it auto-renews, favorites, and whether the description mentions AI. Applies Etsy's published title/tag rules and returns the first thing to fix. Use for 'is my listing set up right?' and 'when does my listing expire?'.

Returns the shop's first problem and how many listings have it, per-listing issues, and Etsy's shop sales count (the shop's lifetime total, not per listing).

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 write9
Brings in text someone else can write: web pages, inbound email, messages, issues and comments.
Can send data out2
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.

  • WarnThe whole server

    The endpoint served tools/list without credentials, and the list has 7 tools that change things (7 write). Whether a call also works without credentials was not tested: tools are never called.

    Matched text

    https://www.growtsy.com/api/mcp: tools/list returned 9 tools to an anonymous client, including etsy_shop_sales (write), etsy_top_shops (write), etsy_niche_check (write), etsy_rank_check (write), etsy_shop_name_check (write) and 2 more

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.

Claude Code permissions

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

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 growtsy. Review it before you use it.
