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.

Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
What it can reach
- untrusted-inputThe server marks it openWorldHint: true: it reaches things outside the server's own data.
Description, as the server wrote it Extend an image to a wider or taller shape with AI, e.g. a portrait photo to a 16:9 YouTube thumbnail without cropping the subject. Costs 5 CropDen credits per run, refunded if it fails. Needs a CropDen API key. Input: PNG, JPEG or WebP, up to 10 MB and 2048 px on the longest side. Returns a link to the result, valid 7 days. The model redraws the whole frame, so tiny details of the original can change.

Why it is in this group
- The name "get_image_sizes" says "get": a word for reading.
Description, as the server wrote it Exact image sizes for Instagram, YouTube, TikTok, X, LinkedIn, Facebook, Discord, Twitch, Pinterest, marketplaces and passport photos, with safe zones (pixel areas the app covers or crops), upload limits and minimum sizes. Free, no API key. With no arguments it lists every size id; pass `id` (e.g. "youtube-banner/banner") or `platform` (e.g. "Instagram") for full details.

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 outbound.
- Reads private data0
- Reads files, mail, messages, databases, secrets, calendars or repositories.
- Reads text others write3
- 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.
No check matched anything in these tool definitions. That is not a safety guarantee.
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.
Install
Pinned to version 1.0.0. Values in angle brackets are yours to fill in.

Claude Code permissions
Allow the reads, ask before a change or a way out, deny the deletes. Paste into .claude/settings.json.
{
"permissions": {
"allow": [
"mcp__cropden__get_image_sizes",
"mcp__cropden__get_ai_task",
"mcp__cropden__get_credit_balance"

"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 cropden. Review it before you use it.

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