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.

Why it is in this group
- The name "check_store" says "store": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
What it can reach
- untrusted-inputThe server marks it openWorldHint: true: it reaches things outside the server's own data.
Findings
- Warn
The server marks "check_store" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

Description, as the server wrote it Store platform (Shopify, WooCommerce, BigCommerce, other store or not a store), catalog size, price range and store age for a domain, plus the tracking pixels and marketing tools on its homepage (Meta, Google Ads, TikTok, Pinterest, Klaviyo, Triple Whale and more). Results under a day old are reused; fresh checks are limited per day (10 without signing in, 50 signed in).

Why it is in this group

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 Is this store running Meta ads? Finds the Facebook page behind a store domain and returns advertising since, live ads, trend (new, scaling, stable, stopped), channels and store platform. Signed in: catalog size, price range, recent launches and store age (free plan: 5 new domains a day); Pro and up also get recent ads. Unknown domains are checked live in the Meta Ad Library, within a daily limit.

Why it is in this group
- The name "search_signals" says "search": a word for reading.
Description, as the server wrote it US ecommerce brands flagged on the latest day for a change in their Meta (Facebook/Instagram) ads: newly advertising, scaling, struggling or stopped, with store platform, live ad count and other ad channels. Defaults to new and scaling brands in every niche the caller's plan covers. Without signing in or on the free plan, brand names and domains are masked and only the niche filter applies. On paid plans each brand returned counts toward the account's monthly export rows (the same brand again that month is free).
Annotations the server declares
- title: Search ad signals
- 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 or outbound.
- Reads private data0
- Reads files, mail, messages, databases, secrets, calendars or repositories.
- Reads text others write2
- 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

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

"ask": [

],
"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 advertiserleads. Review it before you use it.
