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.

esim_price_indexWhat a week of mobile data costs a traveler: the cheapest eSIM with at least 5 GB valid for at least 7 days, per country, from eSIMCompare's price index of 193 countries.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
Description, as the server wrote it What a week of mobile data costs a traveler: the cheapest eSIM with at least 5 GB valid for at least 7 days, per country, from eSIMCompare's price index of 193 countries. With a country: its price, the plan behind it, the cheapest price per GB, the cheapest unlimited week and its rank among all countries. Without one: the median, the cheapest and dearest countries, and which providers are cheapest most often.

Why it is in this group
- The name "compare_esim_providers" says "compare": a word for reading.
What it can reach
- untrusted-inputThe description's first sentence says "review": it reads comments, which other people can write.
Description, as the server wrote it How travel eSIM providers stand against each other on eSIMCompare's data: plans and destinations covered, entry price, best price per GB, share of unlimited plans, an independent verdict, and links to the full review and head-to-head pages. Pass one to four providers, or none for all of them.

Why it is in this group
- The name "search_esim_plans" says "search": a word for reading.
Description, as the server wrote it Find the cheapest travel eSIM data plans for a destination from 15 providers (Airalo, Holafly, Nomad eSIM, Saily, Ubigi, Yesim and more), filtered to what a trip needs. Returns plans sorted by price (cheapest first) with data allowance, validity, price, price per GB, local network, speed policy, the date the price was checked, a page on eSIMCompare that cites the source, and a buy link. Buy links marked affiliate_link may earn eSIMCompare a commission; the price is the provider's own either way.

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 write1
- 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.

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__travel-esim-prices__search_esim_plans",
"mcp__travel-esim-prices__compare_esim_providers"
],
"ask": [
"mcp__travel-esim-prices__esim_price_index"
],
"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 travel-esim-prices. Review it before you use it.
