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
- 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.
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 Does this passport need a visa for this destination? Returns the requirement, the number of visa-free days, and — when that exact pair has been individually re-verified — the date it was. One pair per call, English only. Prefer it when the user wants a plain yes/no; switch to check_visa_requirement as soon as they need documents, fees, processing times, transit rules, or an answer in another language. Keyless and free: it costs nothing against an API key quota. An anonymous caller is capped at 30 DISTINCT pairs per day per network — asking the same pair again is always free, only widening costs. Free API key: https://visa.orizn.app/visa-api?source=mcp — 100 requests/month, no card, and it unlocks documents, fees, processing times, transit rules and 15 languages.

Why it is in this group
- The name "get_coverage_stats" says "get": a word for reading.
What it can reach
- private-dataThe description's first sentence says "database": it reads databases.
- untrusted-inputThe server marks it openWorldHint: true: it reaches things outside the server's own data.
Description, as the server wrote it How big the Orizn visa database is: pairs, passports, destinations, enriched records, translations and languages. Says nothing about any specific country pair — use quick_visa_check or check_visa_requirement for that. Keyless, free, and costs nothing against any quota. Call it when the user asks how complete the data is, or to confirm this server is reachable before a longer session.

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 outbound.
- Reads private data1
- 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
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__orizn-visa__get_coverage_stats"
],
"ask": [
"mcp__orizn-visa__quick_visa_check"
],
"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 orizn-visa. Review it before you use it.

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