Anlyon alternative
Run the operations that matter 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 "resolve_destination" says "resolve": a word for reading.
Description, as the server wrote it Find the Guestit destination for a place name before searching stays. Pass the place alone, such as Åre or Stockholm. Returns only places with Guestit stays, at most one. When nothing matches, ask the user about a larger place nearby.

search_staysSearch public Guestit accommodation using a location_id from resolve_destination.No findings
Why it is in this group
- The name "search_stays" says "search": a word for reading.
Description, as the server wrote it Search public Guestit accommodation using a location_id from resolve_destination. Refine by resending the full filter set. Each stay is a short card; read house rules and the cancellation policy with stay_details or compare_stays before recommending one. Prices are estimates for the supplied dates and guests, with no inventory hold. Stays that fail the live check for those dates are left out, so a page can hold fewer than its limit. Nightly-rate filters use indexed average rates in SEK, not final stay totals. Pagination counts reflect the search index; current public rows may be fewer. Complete booking on the returned Guestit website link, which opens with the dates and guests filled in.

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 untrusted-input or outbound.
- Reads private data0
- Reads files, mail, messages, databases, secrets, calendars or repositories.
- Reads text others write0
- 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 mcp add --transport http core https://core.guestit.se/mcpclaude mcp add --transport http core https://core.guestit.se/mcpRun in a terminal.
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__core__resolve_destination",
"mcp__core__search_stays",
"mcp__core__stay_details",
"mcp__core__compare_stays"
],
"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 core. Review it before you use it.
Pin
Keep the decision: fail CI when the tools change, follow every change, or show a badge.
Pin in CI
Fail a build when the tools you reviewed are not the tools the server serves today.
