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.

Tools

Grouped by what each tool does, most consequential first. Open one for its reasons and full description; descriptions are the publisher's own words.

    Why it is in this group

    • The name "get_availability" says "get": a word for reading.
    • The description's first verb is "open": a word for a change.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

    Findings

    • Warn

      The server marks "get_availability" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

    Description, as the server wrote it
    Open departure times and booking status for one tour on one date, from the American Ghost Walks booking system. Times are local to the tour. Check this before telling a guest a time is open; if it says availability is unknown or lists no times, send the guest to the booking link instead of guessing.

    Full details for one tour: description, stops, meeting spot with map link, duration, difficulty, FAQ, important info, cancellation/weather/age/pet policies and rating. Use for questions like 'how much walking is it?', 'can kids come?' or 'where do we meet?'. Answer only from what this returns; if it doesn't cover a question, give the phone number.

    Description, as the server wrote it
    Find American Ghost Walks ghost and history walking tours by city, optionally with a date range and party size.

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 untrusted-input or outbound.

Reads private data2
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.

    What this check looks for

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.

All changes to this server

Install

Pinned to version 1.0.0. Values in angle brackets are yours to fill in.

claude mcp add --transport http american-ghost-walks https://mcp.agwcrew.com/mcp
claude mcp add --transport http american-ghost-walks https://mcp.agwcrew.com/mcp

Run 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.

.claude/settings.json
{
  "permissions": {
    "allow": [
      "mcp__american-ghost-walks__search_tours",
      "mcp__american-ghost-walks__get_booking_link",
      "mcp__american-ghost-walks__get_tour_details"
    ],
    "ask": [
      "mcp__american-ghost-walks__get_availability"
    ],
    "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 american-ghost-walks. Review it before you use it.
