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.

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.

6 tools

Only reads 6Show 6 read-only tools
  • deltasReturn deltas_vs_prev (and recheck notes, if any) for a baseline cut.Reads private dataNo findings

    Why it is in this group

    • The description's first verb is "return": a word for reading.

    What it can reach

    • private-dataThe description's first sentence says "return" and "note": it reads notes.
    Description, as the server wrote it
    Return deltas_vs_prev (and recheck notes, if any) for a baseline cut. These are the change notes recorded on that JSON file. This tool does not compute new diffs.

    Annotations the server declares

    • title: Baseline deltas
    • readOnlyHint: true
    • destructiveHint: false
    • idempotentHint: true
    • openWorldHint: false
  • demand_mixReturn hot demand categories recorded on a public baseline.No findings

    Why it is in this group

    • The description's first verb is "return": a word for reading.
    Description, as the server wrote it
    Return hot demand categories recorded on a public baseline. mention_count values are heuristics copied from the JSON cut, not hit counts. This tool never invents additional categories or counts.

    Annotations the server declares

    • title: Demand mix
    • readOnlyHint: true
    • destructiveHint: false
    • idempotentHint: true
    • openWorldHint: false
  • get_programmeLook up one verified programme by exact or fuzzy name.No findings

    Why it is in this group

    • The name "get_programme" says "get": a word for reading.
    Description, as the server wrote it
    Look up one verified programme by exact or fuzzy name. A miss returns match_kind=none — this tool does not invent a programme.

    Annotations the server declares

    • title: Get a programme
    • readOnlyHint: true
    • destructiveHint: false
    • idempotentHint: true
    • openWorldHint: false
  • latest_briefReturn the public Frontier Signal brief markdown for a date.No findings

    Why it is in this group

    • The description's first verb is "return": a word for reading.
    Description, as the server wrote it
    Return the public Frontier Signal brief markdown for a date. Gated watchlist sections are stripped if present. A brief is never synthesised.

    Annotations the server declares

    • title: Latest public brief
    • readOnlyHint: true
    • destructiveHint: false
    • idempotentHint: true
    • openWorldHint: false
  • list_buyer_programmesList verified buyer programmes (and other sources) from a public baseline.No findings

    Why it is in this group

    • The name "list_buyer_programmes" says "list": a word for reading.
    Description, as the server wrote it
    List verified buyer programmes (and other sources) from a public baseline. Returns name, url, band, referral, categories, status, notes, and type. An empty list means no rows matched — programmes are never invented.

    Annotations the server declares

    • title: List buyer programmes
    • readOnlyHint: true
    • destructiveHint: false
    • idempotentHint: true
    • openWorldHint: false

    Why it is in this group

    • The name "list_observed_dates" says "list": a word for reading.
    Description, as the server wrote it
    List baseline dates (and public brief dates) available in this checkout. No live fetch is performed.

    Annotations the server declares

    • title: List observed dates
    • readOnlyHint: true

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 data1
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.

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__frontier-signal__list_buyer_programmes",

  }
}

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 frontier-signal. Review it before you use it.
