Anlyon alternative

3 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.

Can't be undone 1Claude Code: ask
  • decode_codice_fiscaleRead back a codice fiscale: sex, birth date (one or two possible centuries), birth comune or foreign state valid on that date, the consonant codes of surname and name, and omocodia…1 finding

    Why it is in this group

    • The description's first verb is "read": a word for reading.
    • The description says "cannot be recovered".
    • The input takes a statement or command to run (input.code), which can change anything it can reach.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

    Findings

    • Warn

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

      Matched text

      annotations: {"readOnlyHint":true,"idempotentHint":true,"openWorldHint":false}; The description's first verb is "read": a word for reading.

      What this check looks for
    Description, as the server wrote it
    Read back a codice fiscale: sex, birth date (one or two possible centuries), birth comune or foreign state valid on that date, the consonant codes of surname and name, and omocodia. The full name cannot be recovered from a code. Fails with the reason when the format or the check character is wrong.

    Annotations the server declares

    • readOnlyHint: true
    • idempotentHint: true
    • openWorldHint: false
Changes things 2Claude Code: ask
  • compute_codice_fiscaleCompute the Italian codice fiscale (tax code) of a person from surname, name, sex, birth date and birth place, with the D.M.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
    Compute the Italian codice fiscale (tax code) of a person from surname, name, sex, birth date and birth place, with the D.M. 23/12/1976 rules. The place can be a comune ('Roma', 'Castro (LE)'), a foreign state ('Francia') or a codice catastale ('H501'); the code valid on the birth date is used. Returns the 16 characters and why each group has its value. The Agenzia delle Entrate may assign an omocodic variant: only it confirms a code.

    Annotations the server declares

    • readOnlyHint: true
    • idempotentHint: true
    • openWorldHint: false
  • verify_codice_fiscaleCheck that a codice fiscale is well formed, layer by layer: format, check character, a real birth date, a place code valid on that date, and optionally the surname and name letters…1 finding

    Why it is in this group

    • The input takes a statement or command to run (input.code), which can change anything it can reach.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

    Findings

    • Warn

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

      Matched text

      annotations: {"readOnlyHint":true,"idempotentHint":true,"openWorldHint":false}; The input takes a statement or command to run (input.code), which can change anything it can reach.

      What this check looks for
    Description, as the server wrote it
    Check that a codice fiscale is well formed, layer by layer: format, check character, a real birth date, a place code valid on that date, and optionally the surname and name letters. It says whether the code is written correctly, not whether the Agenzia delle Entrate has assigned it (only its own service does).

    Annotations the server declares

    • readOnlyHint: true
    • idempotentHint: true
    • openWorldHint: false
Only reads 1Show 1 read-only tool
  • lookup_placeSearch the 15,000 comuni of every era and the foreign states of the ANPR archive by name or by code (codice catastale like H501, Z-code like Z110).No findings

    Why it is in this group

    • The name "lookup_place" says "lookup": a word for reading.
    Description, as the server wrote it
    Search the 15,000 comuni of every era and the foreign states of the ANPR archive by name or by code (codice catastale like H501, Z-code like Z110). Returns up to 20 places with their province and the dates their code was valid. Give a date to keep only the places valid on it.

    Annotations the server declares

    • readOnlyHint: true
    • idempotentHint: true
    • openWorldHint: false

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.

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.

.claude/settings.json
{
  "permissions": {
    "allow": [
      "mcp__codice-fiscale__lookup_place"
    ],
    "ask": [
      "mcp__codice-fiscale__compute_codice_fiscale",
      "mcp__codice-fiscale__decode_codice_fiscale",
      "mcp__codice-fiscale__verify_codice_fiscale"
    ],
    "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 codice-fiscale. 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.
