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.

Changes things 3Claude Code: ask
  • detect_identifierTry every validator for the given country plus the international ones and return the types that accept the value, best first (checksum-bearing types rank above pattern-only ones).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
    Try every validator for the given country plus the international ones and return the types that accept the value, best first (checksum-bearing types rank above pattern-only ones). Use when a document or form field holds a number of unknown type. A match is structural, not proof of type. Example: number '12345678901', country 'KW'. Response: result plus data_confidence (high = check-digit algorithm from a public specification; medium = community-documented checksum or pattern-only; low = structure only), estimated_items[], sources[], data_version and a disclaimer (structural validation only — never proof that an identifier is issued or belongs to someone).

    Annotations the server declares

    • destructiveHint: false
    • idempotentHint: true
    • openWorldHint: false
    • readOnlyHint: true
  • validate_identifierValidate and normalise one identifier whose type you know (format, length, dates and check digits).1 finding

    Why it is in this group

    • The name "validate_identifier" says "validate": a word for reading.
    • 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 "validate_identifier" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

      What this check looks for
    Description, as the server wrote it
    Validate and normalise one identifier whose type you know (format, length, dates and check digits). Returns valid, compact and formatted forms, the checks performed, a reason when invalid, and extracted details where the number encodes them (birth date, sex, holder type). Example: number '784-1990-1234567-1', code 'ae_emirates_id'. Response: result plus data_confidence (high = check-digit algorithm from a public specification; medium = community-documented checksum or pattern-only; low = structure only), estimated_items[], sources[], data_version and a disclaimer (structural validation only — never proof that an identifier is issued or belongs to someone).

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.

Allow the reads, ask before a change or a way out, deny the deletes. Paste into .claude/settings.json.

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 id-format-oracle. 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.
