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.

    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
    Calculates the most a person can contribute for a year given age (on Dec. 31), plans held (401k, 403b, 457b, tsp, simple, ira, hsa_self, hsa_family) and optional wages. Applies the age 50+ catch-up, the SECURE 2.0 age 60-63 super catch-up (eligible only if age 60, 61, 62 or 63 at year end; 64 drops back), the HSA $1,000 catch-up at 55, the shared 402(g) limit across 401(k)/403(b)/TSP/SIMPLE, the separate 457(b) limit, and the compensation cap. With prior_year_fica_wages it tells whether catch-ups must be Roth under SECURE 2.0 section 603 (2026: over $150,000 of 2025 FICA wages).

    Why it is in this group

    • The name "compare_years" says "compare": a word for reading.
    Description, as the server wrote it

Items the IRS has not yet published (2027 plan limits on 2026-11-02) come back as null, never estimated.

Procs. 2027 plan and IRA limits were not yet announced on 2026-11-02 and the tool says so instead of guessing.

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.

Claude Code permissions

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 retirement-contribution-limits-2027. Review it before you use it.

Pin

Keep the decision: fail CI when the tools change, follow every change, or show a badge.
