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.

Description, as the server wrote it
Draft a codicil (a short signed amendment) that adds a charitable gift to a will the person already has, plus gift wording to give their attorney. Use when someone already has a will and wants to leave a percentage or dollar amount to causes or charities. Not legal advice; for Louisiana and North Carolina residents only the gift wording is returned.

Description, as the server wrote it
Prepare instructions for naming charities as beneficiaries of retirement accounts, life insurance, bank (payable-on-death) or brokerage (transfer-on-death) accounts, with the percentages to write on each form. No will needed. Traditional IRAs and 401(k)s are often the most tax-efficient assets to leave to charity. Charities must be named specifically.

  What this check looks for
Description, as the server wrote it
Draft a complete U.S. last will and testament, optionally with charitable gifts to causes the person chooses. Use when someone wants to make, write or update a will. Interview the person first and pass only facts they gave you; never invent names. Returns the will text, a state-specific signing checklist, a plain-English summary of who inherits, and warnings to resolve before signing. Not legal advice; wills are not produced for Louisiana or North Carolina residents (gift wording is returned instead).

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.

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 mylastwill. Review it before you use it.

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