## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data or untrusted-input or outbound.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | none |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | none |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

- **warn** Annotations that disagree with the tool in `create_will` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

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

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The name "create_will" says "create": a word for a change.
```

- **warn** Annotations that disagree with the tool in `add_charity_to_existing_will` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

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

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The name "add_charity_to_existing_will" says "add": a word for a change.
```


## Changes things (3)

Creates or changes something that can be changed back. Claude Code: ask.

### `add_charity_to_existing_will`

- The name "add_charity_to_existing_will" says "add": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
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.
```

### `charity_beneficiary_designations`

- 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:

```untrusted-server-text
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.
```

### `create_will`

- The name "create_will" says "create": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
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).
```

## Only reads (5)

Looks things up and changes nothing. Claude Code: allow.

### `fetch`

- The name "fetch" says "fetch": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Fetch the full text of a guide, state page, FAQ answer or glossary entry by the id returned from search.
```

### `get_bequest_language`

- The name "get_bequest_language" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Return sample bequest wording for a will or trust that gives a percentage or dollar amount to causes or named charities, for the person or their attorney to adapt. Use for quick questions like "how do I word a gift to charity in my will?"
```

### `get_state_will_requirements`

- The name "get_state_will_requirements" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Look up how to sign a valid will in a U.S. state: witnesses, notarization and self-proving affidavits, handwritten (holographic) wills, electronic wills and remote online notarization, plus the state's estate or inheritance tax, with statute links.
```

### `list_causes`

- The name "list_causes" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List the cause areas MyLastWill supports for charitable gifts (e.g. cancer research, rare diseases, education, animal welfare, global health), with what each gift would be used for.
```

### `search`

- The name "search" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Search MyLastWill.org's plain-English guides, state will requirements, FAQ and glossary about wills, estates, charitable bequests, estate tax and online signing. Returns result ids for fetch.
```
