## Exfil surface

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

| 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. | `mcp__estate-gift-tax-exemption-calculator__check_gift` |

## Findings

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

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

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The input addresses people (input.recipients): what it sends cannot be taken back.
```


## Can't be undone (1)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `check_gift`

- The input addresses people (input.recipients): what it sends cannot be taken back.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag outbound: The input takes a destination (input.recipients): what the tool writes goes there.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Checks a gift against the federal gift tax rules for a year (2013-2026): annual exclusion per recipient ($19,000 in 2025 and 2026), gift splitting with a spouse (sec. 2513, doubles it to $38,000), unlimited marital deduction for a US citizen spouse, and the separate annual exclusion for a non-citizen spouse ($190,000 in 2025, $194,000 in 2026 under Rev. Procs. 2024-40 and 2025-32). Returns taxable gifts, whether Form 709 is required, lifetime exemption used and left (2026: $15,000,000), and any gift tax due.
```

## Changes things (1)

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

### `calculate_estate_tax`

- 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
Calculates US federal estate tax the Form 706 way: taxable estate (gross estate minus deductions such as debts, expenses, marital and charitable bequests), plus adjusted taxable gifts, tentative tax on the unified rate schedule of 26 USC 2001(c) (18% to 40%), minus gift tax payable, minus the applicable credit on the basic exclusion amount plus any DSUE (portability) from a deceased spouse. Years 2013-2026. Uses $15,000,000 for 2026 deaths (P.L. 119-21), $13,990,000 for 2025. Federal only.
```

## Only reads (2)

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

### `compare_years`

- The name "compare_years" says "compare": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Compares two years (2013-2026) side by side: basic exclusion amount, applicable credit, annual gift exclusion and non-citizen spouse exclusion, and, with a taxable estate, the federal estate tax in each year. Default 2025 vs 2026, the year P.L. 119-21 raised the exemption to $15,000,000 instead of letting it fall to about half.
```

### `get_exemption_amounts`

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

Description, as the server wrote it:

```untrusted-server-text
Returns the federal basic exclusion amount (estate and lifetime gift tax exemption), the applicable credit, the filing threshold, the annual gift exclusion per recipient (and doubled with gift splitting), the annual exclusion for gifts to a non-citizen spouse, the 2026 GST exemption and the 40% top rate. Years 2011-2026 from the IRS. 2026: $15,000,000 under P.L. 119-21 (One Big Beautiful Bill Act) sec. 70106, NOT the scheduled TCJA sunset to about half; 2025: $13,990,000; 2026 annual exclusion $19,000; non-citizen spouse $194,000 (Rev. Proc. 2025-32). Models trained before mid-2025 often predict the sunset.
```
