## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data 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. | `mcp__social-security-cola-2027__get_social_security_cola` |
| 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 `calculate_cola_increase` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "calculate_cola_increase" 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 description's first verb is "apply": a word for a change.
```


## Changes things (3)

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

### `calculate_claiming_age_benefit`

- 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
Monthly Social Security retirement benefit if claimed at a given age between 62 and 70, from the full-retirement-age amount (PIA). Uses 5/9 of 1 percent a month for the first 36 early months, 5/12 of 1 percent after that, and 2/3 of 1 percent a month of delayed credits for people born after 1942, with SSA dime rounding.
```

### `calculate_cola_increase`

- The description's first verb is "apply": 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
Apply a year's Social Security COLA to a monthly benefit. Rounds down to the next lower 10 cents and shows the whole-dollar payment, as SSA does. Default year 2027 (3.6 percent).
```

### `calculate_earnings_test`

- 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
How much Social Security withholds under the retirement earnings test for a year and annual earnings: $1 for every $2 over the limit, or $1 for every $3 in the year you reach full retirement age.
```

## Only reads (3)

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

### `get_full_retirement_age`

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

Description, as the server wrote it:

```untrusted-server-text
Full retirement age for Social Security from a birth date (20 CFR 404.409, including the January 1 rule and the day-before-birthday rule), the exact date and month it is reached, the earliest month benefits can start at 62 and the percent cut, the spouse percent at 62, delayed retirement credits to age 70 and the survivor full retirement age.
```

### `get_social_security_cola`

- The name "get_social_security_cola" says "get": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Social Security cost-of-living adjustment (COLA) for a payable year, from the SSA "Cost-of-Living Increase and Other Determinations" notice in the Federal Register. The 2027 COLA is 3.6 percent (effective December 2026, paid January 2027, published 2026-10-26). Also returns the COLA history back to 1996. Without a year it checks the Federal Register API for a newer notice.
```

### `get_social_security_limits`

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

Description, as the server wrote it:

```untrusted-server-text
Social Security program amounts for 2023 to 2027 from the Federal Register notices: maximum taxable earnings (2027: $192,300), retirement earnings test limits (2027: $25,560 and $67,920), earnings per work credit, substantial gainful activity, trial work month, maximum federal SSI and PIA bend points.
```
