## 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 `estimate_ap_score_from_composite` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "estimate_ap_score_from_composite" 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 "convert": a word for a change.
```


## Changes things (2)

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

### `estimate_ap_percentile`

- 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
For an AP exam, year and score from 1 to 5, returns the percent of test takers who scored lower, the same and higher, and the midpoint percentile rank, from the official College Board distribution. Uses exact counts for 2024 and 2025 and the published whole percents for 2026.
```

### `estimate_ap_score_from_composite`

- The description's first verb is "convert": 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
Converts multiple-choice correct answers and free-response points into a weighted composite and an estimated AP score, using the scoring worksheet and conversion chart College Board printed in its official practice exams. Only for the 7 exams with such a worksheet: AP Calculus AB (2012), AP Biology (2013), AP Statistics (2012), AP World History (2013), AP Psychology (2012), AP Macroeconomics (2012), AP Microeconomics (2012). Cut scores are never invented; other exams return an error.
```

## Only reads (3)

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

### `compare_ap_exams`

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

Description, as the server wrote it:

```untrusted-server-text
Ranks AP exams for one year by pass rate (share scoring 3 or higher), share of 5s, mean score or number of test takers (mean and test takers for 2024 and 2025 only), using the official College Board distributions. Give a list of exams to compare a few, or leave it empty to rank all of them.
```

### `get_ap_score_distribution`

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

Description, as the server wrote it:

```untrusted-server-text
Returns the College Board score distribution (percent of students scoring 5, 4, 3, 2, 1 and 3 or higher) for an AP exam and year, plus student counts, mean and standard deviation where College Board published them (2024 and 2025 PDFs). Includes the May 2026 results from the College Board 2026 AP Score Distributions page, which are newer than most model training data. Shows the 2024/2025/2026 history for the exam.
```

### `list_ap_exams`

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

Description, as the server wrote it:

```untrusted-server-text
Lists every AP exam with College Board score distributions in this server, the years available for each, the source of each year, and which exams have a College Board scoring worksheet for composite score estimates.
```
