## Exfil surface

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

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__boxing__fetch` |
| 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 `boxing_schedule` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "boxing_schedule" 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 "boxing_schedule" says "schedule": a word for a change.
```


## Changes things (7)

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

### `bout`

- 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
One bout in full by Boxerbook bout id: both boxers with records going in, status, result (winner, method, round, time), start_utc, venue, card, broadcasters, sources, Boxerbook forecast with its signals and the market consensus when known. Cite the url.
```

### `boxer`

- 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
One boxer's card by name, slug or Boxerbook id: country, division, record (W-L-D, KOs), stance, height, reach, birth date, nickname, next fight, last result, Boxerbook rating and, when known, the record as betting favourite and underdog. A name goes through the site search and returns the best match (other_matches lists the next ones: check them when the name is common). Cite the url.
```

### `boxing_results`

- 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
Completed professional bouts of the last N days (N calendar days ending today: 1 = today, 2 = last night and today, up to 14), newest first: winner, method, round, time, both records going in and the sources of each result. Use this for "who won last night", "results this weekend". Cite the url of each bout.
```

### `boxing_schedule`

- The name "boxing_schedule" says "schedule": 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
Upcoming professional boxing cards worldwide, grouped by card: date, start_utc (card start in UTC), venue, promoter, broadcasters, and each bout with both records going in, division, scheduled rounds, title, Boxerbook forecast and market consensus when known. Use this for "who is fighting tonight / this weekend", "what boxing is on". when=today also keeps last night's cards that started under 6 hours ago. Cite the url of each card or bout.
```

### `next_fight`

- 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
A boxer's next scheduled bout (by name, slug or id): date, start_utc (card start in UTC), opponent, venue, broadcasters, Boxerbook forecast and market consensus when known; next_fight is null when none is on record (last_result is then the latest bout). Cite the url.
```

### `rankings`

- 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
The top 15 of a division: the Boxerbook rating (default) or the latest list of a publisher (WBC, WBA, IBF, WBO, The Ring, TBRB), with records. Division by code (hea, wel, w_fea) or name (heavyweight, women's flyweight). Cite the url.
```

### `where_to_watch`

- 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
The broadcasters (platform, region, link) of a bout or of a whole card, with the card start time in UTC. Give bout_id or event_id. An empty list means none is on record yet. Cite the url.
```

## Only reads (3)

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

### `fetch`

- The name "fetch" says "fetch": a word for reading.
- Tag private-data: The description's first sentence says "document": it reads documents.

Description, as the server wrote it:

```untrusted-server-text
The full document for an id returned by search: a boxer card, a bout (records, result, broadcasters, forecast, market, sources), a card with its bouts, or a division's rankings, as Markdown text with metadata. Pass the id unchanged; an unknown id returns an error. Cite the url.
```

### `search`

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

Description, as the server wrote it:

```untrusted-server-text
Search the whole catalog with one query: boxers by name, bouts by two surnames ("Inoue vs Nakatani"), their cards, and divisions ("heavyweight rankings"); an id such as bout:123 is looked up directly. Each hit has an id for fetch, a title and its boxerbook.com url; ChatGPT connectors and deep research, which call nothing but search and fetch, start here. No match returns an empty list. Cite the url.
```

### `search_boxers`

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

Description, as the server wrote it:

```untrusted-server-text
Find boxers by name (at most 20), best match first: id, slug, name, country, division, record. Use this when a name is ambiguous or its spelling unsure, then call boxer or next_fight with the id. Cite the url.
```
