## Exfil surface

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

| 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__workoutx__get_endpoint_reference` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__workoutx__get_endpoint_reference` |

## Findings

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

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

annotations: {"readOnlyHint":true,"openWorldHint":false}; The name "generate_workout" says "generate": a word for a change.
```

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

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

annotations: {"readOnlyHint":true,"openWorldHint":false}; The name "generate_program" says "generate": a word for a change.
```

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

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

annotations: {"readOnlyHint":true,"openWorldHint":false}; The name "generate_types" says "generate": a word for a change.
```

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

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

## Changes things (7)

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

### `check_api_key`

- 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:

Only reads the text; never sends the request. Uses one request.
```

### `estimate_calories`

- 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.

Calories burned for an exercise from its MET value, body weight and duration.
```

### `export_exercise_seed`

- 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

```

### `get_endpoint_reference`

- The name "get_endpoint_reference" says "get": a word for reading.
- Tag untrusted-input: The input takes a URL (input.endpoint), and the tool reads it: it reads web pages, which anyone can write.

```

### `get_usage_stats`

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

Description, as the server wrote it:

```untrusted-server-text
Your account's API usage: requests, success rate, response times (avg and p95), errors by status code, top endpoints, daily counts, live quota, rate limit and media-limit usage. Use it to answer "why am I getting 429s?" or "when will my quota run out?". Uses one request.
