**7 tools: 1 do something that can't be undone, 3 change things and 3 only read.**

| Group | Class | Tools | Claude Code |
| --- | --- | --- | --- |
| Deletes or cancels | destructive | 0 | deny |
| Can't be undone | irreversible | 1 | ask |
| Changes things | write | 3 | ask |
| Only reads | read | 3 | allow |

## 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__workouts__report_workout` |

## Findings

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

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

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


## Can't be undone (1)

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

### `report_workout`

- The description's first verb is "send": a word for sending, and what is sent cannot be taken back.
- Tag outbound: The description's first verb is "send": it sends or publishes something to other people.

Description, as the server wrote it:

```untrusted-server-text
Send Goblin Gains what the user thinks of a workout from these tools.
    Call it whenever the user points out a mistake (wrong equipment, a weight,
    a dose that cannot fit) or says a workout is bad or good: the words go to
    Goblin Gains, nothing else about the user does.
```

## Changes things (3)

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

### `generate_workouts`

- The name "generate_workouts" says "generate": 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
New workouts unlike any in the library, from our generator (no AI),
    as text: evolved from the library's workouts and movements (more lines,
    fewer, other formats) into kinds it does not hold. For one person.
    Nothing is saved; other ones each call. suggest_workouts and
    vary_workout stay close to library workouts instead.

    A shortfall says what blocked it.
```

### `suggest_workouts`

- 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
New workouts from our generator, as text. Ask this instead of writing
    workouts yourself. Nothing is saved.

    Example, two people with an echo bike, rower and ski erg, 40-60 min:
    suggest_workouts(count=5, people=2, minutes_min=40, minutes_max=60,
    equipment=["echo-bike", "row-ergometer", "ski-erg"], bodyweight=False)

    A shortfall says what blocked it.
```

### `vary_workout`

- 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
Variations of one library workout from our generator (no AI), as
    text, in its own format or another. Nothing is saved.

    A shortfall says what blocked it.
```

## Only reads (3)

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

### `find_movements`

- The name "find_movements" says "find": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Movement slugs whose name holds `query` (e.g. "row", "sled"), for
    suggest_workouts' include and exclude, machines and runs first.
```

### `list_archetypes`

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

Description, as the server wrote it:

```untrusted-server-text
The workout archetypes the generator makes, one per line: key, name,
    formats, minutes, line count, and the session slots it serves.
```

### `list_equipment`

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

Description, as the server wrote it:

```untrusted-server-text
The equipment suggest_workouts' `equipment` takes, one per line:
    key: name, with "(machine)" on ergometers (rower, ski erg, bikes).
    Keys, names and common names ("echo", "row erg", "DB", "kb") all work.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `workouts`:

```json
{
  "permissions": {
    "allow": [
      "mcp__workouts__list_archetypes",
      "mcp__workouts__list_equipment",
      "mcp__workouts__find_movements"
    ],
    "ask": [
      "mcp__workouts__suggest_workouts",
      "mcp__workouts__vary_workout",
      "mcp__workouts__generate_workouts",
      "mcp__workouts__report_workout"
    ],
    "deny": []
  }
}
```

Capability tags behind the rules (a read tagged outbound is asked about):

- `mcp__workouts__report_workout`: outbound

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-11-02T00:18:43.359Z, unchanged since 2026-11-02T00:18:43.359Z. No credentials were sent and no tool was called. Values are shown as the endpoint returned them. Method: https://anlyon.dev/methodology#remote-posture

| Fact | Observed |
| --- | --- |
| Reachable | `yes` |
| HTTP status of an anonymous initialize | `200` |
| tools/list served without credentials | `yes` |
| Tools that change things, listed without credentials | `4` |
| Protocol version | `2025-06-18` |
| WWW-Authenticate on 401 | `not observed` |
| resource_metadata in WWW-Authenticate | `none` |
| RFC 9728 protected resource metadata | `none` |
| Authorization servers | `none` |
| Legacy HTTP+SSE transport | `no` |
| Dynamic client registration | `not observed` |
| Client ID metadata documents | `not observed` |

- **high** Tools that change things, listed to anyone ([unauth-remote-writes](https://anlyon.dev/methodology#unauth-remote-writes))

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 4 tools that change things (1 irreversible, 3 write). Whether a call also works without credentials was not tested: tools are never called.

https://api.goblingains.com/mcp: tools/list returned 7 tools to an anonymous client, including report_workout (irreversible), suggest_workouts (write), vary_workout (write), generate_workouts (write)
