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

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

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

- **warn** Annotations that disagree with the tool in `generate_uuid_v5` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "generate_uuid_v5" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"idempotentHint":true,"openWorldHint":false}; The name "generate_uuid_v5" says "generate": a word for a change.
```

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

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

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

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

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

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


## Changes things (4)

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

### `generate_nanoid`

- The name "generate_nanoid" 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
Generate URL-safe NanoIDs with an optional size and custom alphabet.
```

### `generate_ulid`

- The name "generate_ulid" 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
Generate monotonic ULIDs (26-character, lexicographically sortable by time).
```

### `generate_uuid`

- The name "generate_uuid" 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
Generate one or more UUIDs. v7 (time-ordered) is best for database keys; v4 is fully random.
```

### `generate_uuid_v5`

- The name "generate_uuid_v5" 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
Deterministic name-based UUID v5 (SHA-1) for a name in a namespace (dns, url, oid, x500 or a UUID).
```

## Only reads (1)

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

### `inspect_uuid`

- The name "inspect_uuid" says "inspect": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Validate a UUID and report its version, variant and embedded timestamp (v1, v6, v7).
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__yoursuuid__inspect_uuid"
    ],
    "ask": [
      "mcp__yoursuuid__generate_uuid",
      "mcp__yoursuuid__generate_uuid_v5",
      "mcp__yoursuuid__generate_ulid",
      "mcp__yoursuuid__generate_nanoid"
    ],
    "deny": []
  }
}
