| Group | Class | Tools | Claude Code |

## Exfil surface

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

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__ahook__get_event` `mcp__ahook__list_events` `mcp__ahook__wait_for_event` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__ahook__create_inbox` `mcp__ahook__list_events` `mcp__ahook__wait_for_event` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

No check matched anything in these tool definitions.


## Deletes or cancels (1)

Removes, cancels or revokes something. Claude Code: deny.

### `delete_inbox`

- The name "delete_inbox" says "delete": a word for removing or ending something.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Delete an inbox and its events. Auth: Authorization Bearer read token header.
```

## Changes things (2)

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

### `create_inbox`

- The name "create_inbox" says "create": a word for a change.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Create a webhook inbox. Returns its ingest URL and a read token (shown once).
```

### `extract_field`

- 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
Pull a JSON path out of an event body. Auth: Authorization Bearer read token header.
```

## Only reads (3)

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

### `get_event`

- The name "get_event" says "get": a word for reading.
- Tag private-data: The input names an inbox (input.inbox_id), and the tool reads: it reads mail.

Description, as the server wrote it:

```untrusted-server-text
Get one event by id. Auth: Authorization Bearer read token header.
```

### `list_events`

- The name "list_events" says "list": a word for reading.
- Tag private-data: The description's first sentence says "list" and "inbox": it reads mail. The input names an inbox (input.inbox_id), and the tool reads: it reads mail.
- Tag untrusted-input: The description's first sentence says "list" and "inbox": it reads inbound email, which other people can write.

Description, as the server wrote it:

```untrusted-server-text
List events in an inbox. Auth: Authorization Bearer read token header.
```

### `wait_for_event`

- The name "wait_for_event" says "wait": a word for reading.
- Tag private-data: The description's first sentence says "wait" and "inbox": it reads mail. The input names an inbox (input.inbox_id), and the tool reads: it reads mail.
- Tag untrusted-input: The description's first sentence says "wait" and "inbox": it reads inbound email, which other people can write.

Description, as the server wrote it:

```untrusted-server-text
Wait for the next event in an inbox after a cursor, up to 30s. Auth: Authorization Bearer read token header.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__ahook__wait_for_event",
      "mcp__ahook__list_events",
      "mcp__ahook__get_event"
    ],
    "ask": [
      "mcp__ahook__create_inbox",
      "mcp__ahook__extract_field"
    ],
    "deny": [
      "mcp__ahook__delete_inbox"
    ]
  }
}
```

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

- `mcp__ahook__create_inbox`: untrusted-input
- `mcp__ahook__wait_for_event`: private-data, untrusted-input
- `mcp__ahook__list_events`: private-data, untrusted-input
- `mcp__ahook__get_event`: private-data
