## 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__events__get-event` |
| 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

No check matched anything in these tool definitions.


## Changes things (1)

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

### `featured-events`

- 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 events Events.Aero is featuring right now, the same selection as the lead row of the home page, optionally for one country. Each includes its public event page URL.
```

## Only reads (4)

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 description's first sentence says "get" and "contact": it reads contacts.

Description, as the server wrote it:

```untrusted-server-text
Get one public event by its sqid or slug (from search-events or featured-events): dates, venue, price, how to book or RSVP, organiser contact details shown on the event page, flying in (PPR, runway, landing fees and whether pilots can RSVP to fly in), the day's schedule and the description. Always share the event page URL.
```

### `list-countries`

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

Description, as the server wrote it:

```untrusted-server-text
The countries Events.Aero lists events in, with the code to pass to other tools and each country's public home and events pages.
```

### `list-event-types`

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

Description, as the server wrote it:

```untrusted-server-text
The kinds of aviation event on Events.Aero (airshow, fly-in, workshop and so on), with the value to pass to search-events and the public page that lists each type in a country.
```

### `search-events`

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

Description, as the server wrote it:

```untrusted-server-text
Search upcoming public aviation events on Events.Aero (airshows, fly-ins, workshops and more). Filter by free text, event type, country, date range, distance from a point, free entry or online events. Results are ordered by start date, or by distance when latitude and longitude are given, one page at a time. Every result includes the public event page URL: send people there to book or RSVP.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__events__search-events",
      "mcp__events__get-event",
      "mcp__events__list-event-types",
      "mcp__events__list-countries"
    ],
    "ask": [
      "mcp__events__featured-events"
    ],
    "deny": []
  }
}
```

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