## 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__events__search_events` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__events__get_event` `mcp__events__list_hubs` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Only reads (5)

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

### `get_day_overview`

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

Description, as the server wrote it:

```untrusted-server-text
How busy one day is in a hub of mygn.de (Hamburg, München, Oldenburg + Umland) and rundown.city (San Francisco): the number of events per category, how many are free, how many have a verified location, whether the day is quiet, normal or busy compared with the same kind of day (weekday or weekend) in the next 14 days (unknown for a day further out, where the listings are not complete yet) and top_curated, our editorial picks of the day (occurrence_id, title, starts_at; empty while nothing is rated). Events are counted once per day however many time slots they have. Use it to answer 'is there a lot on this Saturday' before listing events with search_events.
```

### `get_event`

- The name "get_event" says "get": a word for reading.
- Tag untrusted-input: The description's first sentence says "url": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
The full record of one event occurrence from search_events, in a hub of mygn.de (Hamburg, München, Oldenburg + Umland) and rundown.city (San Francisco): summary, start and end time, venue with address and coordinates, price text, age_min, the audience block (family, adults_only, visitor_pick, family_p as in search_events; null when not rated), the organiser's link (url), the link to this event's own page on our site or, without one, our hub page (share_url), brand (mygn or rundown) and attribution_url (the hub page to cite as the source), plus the next 20 other dates of the same event (siblings, with siblings_truncated true when there are more). Internal fields (signals, series_kind, kind, title_override) are left out unless verbose is true. all_day true means the occurrence spans the whole day (T00:00 start, ends_at at least 18 hours later). time_unknown true means starts_at is only a date anchor, not a start time: never show 00:00. series_continues true means the listed dates of this recurring event stop only where our sources' look-ahead stops, so it likely runs on: never say it ends after the last listed date. Use url for the organiser's page, where tickets and opening details are.
```

### `list_categories`

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

Description, as the server wrote it:

```untrusted-server-text
List the event categories one hub of mygn.de (Hamburg, München, Oldenburg + Umland) and rundown.city (San Francisco) currently has, each with its slug, display label (in the hub's language) and a one-line definition. The slugs are the values for the categories filter of search_events. Typical slugs: party, concert, culture, show, family, food, sport, market, cruise, quiz, tours, other; an event has exactly one.
```

### `list_hubs`

- The name "list_hubs" says "list": a word for reading.
- Tag untrusted-input: The description's first sentence says "list" and "website": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
List the cities (hubs) covered by mygn.de (Hamburg, München, Oldenburg + Umland) and rundown.city (San Francisco): hub slug, display label, timezone and the website of the hub. Pass the slug as hub to the other tools. The hub website is the source to cite.
```

### `search_events`

- The name "search_events" says "search": a word for reading.
- Tag private-data: The description's first sentence says "search" and "calendar": it reads calendars.
- Findings: info long-description

Description, as the server wrote it:

```untrusted-server-text
Search upcoming events in one hub of mygn.de (Hamburg, München, Oldenburg + Umland) and rundown.city (San Francisco) between date_from and date_to in the hub's local calendar. Returns a compact list in time order with at most 50 events per call (default 25); follow next_cursor for more. An event that runs several times on one day (for example 11:00, 13:00 and 15:00) is ONE item whose starts_at and occurrence_id are those of its first slot and whose slots list gives occurrence_id, starts_at and ends_at of every slot; total and paging count items. Each item has occurrence_id, title, display_title, category, starts_at (local time), all_day, time_unknown, venue, is_free, price_text (in the hub's language and currency), attend_mode, share_url (the event's own page on our site or, without one, our hub page, the source to cite), age_min (a stated minimum age, null when the source states none, 0 for all ages), the audience block and tags. The audience block is null when the event is not rated; otherwise family (true: suitable for parents with children, false: not, null: unsure), adults_only (true: an adults-only event, false: not, null: unsure), visitor_pick (0 to 1, how much a first-time visitor would be glad to find it; a ranking hint, not a filter) and family_p (0 to 1, the raw family-friendly probability behind family, for your own threshold). query matches each word on its own in the title and summary (all words first, any word if none has them all; German compounds such as Halloweenparty are split); the words Kinder, Kids, Familie and family do not filter but list family events first, then the rest, each group in the requested sort. time_from and time_to (HH:MM, hub local time) keep the events that start in that range, for 'tonight' or 'in the morning'. Internal fields (editorial score and flags, signals, series_kind, kind, long_running) are left out unless verbose is true. Examples: 'free events this weekend' -> free_only with the weekend dates; 'something for kids on Saturday' -> categories=['family'] for that day; 'concerts tonight' -> categories=['concert'] and time_from='18:00' for today. all_day true means the occurrence spans the whole day (starts_at is the day anchor T00:00 and it ends at least 18 hours later). time_unknown true means starts_at is only a date anchor because no showtime is known: never show 00:00, say the time is not given. Call get_event for the details of events you will mention.
```
