## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data 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. | `mcp__opplevagent__book_gardssalg` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

- **info** Long descriptions in `book_gardssalg` ([long-description](https://anlyon.dev/methodology#long-description))

```untrusted-server-text
The description is 2,512 characters long, over the 2,000 this check looks for.

description ends: "...fredag', party_size 4, guest_name 'Kari Nordmann', guest_email 'kari@example.no'."
```


## Deletes or cancels (1)

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

### `book_gardssalg`

- The description's first verb is "submit": a word for a change.
- The server marks it destructive (destructiveHint: true).
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Findings: info long-description

Description, as the server wrote it:

```untrusted-server-text
Submit a booking REQUEST for a Norwegian gårdssalg (farm-sale) producer discovered via discover_gardssalg. Send inn en reservasjonsforespørsel for et gårdssalg-besøk. IMPORTANT: this NEVER creates a confirmed booking — it creates a PENDING request, exactly like the producer's own website form. The PRODUCER reviews the request and responds (confirms, proposes another time, or declines); guest_email only receives a read-only status link, never anything that can finalize the booking. No payment is involved (pickup/visit, pay on arrival, as today). Only producers with an active booking status (see discover_gardssalg's booking.live field) can be booked — a paused/not-yet-onboarded producer is rejected with a clear message, never a silent failure. VIKTIG: oppretter ALDRI en bekreftet booking — kun en avventende forespørsel; produsenten mottar forespørselen og svarer (bekrefter, foreslår nytt tidspunkt eller avslår). ONE-SENTENCE FLOW («book et møte hos X fredag 20. oktober kl. 10 for 4 personer»): call this ONCE with provider_query='X' (the producer's name — no discover_gardssalg round-trip needed), slot_at, party_size, guest_name, guest_email and requested_weekday='fredag'. The tool resolves X to exactly one producer (or returns candidates / not-found with NO booking created), checks that the date really is a Friday (or returns weekday_mismatch:true with the nearest Fridays, NO booking created), then submits the request and notifies the producer by email. guest_name and guest_email are the HUMAN guest's own — ask the guest for them if you do not have them; never invent or reuse someone else's. Required: provider_id OR provider_query, slot_at (requested date/time, 'YYYY-MM-DDTHH:MM' Europe/Oslo), party_size, guest_name, guest_email. Optional: requested_weekday, experience_id, guest_phone, notes, confirm_outside_hours. The requested slot_at is ALWAYS hard-rejected if it's in the past or too far ahead. If the producer has stated opening hours and slot_at falls outside them, this returns outside_hours:true (not an error) instead of creating the booking — retry once with confirm_outside_hours:true if the exact requested time should be kept anyway. On success the response carries the resolved producer (provider.navn) and slot_at_local (e.g. 'fredag 23. oktober 2026 kl. 10:00') — read both back to the guest. Example: provider_query 'Fjordgard Bryggeri', slot_at '2026-10-23T10:00', requested_weekday 'fredag', party_size 4, guest_name 'Kari Nordmann', guest_email 'kari@example.no'.
```

## Only reads (4)

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

### `discover_experiences`

- The description's first verb is "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Search the opplevagent.no curated marketplace of Norwegian experiences and activities. Filtrer på fylke (county), kategori, vær, sesong, innendørs/utendørs, gruppestørrelse, pris og varighet. / Filter by county, category, weather, season, indoor/outdoor, group size, price, and duration. Also supports near-me search via lat/lng (+ optional radius_km): when given, results include a rounded distance_km and a geo_precision flag ('address' = exact, 'kommune' = approximate municipality centroid) and are sorted nearest-first. Returns title, category, location (fylke/kommune), description, and booking URL if available. Only verified experiences from active providers (Brreg-checked) are returned. Covers Norway only: pass the user's request in `query`; for a place outside Norway (e.g. Kenya) the tool returns no experiences, and the answer is that Opplevagent only covers Norway. Food-product shopping such as buying stockfish is outside this tool's scope. Pass that intent in query; an out_of_scope response must not be retried as a general discovery search. Examples: 'hva kan vi finne på i Troms om vinteren?' (fylke='Troms', season='winter'), 'wildlife experiences' (category='dyreliv_safari'), 'outdoor activities in Oslo for 4 people', 'experiences within 50km of lat 69.65 / lng 18.95'.
```

### `discover_gardssalg`

- The description's first verb is "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Search opplevagent.no's gårdssalg (farm-sale) vertical — Brreg-registered Norwegian drink producers (bryggeri/cideri/vingård/destilleri/gårdskafé/mjød/seltzeri) selling directly from the farm. Finn norske gårdssalg-produsenter (drikkeprodusenter som selger direkte fra gården) etter fylke, kommune og produsenttype. / Filter by county (fylke), municipality (kommune), and producer type. Also supports near-me search via lat/lng (+ optional radius_km): when given, results include a rounded distance_km and are sorted nearest-first, and rows with no geocoded location are excluded (never a fabricated distance). Returns id (the provider_id for book_gardssalg), name, location, producer type, profile_url, and an honest booking status (live direct booking vs. a dark-launch 'coming soon' note — never overclaims booking availability). Include each returned producer's profile_url as a clickable link when available; when booking is paused, tell the user to contact the producer via that profile page. To look up ONE specific producer by name (e.g. when the guest says 'book hos Fjordgard Bryggeri'), pass `query`. Examples: 'gårdssalg i Vestland', 'cideri near lat 60.4 / lng 5.3', 'bryggeri med booking', query: 'Fjordgard Bryggeri'.
```

### `get_experience`

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

Description, as the server wrote it:

```untrusted-server-text
Fetch complete details for a single experience from opplevagent.no by its UUID. Henter fullstendig informasjon om en opplevelse via UUID. Returns title, full description, category, location (fylke/kommune/meeting point), indoor/outdoor, season, weather suitability, group size limits, age suitability, price, duration, languages, booking URL, and booking type. Obtain the UUID from discover_experiences results. Example: id 'a1b2c3d4-e5f6-7890-abcd-ef1234567890'.
```

### `list_experience_categories`

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

Description, as the server wrote it:

```untrusted-server-text
List all experience categories available on opplevagent.no, along with the number of verified experiences in each category. Henter alle kategorier med antall verifiserte opplevelser. Use this to understand what kinds of experiences are available before calling discover_experiences with a specific category filter. Example question: 'hvilke typer opplevelser finnes i Norge?', 'what categories are available?'.
```

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

https://opplevagent.no/mcp: tools/list returned 5 tools to an anonymous client, including book_gardssalg (destructive)
