## 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__salon-decisions__get_booking_link` `mcp__salon-decisions__get_merchant` |
| 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 `compare_options` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

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

annotations: {"readOnlyHint":true,"idempotentHint":true,"openWorldHint":false}; The name "compare_options" says "compare": a word for reading.
```


## Changes things (2)

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

### `check_availability`

- 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
Published facts for one salon, NOT live availability and NOT an extras-inclusive quote. For a service/budget/extras/date decision use compare_options with salon=ref. For one salon (ref from search_merchants) and a date: published opening hours on that date (open/closed — NOT live appointment slots), offerings matching the service with published prices and durations, the booking link and step-by-step booking instructions. Profiled salons add candidate start times (candidate start times from the salon's published staff schedule; existing bookings are not subtracted, so some may already be taken — confirm on the booking page). Same contract as GET /api/v1/availability?ref=.
```

### `compare_options`

- The name "compare_options" says "compare": a word for reading.
- The description's first verb is "start": 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
START HERE for choosing a service under a budget, with extras, or on a date. Use search_merchants for name/address lookup; use this tool for the service decision. Compare a supported service intent, optional budget/date/neighborhood, strict or nearby geography, and selected add-ons (blow_dry, haircut, toner, shampoo, deep_conditioning, iron_finish, extensions). Returns options, uncertain and excluded service decisions with per-fact sources/dates, known subtotal including requested/mandatory extras, unresolved charges, explicit conditions, hours conflicts and exact next actions. Starting prices and required consultations never become guaranteed final quotes. Deposit is advance payment, not an added charge. There is no provider-confirmed availability; date-specific results are conditional. Time-of-day, stylist and hair-length requirements are unsupported filters here; retain them for merchant confirmation. Ordering is geographic/alphabetic, not a quality rating. No booking or hold is created. Paginated: limit <= 50, offset; use next_offset across all three result groups.
```

## Only reads (8)

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

### `get_availability`

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

Description, as the server wrote it:

```untrusted-server-text
NOT live availability. Use compare_options for budget/extras/date decisions. Candidate start times for one offering at one salon, optionally one stylist and a date/time window: candidate start times from the salon's published staff schedule; existing bookings are not subtracted, so some may already be taken — confirm on the booking page. Results carry slotBasis "schedule_candidates" and bookingsSubtracted false; freshness tells you how old the capture is.
```

### `get_booking_link`

- The name "get_booking_link" 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 salon's own booking URL plus exact remaining steps for a given service, stylist, and start time. This site never books on the user's behalf; precision says how much the link pre-selects.
```

### `get_merchant`

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

Description, as the server wrote it:

```untrusted-server-text
All published facts for one salon by ref "<city>/<vertical>/<slug>" (from search results), with crawl_log (every source fetched or checked, with time, result and the facts it gave) and last_verified_at: address, phone, hours, licence, registry, services with published prices, booking link, per-field sources (verification), what we verified and what we did not.
```

### `get_salon`

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

Description, as the server wrote it:

```untrusted-server-text
Full record for one salon as markdown: facts, hours, every haircut service with price/duration/inclusions, stylists, policies, attributes, evidence, booking rules, candidate start times from the published schedule. Every fact carries a status tag and date.
```

### `get_stylist`

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

Description, as the server wrote it:

```untrusted-server-text
One stylist, under the name the salon's booking system shows: salon, bookable status, specialty evidence with sources, services and prices, candidate start times from the published schedule, and booking link.
```

### `list_salons`

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

Description, as the server wrote it:

```untrusted-server-text
Salons covered (San Francisco), ordered profiled, detailed, then listed, with depth, neighborhood, price floor and range, stylist count, availability basis and freshness, last_verified_at and verification date. Paginated: limit (default 50, max 200), offset, depth=profiled|detailed|listed.
```

### `search_haircuts`

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

Description, as the server wrote it:

```untrusted-server-text
Base offering lookup by haircut type, length or stylist. Use compare_options for a supported service with budget, extras or date; preserve any unsupported stylist/length/time requirements for merchant confirmation. Find haircut offerings (and optionally stylists and candidate start times) that satisfy ALL given constraints, across profiled salons (hand-normalized menus) and listed salons (type and inclusions inferred from the service name; offering.comparable says whether it can be compared apples-to-apples). Start times are candidate start times from the salon's published staff schedule; existing bookings are not subtracted, so some may already be taken — confirm on the booking page (slotBasis "schedule_candidates", bookingsSubtracted false, availability_basis "schedule_candidates" = UNCONFIRMED). require_availability=true is satisfied only by provider-confirmed availability (the booking provider’s own open times, existing bookings subtracted). No salon on this site has provider-confirmed availability today: profiled salons have candidate start times from the published staff schedule (existing bookings not subtracted, so they may already be taken) and listed salons have published opening hours only. Offerings with matching candidate start times are listed under `unconfirmed`; confirm on the booking page. Hard constraints are never relaxed silently; when nothing matches, noMatch.reason explains which constraint blocked and nearest suggests the smallest change. Prices are published menu or online-booking prices in USD; this search does not add requested or mandatory extras. Times are salon-local (America/Los_Angeles).
```

### `search_merchants`

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

Description, as the server wrote it:

```untrusted-server-text
Discovery and name/address lookup, not an extras-inclusive price decision. For a supported service with budget, extras or date, start with compare_options. Find San Francisco hair salons and barbers by name/street (q), neighborhood (with nearby), service, date/time and online booking. Returns compact task summaries by default: depth (profiled = researched in depth; listed = public records + the business’s own site, see depth_note), booking_cta, hours_for_day (published hours for `date`, not live slots), up to 3 matched_offerings with prices, license_status, freshness, availability_basis (published_hours / schedule_candidates = unconfirmed / none); profiled salons add candidate_start_times. Unknown values are null. For published hours/detail only, call check_availability. Before selecting a budget option, call compare_options; follow next_action to confirm unresolved charges and actual appointment availability with the merchant.
```
