## Findings

- **warn** Annotations that disagree with the tool in `start_reservation` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

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

annotations: {"readOnlyHint":true}; The name "start_reservation" says "start": a word for a change.
```

- **warn** Annotations that disagree with the tool in `map_url` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

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

annotations: {"readOnlyHint":true}; The description's first verb is "open": a word for a change.
```


## Changes things (2)

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

### `map_url`

- The description's first verb is "open": 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
OpenMapp map link for a city search, optionally with a gym drawer already open.
```

### `start_reservation`

- The name "start_reservation" says "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
Check that a class at a gym can be reserved online right now and get the link where the visitor signs the gym's waiver and pays (or reserves free). Returns the class's next date and start time, price, cancellation policy, and reserveUrl. It does not book anything: the visitor must open reserveUrl and sign and pay themselves. When status is unavailable, reason says why and reservableClasses lists classes that can be reserved instead.
```

## Only reads (3)

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

### `find_gyms`

- The name "find_gyms" says "find": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Find BJJ gyms near a US city, neighborhood, or ZIP. Defaults: open to drop-ins, classes today. Returns drop-in policy, visitor fee when known, matching class times, and online booking (reservePrice, reserveUrl) when the gym takes reservations.
```

### `get_gym`

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

Description, as the server wrote it:

```untrusted-server-text
Full public gym card: address, drop-in policy, visitor fee, the weekly timetable, and online booking when the gym takes reservations (price and reserveUrl per class). Use an id or slug from find_gyms.
```

### `list_cities`

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

Description, as the server wrote it:

```untrusted-server-text
US cities OpenMapp covers, with gym counts, how many welcome class drop-ins, and how many list an open mat. Use this to check coverage before find_gyms. Filter by city name or two-letter state.
```
