## Findings

No check matched anything in these tool definitions.


## Changes things (2)

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

### `buses_from`

- 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
Where intercity buses go from a Thai town, busiest routes first, with departures a day and the lowest fare. From BestBus's nightly data.
```

### `route_info`

- 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 usual daily bus timetable of a Thai route from BestBus's nightly data: departures a day, first and last bus, fare range, journey time, bus companies, boarding points and the route page. No date needed; live seats on a specific date come from search_buses.
```

## Only reads (1)

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

### `search_buses`

- The name "search_buses" says "search": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Live intercity bus departures in Thailand for one route and date, with departure time, bus company, boarding point and lowest fare in Thai baht. Each departure includes a booking_url that opens that bus on bestbus.me, where the traveller chooses seats and pays, and a map link for its boarding point.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__bestbus__search_buses"
    ],
    "ask": [
      "mcp__bestbus__route_info",
      "mcp__bestbus__buses_from"
    ],
    "deny": []
  }
}
```

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

- `mcp__bestbus__search_buses`: untrusted-input
