## Findings

No check matched anything in these tool definitions.


## Changes things (3)

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

### `destination_facts`

- 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
Facts about a travel destination (a city or region) from the AlgoTrips destination guides: country, a short overview, what the full guide covers, and links to the guide and to plan a trip there when available. If the place is not found, it names close matches to try instead.
```

### `my_trips`

- 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 signed-in AlgoTrips account's 10 most recent trips, newest first: title, cities, dates, status and a link to open each one on AlgoTrips. Needs the person to be signed in to AlgoTrips.
```

### `plan_trip`

- Nothing in its name or description says what it does, so it is counted as a write.
- 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
Builds a full day-by-day trip with live prices in the signed-in AlgoTrips account: flights from the home city (unless gettingAround is none), hotels, activities and transfers for each city, for the cities, start date, travellers and home city given. The kind of hotel (hotelStars) and what the travellers enjoy (interests) shape the hotels and activities picked. A field name the tool does not take is refused: nothing is built, and the answer names the right field. Returns a build id at once. The trip takes about 3 to 6 minutes, and AlgoTrips emails the person when it is ready (the price and the link), or if it could not build it, when it has their email (the answer says so). With choicesConfirmed not true and any of the budget, the kind of hotel, pace, activities, getting around or (2 or more cities) the city order left out, nothing is built: the answer lists those choices with their questions and defaults. Booking and payment happen on algotrips.com. Needs the person to be signed in to AlgoTrips.
```

## Only reads (1)

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

### `trip_status`

- The name "trip_status" says "status": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
How a trip build is going, by its build id: while it builds, what it is working on; when it is ready, the total price, nights, hotel (with its star rating and guest score out of 10) and number of activities per city, the order of the cities and why when AlgoTrips changed it, a day-by-day outline with the flights, and the link to open and book it on AlgoTrips. Needs the person to be signed in.
```

## Claude Code permissions

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

    ],
    "ask": [
      "mcp__algotrips__destination_facts",
      "mcp__algotrips__my_trips",
      "mcp__algotrips__plan_trip"
    ],
    "deny": []
  }
}
```
