## Only reads (4)

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

### `compare_plans`

- The name "compare_plans" says "compare": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Compare two to four plans from Wireless Choices side by side on price, data, network or technology, speed, contract and inclusions. Pass the plan type, provider slug and plan slug for each plan, as returned by search_plans.
```

### `get_plan`

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

Description, as the server wrote it:

```untrusted-server-text
Return the details of one plan from Wireless Choices by plan type, provider slug and plan slug, including inclusions, current promotion terms and the link to its detail page. Use the slugs returned by search_plans or list_providers.
```

### `list_providers`

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

Description, as the server wrote it:

```untrusted-server-text
List the telco providers currently listed on Wireless Choices, with the network each one sells access to and how many plans of each type are listed. Use this to resolve a provider name to its slug before calling search_plans or get_plan.
```

### `search_plans`

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

Description, as the server wrote it:

```untrusted-server-text
Search current Australian mobile, prepaid, mobile broadband and nbn home internet plans from providers listed on Wireless Choices. Filter by price, included data, network, speed tier, contract and features. Results are ordered by lowest ongoing price among matching plans and each one carries the date it was last updated on Wireless Choices. Returns up to 10 plans, each with a link to its detail page; use offset for the next plans among the first 50 matches. Use list_providers first if you are unsure which providers exist.
```
