## Findings

No check matched anything in these tool definitions.


## Changes things (1)

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

### `check_coverage`

- 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
Check whether plans cover specific medications (by RxCUI) and have specific doctors in network (by NPI). Use search_drugs and search_doctors first to get the ids.
```

## Only reads (4)

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

### `get_plan`

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

Description, as the server wrote it:

```untrusted-server-text
Full details for one plan: deductible, out-of-pocket max, copays, drug tiers, key benefits, and what the person would pay in the plan's official coverage examples (having a baby, managing diabetes, a simple fracture).
```

### `search_doctors`

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

Description, as the server wrote it:

```untrusted-server-text
Look up a doctor near a ZIP code to get their NPI, needed by check_coverage.
```

### `search_drugs`

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

Description, as the server wrote it:

```untrusted-server-text
Look up a medication by name (generic or brand) to get its RxCUI, needed by check_coverage. Pick the entry matching the strength and form the person takes.
```

### `search_plans`

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

Description, as the server wrote it:

```untrusted-server-text
Find ACA Marketplace plans for a household, with the premium tax credit applied and plans ranked by estimated total yearly cost. Also reports the monthly tax credit, cost-sharing reduction (extra-savings Silver) eligibility and likely Medicaid eligibility.
```
