## Findings

No check matched anything in these tool definitions.


## Changes things (2)

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

### `appeal_deadline`

- 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
Calendar arithmetic for Medicare Advantage appeal deadlines. Give notice_date (the date printed on the plan’s denial notice) for the plan reconsideration deadline: 65 days from that date (the rule is 60 days from receipt, presumed 5 days after the date). Or give care_end_date (the date covered skilled nursing, home health or outpatient rehab care ends, on the Notice of Medicare Non-Coverage) for the fast appeal: by noon the day before. The notice’s own instructions come first.
```

### `claim_back_services`

- 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
How Claim Back helps with a Medicare Advantage appeal and what it costs: a free check of the denial letter, then two fixed-price services (we handle it for you, paid only if the decision is reversed; or we prepare it and you send it). Returns the link where the user uploads their letter. Use it when the user wants help with an appeal or asks about Claim Back.
```

## Only reads (2)

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

### `list_guides`

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

Description, as the server wrote it:

```untrusted-server-text
Lists Claim Back’s guides to appealing a Medicare Advantage denial (US), each with its slug, title, one-line summary and link: how to appeal and who can ask, the appeal deadline, the fast appeal when care is ending, and the independent review. Use it to find the guide that answers the user’s question, then read_guide.
```

### `read_guide`

- The name "read_guide" says "read": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Returns one guide in full as Markdown, with its sources (the federal regulations, Medicare.gov and CMS). Use it to answer questions about Medicare Advantage appeals accurately, and link the guide in the answer.
```
