| Group | Class | Tools | Claude Code |
| --- | --- | --- | --- |

| Only reads | read | 2 | allow |

## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data or outbound.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | none |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__appealmyclaim__draft_appeal_letter` `mcp__appealmyclaim__explain_denial_code` `mcp__appealmyclaim__get_appeal_deadlines` `mcp__appealmyclaim__get_appeal_rights` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

- **warn** Annotations that disagree with the tool in `explain_denial_code` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "explain_denial_code" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":true}; The name "explain_denial_code" says "explain": a word for reading.
```


## Changes things (2)

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

### `draft_appeal_letter`

- 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.
- 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
Draft an appeal letter for the user to review and send. For requests like "my insurer denied my MRI as not medically necessary, help me appeal" or "write an appeal letter for an out-of-network denial". Returns a letter as plain text with [brackets] for anything not given, a checklist of what to attach (denial notice, doctor's letter of medical necessity, records), and tips. It never sends or files anything.
```

### `explain_denial_code`

- The name "explain_denial_code" says "explain": a word for reading.
- The input takes a statement or command to run (input.code), which can change anything it can reach.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Explain the denial codes on an Explanation of Benefits. For requests like "my EOB says CO-50, what does that mean?", "what is denial code PR 204?" or "what does N130 mean?". Returns each code in plain words, who usually fixes it (the provider's billing office, an appeal, or the user), whether the provider can bill the user for it (from the group code CO, PR, OA or PI), and a letter link when an appeal fits.
```

## Only reads (2)

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

### `get_appeal_deadlines`

- The name "get_appeal_deadlines" says "get": 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
How long someone has to appeal, and how fast the plan must decide. For requests like "how long do I have to appeal?", "when is my appeal due?" or "how fast does my insurer have to answer?". With the date on the denial notice, gives an approximate file-by date. The date on the user's own notice is the one that counts.
```

### `get_appeal_rights`

- The name "get_appeal_rights" says "get": 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
Appeal rights, steps and free help for a plan type and state. For requests like "what are my appeal rights in California?", "my insurer denied my claim, what can I do?" or "how do Medicare appeals work?". Returns who decides, the steps (internal appeal, external review, Medicare levels or Medicaid fair hearing), deadlines, and where to get free help, including the state insurance department. If the plan type is not known, leave it out to get the rules for most private plans.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__appealmyclaim__get_appeal_rights",
      "mcp__appealmyclaim__get_appeal_deadlines"
    ],
    "ask": [
      "mcp__appealmyclaim__explain_denial_code",
      "mcp__appealmyclaim__draft_appeal_letter"
    ],
    "deny": []
  }
}
```

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

- `mcp__appealmyclaim__get_appeal_rights`: untrusted-input
- `mcp__appealmyclaim__get_appeal_deadlines`: untrusted-input
- `mcp__appealmyclaim__explain_denial_code`: untrusted-input
- `mcp__appealmyclaim__draft_appeal_letter`: untrusted-input

- **warn** Tools that change things, listed to anyone ([unauth-remote-writes](https://anlyon.dev/methodology#unauth-remote-writes))

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 2 tools that change things (2 write). Whether a call also works without credentials was not tested: tools are never called.

https://goodturn-mcp.pages.dev/appealmyclaim/mcp: tools/list returned 4 tools to an anonymous client, including explain_denial_code (write), draft_appeal_letter (write)
```
