## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data or untrusted-input 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. | none |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

No check matched anything in these tool definitions.


## Changes things (1)

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

### `medicare_part_d_out_of_pocket_cap`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Project month-by-month Medicare Part D out-of-pocket spending against the statutory annual cap, identify the month the cap is reached, quantify what the cap itself saves, and compare normal payment timing against the Medicare Prescription Payment Plan — which spreads the SAME total across the year without reducing it. Supports plan years 2026 and 2027 and fails closed to 2026 for any unsupported year rather than extrapolating. This is a standard-benefit simulation, NOT a plan-specific pharmacy quote: plan negotiated prices and plan cost sharing are not held and are never inferred.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `part-d-cap`:

```json

    ],
    "deny": []
  }
}

- **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 1 tool that changes things (1 write). Whether a call also works without credentials was not tested: tools are never called.

https://insurewith.ai/mcp/part-d-cap: tools/list returned 1 tool to an anonymous client, including medicare_part_d_out_of_pocket_cap (write)
