## 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 (2)

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

### `day_names.for_date`

- 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
Use this when someone gives a date of birth and asks for their Akan or Ghanaian day name (for example "what is my Ghanaian name, I was born on 6 March 1994"), or asks what day name a baby born on a date would have. It works out the weekday itself; do not guess the weekday first. Do not use it for names from other naming traditions, for the meaning of a surname, or for horoscopes.
```

### `day_names.for_weekday`

- 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
Use this when someone already knows the weekday and asks for the Akan day names for it (for example "what are the Akan names for someone born on a Friday"), or asks what weekday an Akan day name such as Kofi or Akosua belongs to. Do not use it when a date of birth is given: use day_names.for_date so the weekday is worked out.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `day-names`:

```json
{
  "permissions": {
    "allow": [],
    "ask": [
      "mcp__day-names__day_names_for_date",
      "mcp__day-names__day_names_for_weekday"
    ],
    "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 2 tools that change things (2 write). Whether a call also works without credentials was not tested: tools are never called.

https://kwekuanansi.ai/mcp/day-names: tools/list returned 2 tools to an anonymous client, including day_names.for_date (write), day_names.for_weekday (write)
