## 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.

### `herbarium.about`

- 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 asks what the Kweku Anansi herbarium is, how many plants it holds, where its records come from or what it leaves out. Do not use it to look up a plant: use herbarium.find or herbarium.card.
```

### `herbarium.card`

- 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 asks what is recorded about one named plant of West or Central Africa: its names, family, warnings, the uses a collector or a desk note recorded, and how many notes are held back. Give the warnings first and say where each row comes from. Do not use it to recommend a remedy, and do not add an amount, how often, how long or a way to prepare one: the herbarium holds such notes back, and a use on record is not evidence that it works or that it is safe.
```

## Only reads (1)

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

### `herbarium.find`

- The name "herbarium.find" says "find": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Use this when someone names a plant of West or Central Africa by its scientific name or a common name (for example "Azadirachta indica", "sobolo" or "prekese") and you need to know whether the Kweku Anansi herbarium has a card for it. It returns the matching cards with family and rank, and says plainly when a plant is not in the herbarium yet. Do not use it to identify a plant from a description or a photograph, or for a plant from outside Africa: it matches names as written, and a plant that is not found may be there under another name.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__herbarium__herbarium_find"
    ],
    "ask": [
      "mcp__herbarium__herbarium_card",
      "mcp__herbarium__herbarium_about"
    ],
    "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/herbarium: tools/list returned 3 tools to an anonymous client, including herbarium.card (write), herbarium.about (write)
