**3 tools: 2 do something that can't be undone and 1 only read.**

| Group | Class | Tools | Claude Code |

## Exfil surface

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

| 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. | `mcp__toolalize__convert_currency` `mcp__toolalize__convert_units` |

## Findings

No check matched anything in these tool definitions.


## Can't be undone (2)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `convert_currency`

- The name "convert_currency" says "convert": a word for a change.
- The input addresses people (input.to): what it sends cannot be taken back.
- Tag outbound: The input takes a destination (input.to): what the tool writes goes there.

Description, as the server wrote it:

```untrusted-server-text
Convert an amount between currencies using LIVE exchange rates (refreshed every 6h). Use ISO 4217 codes (USD, EUR, ...). This is the tool to use instead of estimating rates from memory.
```

### `convert_units`

- The name "convert_units" says "convert": a word for a change.
- The input addresses people (input.to): what it sends cannot be taken back.
- Tag outbound: The input takes a destination (input.to): what the tool writes goes there.

Description, as the server wrote it:

```untrusted-server-text
Convert a numeric value between two units of the same category (length, weight, volume, temperature, etc.). Units resolve by id or symbol (e.g. "cm" or "centimeter"). For currency use convert_currency.
```

## Only reads (1)

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

### `list_units`

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

Description, as the server wrote it:

```untrusted-server-text
List every conversion category with its units (id, symbol, name). Call this to discover the vocabulary before convert_units.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__toolalize__list_units"
    ],
    "ask": [
      "mcp__toolalize__convert_units",
      "mcp__toolalize__convert_currency"
    ],
    "deny": []
  }
}
```

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

- `mcp__toolalize__convert_units`: outbound
- `mcp__toolalize__convert_currency`: outbound

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T14:55:18.929Z, unchanged since 2026-10-22T14:55:18.929Z. No credentials were sent and no tool was called. Values are shown as the endpoint returned them. Method: https://anlyon.dev/methodology#remote-posture

| Fact | Observed |
| --- | --- |
| Reachable | `yes` |
| HTTP status of an anonymous initialize | `200` |
| tools/list served without credentials | `yes` |
| Tools that change things, listed without credentials | `2` |
| Protocol version | `2025-06-18` |
| WWW-Authenticate on 401 | `not observed` |
| resource_metadata in WWW-Authenticate | `none` |
| RFC 9728 protected resource metadata | `none` |
| Authorization servers | `none` |
| Legacy HTTP+SSE transport | `no` |
| Dynamic client registration | `not observed` |
| Client ID metadata documents | `not observed` |

- **high** 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 irreversible). Whether a call also works without credentials was not tested: tools are never called.

https://toolalize.com/mcp: tools/list returned 3 tools to an anonymous client, including convert_units (irreversible), convert_currency (irreversible)
