**3 tools: 3 change things.**

| 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 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__wolfram__WolframLanguageEvaluator` |
| 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 `WolframLanguageEvaluator` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

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

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":false,"openWorldHint":true}; The description's first verb is "evaluate": a word for a change.
```


## Changes things (3)

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

### `WolframAlpha`

- 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 natural language queries with Wolfram|Alpha to get up-to-date computational results about entities in chemistry, physics, geography, history, art, astronomy, and more.
```

### `WolframContext`

- 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
Uses semantic search to retrieve any relevant information from Wolfram.
Always use this tool at the start of new conversations or if the topic changes to ensure you have up-to-date relevant information.
This uses semantic search, so the context argument should be written in natural language (not a search query) and contain as much detail as possible (up to 250 words).
```

### `WolframLanguageEvaluator`

- The description's first verb is "evaluate": a word for a change.
- 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
Evaluates Wolfram Language code for the user in a Wolfram Language kernel.
If a formatted result is provided as a markdown link, use that in your response instead of typing out the output.
Parse natural language input with `\[FreeformPrompt]["query"]`, which is analogous to ctrl+= input in notebooks.
Natural language input is parsed before evaluation, so it works like macro expansion.
You should ALWAYS use this natural language input to obtain things like `Quantity`, `DateObject`, `Entity`, etc.
This is a stateless kernel, so you cannot reuse definitions from previous evaluations.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [],
    "ask": [
      "mcp__wolfram__WolframContext",
      "mcp__wolfram__WolframLanguageEvaluator",
      "mcp__wolfram__WolframAlpha"
    ],
    "deny": []
  }
}
```

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

- `mcp__wolfram__WolframLanguageEvaluator`: untrusted-input

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T14:44:28.667Z, unchanged since 2026-10-22T14:44:28.667Z. 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 | `3` |
| Protocol version | `2025-03-26` |
| 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` |

- **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 3 tools that change things (3 write). Whether a call also works without credentials was not tested: tools are never called.

https://agenttools.wolfram.com/mcp: tools/list returned 3 tools to an anonymous client, including WolframContext (write), WolframLanguageEvaluator (write), WolframAlpha (write)
