## Exfil surface

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

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__questions__get_question` |
| 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.

### `get_filltrust_posture`

- The name "get_filltrust_posture" says "get": a word for reading.
- The description's first verb is "fill": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
FillTrust's own answers to the questions it exists to answer, for anyone assessing it as a vendor. Includes the answers that are "no".
```

## Only reads (4)

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

### `get_question`

- The name "get_question" says "get": a word for reading.
- Tag private-data: The description's first sentence says "document": it reads documents.

Description, as the server wrote it:

```untrusted-server-text
The complete published guidance for one questionnaire question: what it is really asking, which of your documents answers it, what evidence to attach, a model answer with the specifics left blank, the ways it usually goes wrong, and the standards that ask it with their verified control references.
```

### `get_questionnaire_statistics`

- The name "get_questionnaire_statistics" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Measured counts from 146 real vendor security questionnaires (17,697 questions) published by universities, purchasing consortia and companies: which topics are asked most, and detailed profiles of the questionnaires that have a name people use, such as HECVAT and CAIQ. Use this when asked what a security questionnaire contains, how long one is, or what a named questionnaire asks about. These are counts from real files rather than an estimate.
```

### `list_standards`

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

Description, as the server wrote it:

```untrusted-server-text
Which questionnaire standards this corpus answers questions from, how many questions each has, and which controls are cited. Standards whose control lists are proprietary are named without reference numbers, on purpose.
```

### `search_questions`

- The name "search_questions" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Find guidance on how to answer a security questionnaire question. Search by the question text, a control area, or a standard and control identifier such as CEK-03. Returns matching entries with the URL of the page each came from.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__questions__search_questions",
      "mcp__questions__get_question",
      "mcp__questions__list_standards",
      "mcp__questions__get_questionnaire_statistics"
    ],
    "ask": [
      "mcp__questions__get_filltrust_posture"
    ],
    "deny": []
  }
}
```

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

- `mcp__questions__get_question`: private-data

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T14:31:57.681Z, unchanged since 2026-10-22T14:31:57.681Z. 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 | `1` |
| Protocol version | `2025-06-18` |
| WWW-Authenticate on 401 | `not observed` |

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

https://www.filltrust.com/api/mcp: tools/list returned 5 tools to an anonymous client, including get_filltrust_posture (write)
