## 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 (1)

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

### `score_assessment`

- The description's first verb is "run": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Runs the same deterministic rules engine the website uses for one of the assessments and returns the headline, module scores, flags and the plan. No model is involved: the result is computed from published rules, exactly as a visitor to the site would get. Answers: scale questions take 0 to 3 (worst to best anchor) or "dk" for don't know; single-choice questions take the option value; multi-select questions take an array of option values, e.g. {"CTX-markets": ["eu", "uk"]}. Unknown question ids or invalid values are rejected with an error listing them. Unanswered questions lower confidence rather than the score, and the result carries an "evidence" field: with no scored questions answered the headline is "Not enough answers", and below half confidence the headline is marked provisional. The result is a diagnostic to guide a conversation, not advice.
```

## Only reads (5)

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

### `get_article`

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

Description, as the server wrote it:

```untrusted-server-text
The full text of an article or site page by slug, with citation and source labels. About describes stated experience; Services describes the offering; articles describe published views. None is independent verification. Cite the address.
```

### `list_articles`

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

Description, as the server wrote it:

```untrusted-server-text
Catherine Ives-Yim's published articles (slug, title, standfirst, theme, publication label, address, length), optionally filtered by theme or a word in the title. Free to call; no model involved.
```

### `list_assessments`

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

Description, as the server wrote it:

```untrusted-server-text
The free questionnaire tools on the site and, for one of them, its full question set: modules, questions, answer anchors or options, and the conditions under which a question applies. Use this to put the questions to a user before calling score_assessment.
```

### `list_themes`

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

Description, as the server wrote it:

```untrusted-server-text
The themes the articles are grouped under, with counts.
```

### `search_articles`

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

Description, as the server wrote it:

```untrusted-server-text
Keyword search over the bundled writing and site pages. Accepts questions or keywords, excludes further-reading sections, and returns a best passage per source before additional passages. Includes citation and source labels. Read get_article before making broader claims. No model is involved; this is retrieval, not an answer or independent verification.
```

## Claude Code permissions

| Fact | Observed |

| HTTP status of an anonymous initialize | `200` |
| tools/list served without credentials | `yes` |
| Tools that change things, listed without credentials | `1` |

- **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://ianuydptehkpowxqfivq.supabase.co/functions/v1/mcp: tools/list returned 6 tools to an anonymous client, including score_assessment (write)
