## 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.


## Only reads (3)

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

### `get_case`

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

Description, as the server wrote it:

```untrusted-server-text
One case: its dated spread timeline (seed, first amplifier, platform jumps, press, peak), Spread Score and citation. Fields that need sign-in come back locked, with the case URL where the full record is.
```

### `list_mechanics`

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

Description, as the server wrote it:

```untrusted-server-text
The closed vocabulary of spread mechanics, each defined, with how many cases use it.
```

### `search_cases`

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

Description, as the server wrote it:

```untrusted-server-text
Search the How It Spread library of viral cases (films, products, memes, campaigns) by text, kind, mechanic or platform. Returns each case's Spread Score, dates, platforms, mechanics, an image URL and the case URL to cite.
```

## Claude Code permissions
