## Exfil surface

3 private-data -> untrusted-input -> outbound paths in this server alone. Denying 1 outbound tool breaks every one: `mcp__reverse-engineer-anything_supermarioworld__fetch_generic_url_content`.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__reverse-engineer-anything_supermarioworld__fetch_docs` `mcp__reverse-engineer-anything_supermarioworld__search_code` `mcp__reverse-engineer-anything_supermarioworld__search_docs` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__reverse-engineer-anything_supermarioworld__fetch_generic_url_content` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__reverse-engineer-anything_supermarioworld__fetch_generic_url_content` |

## Findings

No check matched anything in these tool definitions.


## Only reads (4)

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

### `fetch_docs`

- The name "fetch_docs" says "fetch": a word for reading.
- Tag private-data: The name "fetch_docs" says "fetch" and "doc": it reads documents. The description's first sentence says "fetch" and "file": it reads files.

Description, as the server wrote it:

```untrusted-server-text
Fetch entire documentation file from GitHub repository: ethanhunt1981/reverse-engineer-anything_supermarioworld. Useful for general questions. Always call this tool first if asked about ethanhunt1981/reverse-engineer-anything_supermarioworld.
```

### `fetch_generic_url_content`

- The name "fetch_generic_url_content" says "fetch": a word for reading.
- Tag untrusted-input: The name "fetch_generic_url_content" says "fetch" and "url": it reads web pages, which anyone can write. The description's first sentence says "url": it reads web pages, which anyone can write. The input takes a URL (input.url), and the tool reads it: it reads web pages, which anyone can write.
- Tag outbound: The input takes a URL (input.url): a request to a URL can carry data to whoever runs it.
- Claude Code: ask, because it is tagged outbound.

Description, as the server wrote it:

```untrusted-server-text
Generic tool to fetch content from any absolute URL, respecting robots.txt rules. Use this to retrieve referenced urls (absolute urls) that were mentioned in previously fetched documentation.
```

### `search_code`

- The name "search_code" says "search": a word for reading.
- Tag private-data: The description's first sentence says "search" and "repository": it reads repositories.

Description, as the server wrote it:

```untrusted-server-text
Search for code within the GitHub repository: "ethanhunt1981/reverse-engineer-anything_supermarioworld" using the GitHub Search API (exact match). Returns matching files for you to query further if relevant.
```

### `search_docs`

- The name "search_docs" says "search": a word for reading.
- Tag private-data: The name "search_docs" says "search" and "doc": it reads documents. The description's first sentence says "repository": it reads repositories.
