## Exfil surface

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

| 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__catalog__read_surface` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__catalog__read_surface` |

## Findings

No check matched anything in these tool definitions.


## Only reads (2)

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

### `local_search`

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

Description, as the server wrote it:

```untrusted-server-text
Semantic search over The Network catalog. Returns skill entities ranked by embedding similarity.
```

### `read_surface`

- The name "read_surface" says "read": a word for reading.
- Tag untrusted-input: The description's first sentence says "read" and "web": 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
Read an external web surface, discovery-first: returns its WebMCP/MCP server-card manifest when one exists; otherwise DOM-dehydrates the page into an indexed interactive-element text map (static parse, truth_class=inferred).
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__catalog__local_search"
    ],
    "ask": [
      "mcp__catalog__read_surface"
    ],
    "deny": []
  }
}
```

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

- `mcp__catalog__read_surface`: untrusted-input, outbound
