## Exfil surface

1 private-data -> untrusted-input -> outbound path in this server alone. Denying 1 outbound tool breaks every one: `mcp__trust-scan__read_skill`.

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

| Private data | Untrusted input | Outbound |
| --- | --- | --- |
| `mcp__trust-scan__read_skill` | `mcp__trust-scan__read_skill` | `mcp__trust-scan__read_skill` |

## Findings

No check matched anything in these tool definitions.


## Changes things (2)

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

### `trust_scan_file`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Security-scan a single file for invisible Unicode, dangerous patterns, and secrets.

Returns a severity-weighted score and per-finding detail (rule, severity,
location). Read-only: the file is never modified.
```

### `trust_scan_server`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Security-scan an MCP server or skill package before trusting it.

Runs all four checks — invisible Unicode prompt-injection, dangerous code
patterns (MCP001–006), hardcoded secrets, typosquat package names — and
returns a 0-100 score, letter grade, and detailed findings. Run this on
any directory BEFORE wiring it into your agent. Read-only: never modifies
the scanned target.
```

## Only reads (2)

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

### `read_skill`

- The name "read_skill" says "read": a word for reading.
- Tag private-data: The description's first sentence says "read" and "file": it reads files.
- Tag untrusted-input: The description's first sentence says "read" and "uri": it reads web pages, which anyone can write. The input takes a URL (input.uri), and the tool reads it: it reads web pages, which anyone can write.
- Tag outbound: The input takes a URL (input.uri): 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 a product skill file by its skill:// URI.
```

### `skills_list_tool`

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

Description, as the server wrote it:

```untrusted-server-text
List this product's skills. Each entry carries the SKILL.md URI,
its name and description, verbatim frontmatter, and a per-file
sha256 manifest. Read a body with `read_skill`.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `trust-scan`:

```json
{
  "permissions": {
    "allow": [
      "mcp__trust-scan__skills_list_tool"
    ],
    "ask": [
      "mcp__trust-scan__trust_scan_server",
      "mcp__trust-scan__trust_scan_file",
      "mcp__trust-scan__read_skill"
    ],
    "deny": []
  }
}
```

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

- `mcp__trust-scan__read_skill`: private-data, untrusted-input, outbound
