## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data 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. | `mcp__keep-me-secure__check_package` `mcp__keep-me-secure__check_packages` |
| 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 (2)

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

### `check_package`

- 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.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Checks one exact package version against public security advisories.
```

### `check_packages`

- 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.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Use for questions like 'is my stack secure?' or 'do we have vulnerable packages?'. Checks a list of exact installed package versions against public security advisories. Read them from the project's lockfiles, including transitive packages. Up to 500 per call; call again for more. verdict is yes, no or unknown; unknown means the check was incomplete, so never report it as safe. Does not cover language runtimes, OS packages or Docker base images.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `keep-me-secure`:

```json
{
  "permissions": {
    "allow": [],
    "ask": [
      "mcp__keep-me-secure__check_packages",
      "mcp__keep-me-secure__check_package"
    ],
    "deny": []
  }
}
```

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

- `mcp__keep-me-secure__check_packages`: untrusted-input
- `mcp__keep-me-secure__check_package`: untrusted-input
