## 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__store-canary__check_store` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__store-canary__check_store` |

## Findings

- **warn** Annotations that disagree with the tool in `check_store` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "check_store" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":true}; The name "check_store" says "store": a word for a change.
```


## Changes things (1)

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

### `check_store`

- The name "check_store" says "store": a word for a change.
- 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.
- Tag outbound: The input takes a URL (input.url): a request to a URL can carry data to whoever runs it.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Check a public WooCommerce store from the outside: is it reachable, is HTTPS valid and are redirects sane, is WooCommerce detected, do /cart/ and /checkout/ load, and are payment markers visible on checkout. Read-only: GET requests only, never adds to cart, logs in or submits forms. Returns pass/warn/fail findings plus a link to the full audit.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [],
    "ask": [
      "mcp__store-canary__check_store"
    ],
    "deny": []
  }
}
```

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

- `mcp__store-canary__check_store`: untrusted-input, outbound
