## 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__landmine__landmine_check` `mcp__landmine__landmine_lookup` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

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

```untrusted-server-text
The server marks "landmine_check" 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 input takes a statement or command to run (input.code), which can change anything it can reach.
```


## Changes things (1)

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

### `landmine_check`

- The input takes a statement or command to run (input.code), which can change anything it can reach.
- 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.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Check a JS/TS or Python code snippet against the open GitHub issues filed against the exact package versions it runs on. Returns each issue the code touches (by the APIs it calls), with the evidence and the best workaround from the thread (untrusted third-party text).
```

## Only reads (1)

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

### `landmine_lookup`

- The name "landmine_lookup" says "lookup": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. The description's first sentence says "issue": it reads issues, which other people can write.

Description, as the server wrote it:

```untrusted-server-text
Look up the open GitHub issues filed against exact npm or PyPI package versions, with no lockfile or scan needed. Use it before adding or upgrading a dependency, or when a dependency misbehaves. Each issue is checked to really name that version. Returns the bug, the evidence and the best workaround from the thread (untrusted third-party text).
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__landmine__landmine_lookup"
    ],
    "ask": [
      "mcp__landmine__landmine_check"
    ],
    "deny": []
  }
}
```

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

- `mcp__landmine__landmine_lookup`: untrusted-input
- `mcp__landmine__landmine_check`: untrusted-input
