## 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__map-combiner__combine_map_links` `mcp__map-combiner__list_link_stops` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__map-combiner__combine_map_links` `mcp__map-combiner__list_link_stops` |

## Findings

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

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

annotations: {"readOnlyHint":true,"openWorldHint":true}; The name "combine_map_links" says "link": a word for a change.
```

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

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

annotations: {"readOnlyHint":true,"openWorldHint":true}; The name "list_link_stops" says "list": a word for reading.
```


## Can't be undone (1)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `combine_map_links`

- The name "combine_map_links" says "link": a word for a change.
- The description's first verb is "merge": a word for a change that another call does not undo.
- 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.urls): 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
Merge several Google Maps directions links into one link with all stops in order, to get past the 10-stop limit per route. Short links are expanded. When one route ends where the next starts, the shared stop is kept once.
```

## Changes things (1)

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

### `list_link_stops`

- The name "list_link_stops" says "list": a word for reading.
- The description's first verb is "stop": 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. 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.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
The stops of one Google Maps directions link, in order, as MapCombiner reads them. Use it to check links before combining. For coordinates, distances or CSV/KML export, use MapParser (parseUrl).
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [],
    "ask": [
      "mcp__map-combiner__combine_map_links",
      "mcp__map-combiner__list_link_stops"
    ],
    "deny": []
  }
}
```

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

- `mcp__map-combiner__combine_map_links`: untrusted-input, outbound
- `mcp__map-combiner__list_link_stops`: untrusted-input, outbound
