## 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__maps__map_setup` |
| 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 `privacy_area_map` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

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

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The description's first verb is "show": a word for reading.
```


## Can't be undone (1)

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

### `privacy_area_map`

- The description's first verb is "show": a word for reading.
- The description says "cannot be recovered".
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Show roughly where a place is without revealing the exact point. The point is snapped to a grid and drawn as a shaded circle that always contains the true point, with no pin; every address in the same grid cell gets the identical image, so the exact location cannot be recovered or averaged out across listings. Use it for real-estate, rental and marketplace listings, people's homes, or any location that should stay private. The image is returned inline, with a reusable URL that contains only the snapped point. Counts 1 static image against the account's monthly cap.
```

## Changes things (2)

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

### `geocode`

- 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
Look up an address, place name or point of interest and get coordinates (lat, lon), a readable label and address parts, from OpenStreetMap data. Use it before static_map or privacy_area_map when you only have an address. Counts 1 address lookup against the account's monthly cap. Results may be stored: up to 30 days on the Free plan, indefinitely on paid plans. Show "© OpenStreetMap contributors" with results.
```

### `static_map`

- 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
Render a map as an image (returned inline) with optional pins (markers) and a line (path, e.g. a route). Give center and zoom, or just markers and/or path and the view is fitted automatically. Also returns a reusable image URL for web pages (add your key). Counts 1 static image against the account's monthly cap. Do not use this to show a private address such as someone's home; use privacy_area_map instead.
```

## Only reads (2)

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

### `map_setup`

- The description's first verb is "get": a word for reading.
- Tag untrusted-input: The description's first sentence says "get" and "html": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
Get ready-to-paste HTML/JavaScript for an interactive, zoomable PinSharing map in a web page (MapLibre GL JS vector map, Leaflet or OpenLayers raster map), or the raster tile URL template for any other library. Replace YOUR_KEY with a key restricted to the website. Needs no key and uses no quota; the map itself counts map tiles when viewed.
```

### `reverse_geocode`

- The description's first verb is "find": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Find the nearest address or place to a latitude/longitude, from OpenStreetMap data. Counts 1 address lookup against the account's monthly cap. Same storage terms and attribution as geocode.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__maps__reverse_geocode",
      "mcp__maps__map_setup"
    ],
    "ask": [
      "mcp__maps__geocode",
      "mcp__maps__static_map",
      "mcp__maps__privacy_area_map"
    ],
    "deny": []
  }
}
```

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

- `mcp__maps__map_setup`: untrusted-input
