## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data or untrusted-input 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. | none |
| 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.


## Deletes or cancels (1)

Removes, cancels or revokes something. Claude Code: deny.

### `update_map`

- The name "update_map" says "update": a word for a change.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Change a map made with create_map when the person asks for changes, keeping its link: anyone who has the link sees the change, and it keeps working another hour. Send the whole changed map document, not just what changed: it replaces the map. Fails once someone has added the map to their account.
```

## Changes things (1)

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

### `create_map`

- The name "create_map" says "create": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Make a web map of places, routes or areas, and get a link anyone can open to see it, with no code and no account. Write it as the map document get_map_spec describes. The link works for an hour after the map last changed; opening it, the person can add the map to their squidmaps account to keep it, publish it and share it for good. Returns an id and editToken: keep them, to change this map with update_map rather than making another.
```

## Only reads (2)

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

### `get_map_spec`

- The name "get_map_spec" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Read this first when someone wants a map: of places, a route or an area, or of data like a CSV or GeoJSON, to look at or to share with a link. It's how squidmaps maps are written: GeoJSON features, how they're styled, and their popups, title panel and legend. Then make the map with create_map.
```

### `preview_map`

- The name "preview_map" says "preview": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
A picture of a map made with create_map, as people who open its link see it, to check it before you share the link: where things are, their styles, its title panel and legend. 1200×630 by default, the shape most people see it in. Ask for another size to fit the map's shape: taller (like 800×1000) for a map that runs north to south, wider (like 1000×600) for one that runs east to west. The picture shows what fits on a screen that size, so a larger one shows more of a large map. At most 1,000,000 pixels (width × height).
```
