## 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__sparkads__get_my_stats` `mcp__sparkads__get_slot` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__sparkads__update_creative` |

## Findings

No check matched anything in these tool definitions.


## Changes things (1)

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

### `update_creative`

- The name "update_creative" says "update": a word for a change.
- Tag outbound: The input takes a URL (input.url): a request to a URL can carry data to whoever runs it.

Description, as the server wrote it:

```untrusted-server-text
Edit this advertiser's ad card. Pass only the fields to change; anything omitted keeps its current value. WRITE TOOL, and it costs something: saving resets the card's status to 'pending', so the ad STOPS running until a person approves it again. Say that to the user and get their agreement before calling this. Caps: name 40 characters, tagline 60, one-sentence body 160, url must be https, domain must be a bare hostname like myapp.com. House style: plain words, no exclamation marks, and the sentence says what the product does rather than why it is good.
```

## Only reads (4)

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

### `get_my_stats`

- The name "get_my_stats" says "get": a word for reading.
- Tag untrusted-input: The description's first sentence says "get" and "review": it reads comments, which other people can write.

Description, as the server wrote it:

```untrusted-server-text
Get this advertiser's own ad performance for the last 30 days: impressions and clicks split by day, by app in the Spark network, and by traffic source, plus every creative they own with its review status. Read-only. Scoped to the API key holder; it cannot report on anyone else.
```

### `get_network_pulse`

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

Description, as the server wrote it:

```untrusted-server-text
Get the whole network's last 24 hours: total impressions, total clicks, how many apps showed the carousel, and how many of the 24 hourly slots are taken. This is the public inventory figure, the same one the SparkAds landing page prints, not this advertiser's own numbers. Read-only.
```

### `get_slot`

- The name "get_slot" says "get": a word for reading.
- Tag untrusted-input: The description's first sentence says "get" and "review": it reads comments, which other people can write.

Description, as the server wrote it:

```untrusted-server-text
Get the hour this advertiser holds: the UTC hour, the same hour on their target country's clock, the country itself, and the card that runs in it with its review status. Also reports whether the ad is actually live right now, which needs all three of a held hour, an approved card and a paying subscription. Read-only.
```

### `list_free_slots`

- The name "list_free_slots" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List the UTC hours nobody has claimed yet, out of the 24 the network sells. Pass a country to also get each free hour on that country's clock and the best five ranked by local evening attention. Supported countries: GB, IE, PT, FR, DE, ES, IT, NL, BE, SE, NO, DK, PL, CH, AT, NG, FI, GR, RO, UA, EG, ZA, IL, SA, TR, RU, KE, AE, PK, IN, BD, TH, VN, ID, CN, SG, MY, PH, HK, TW, AU, JP, KR, NZ, BR, AR, US, CA, PE, CO, MX. Read-only; claiming an hour still happens on the website.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__sparkads__get_my_stats",
      "mcp__sparkads__get_slot",
      "mcp__sparkads__list_free_slots",
      "mcp__sparkads__get_network_pulse"
    ],
    "ask": [
      "mcp__sparkads__update_creative"
    ],
    "deny": []
  }
}
```

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

- `mcp__sparkads__get_my_stats`: untrusted-input
- `mcp__sparkads__get_slot`: untrusted-input
- `mcp__sparkads__update_creative`: outbound

- **warn** Tools that change things, listed to anyone ([unauth-remote-writes](https://anlyon.dev/methodology#unauth-remote-writes))

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 1 tool that changes things (1 write). Whether a call also works without credentials was not tested: tools are never called.

https://sparkads.dev/api/mcp/mcp: tools/list returned 5 tools to an anonymous client, including update_creative (write)
