## 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__spam-i-am__request_approval` `mcp__spam-i-am__start_check` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__spam-i-am__start_check` |

## Findings

No check matched anything in these tool definitions.


## Changes things (2)

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

### `request_approval`

- The name "request_approval" says "request": a word for a change.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Get a link (approve_url) for your human to open: they sign in, add funds if needed, set a spending limit and approve. Show them the link, then call get_approval. Use this when a check is refused with free_check_used, insufficient_funds or key_limit.
```

### `start_check`

- The name "start_check" says "start": a word for a change.
- 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.webhook_url): a request to a URL can carry data to whoever runs it.

Description, as the server wrote it:

```untrusted-server-text
Start a check of what AT&T, Verizon and T-Mobile phones show when a number calls. Returns the test line to call ('dial') for each carrier and a check id (and a token for a keyless check: keep it). The number being checked must then call each test line within the window. The first check on a number is free; later ones need a key with funds.
```

## Only reads (4)

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

### `get_approval`

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

Description, as the server wrote it:

```untrusted-server-text
Status of an approval request: pending, approved, declined or expired. Once approved, a keyless request returns api_key (shown once): pass it as api_key to the other tools. Set wait_seconds (up to 25) to wait for a decision.
```

### `get_balance`

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

Description, as the server wrote it:

```untrusted-server-text
Needs a key. The account balance, holds, and this key's spending limit.
```

### `get_check`

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

Description, as the server wrote it:

```untrusted-server-text
The check and each carrier's result: status waiting, complete or incomplete; the label shown and caller name; flagged true/false; a screenshot link. Set wait_seconds (up to 25) to wait for results to arrive before answering.
```

### `get_coverage`

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

Description, as the server wrote it:

```untrusted-server-text
Which carriers are online now, prices in cents, and the dialing window.
```

      "mcp__spam-i-am__request_approval"
    ],
    "deny": []
  }
}
```
