```


## Changes things (3)

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

### `buy_changepacket_calls`

- The name "buy_changepacket_calls" says "call": a word for a change.
- Findings: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
Use only when free usage is exhausted or persistent production use is needed. Returns a Stripe checkout URL for 2,000 prepaid ChangePacket calls for $9; it does not itself charge or expose payment credentials.
```

### `check_mcp_surface_changes`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Use when an agent depends on a remote public HTTPS MCP server and needs to know whether its tool catalog changed. First call stores the tools/list baseline; later calls return only added, removed, or modified tools plus compact risk hints. Avoid for private/authenticated MCP endpoints or as a substitute for a full security audit.
```

### `check_url_changes`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Use for repeated research on one public webpage when the agent only needs what changed since its last call. First call stores a baseline; later calls return added/removed text lines. Avoid for authenticated/private pages, binary files, or one-time page reading.
```
