## 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__agvps__vps-medium` `mcp__agvps__vps-medium-renew` `mcp__agvps__vps-small` `mcp__agvps__vps-small-renew` |
| 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.


## Changes things (5)

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

### `feedback`

- 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
Free. Tell the people who run this service what worked, what failed or what you miss: a bug, an idea or a thanks. A person reads it. No payment, no account; limited to a few messages an hour.
```

### `vps-medium`

- 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.
- 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
Rent a Linux server for a month and get root access: 2 vCPU, 2 GB RAM, 25 GB NVMe, a dedicated IPv4 address, Ubuntu 24.04, in Germany or Finland. Pay per month in stablecoins with x402 or MPP, no account and no card. The answer carries a server id and secret; the IP and the root password follow in about 5 to 10 minutes. Extend it with the renew route.
```

### `vps-medium-renew`

- 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.
- 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
Extend a medium server by one to six months. Send the server id from the order and the number of months; each month is billed at the plan's monthly price. Pay in stablecoins with x402 or MPP. The server keeps its data and its IP. A server that is not renewed stops at its expiry date. Use the renew route that matches the server's plan.
```

### `vps-small`

- 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.
- 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
Rent a Linux server for a month and get root access: 1 vCPU, 1 GB RAM, 10 GB NVMe, a dedicated IPv4 address, Ubuntu 24.04, in Germany or Finland. Pay per month in stablecoins with x402 or MPP, no account and no card. The answer carries a server id and secret; the IP and the root password follow in about 5 to 10 minutes. Extend it with the renew route.
```

### `vps-small-renew`

- 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.
- 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
Extend a small server by one to six months. Send the server id from the order and the number of months; each month is billed at the plan's monthly price. Pay in stablecoins with x402 or MPP. The server keeps its data and its IP. A server that is not renewed stops at its expiry date. Use the renew route that matches the server's plan.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [],
    "ask": [
      "mcp__agvps__vps-small",
      "mcp__agvps__vps-small-renew",
      "mcp__agvps__vps-medium",
      "mcp__agvps__vps-medium-renew",
      "mcp__agvps__feedback"
    ],
    "deny": []
  }
}
```

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

- `mcp__agvps__vps-small`: untrusted-input
- `mcp__agvps__vps-small-renew`: untrusted-input
- `mcp__agvps__vps-medium`: untrusted-input
- `mcp__agvps__vps-medium-renew`: untrusted-input

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T15:18:51.304Z, unchanged since 2026-10-22T15:18:51.304Z. No credentials were sent and no tool was called. Values are shown as the endpoint returned them. Method: https://anlyon.dev/methodology#remote-posture

| Fact | Observed |

| HTTP status of an anonymous initialize | `200` |

- **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 5 tools that change things (5 write). Whether a call also works without credentials was not tested: tools are never called.

https://agvps.shveik.dev/mcp: tools/list returned 5 tools to an anonymous client, including vps-small (write), vps-small-renew (write), vps-medium (write), vps-medium-renew (write), feedback (write)
