## 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__agents__extract_web_data` `mcp__agents__read_web_page` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__agents__check_ai_visibility` `mcp__agents__extract_web_data` `mcp__agents__make_marketing_video` `mcp__agents__read_web_page` |

## Findings

No check matched anything in these tool definitions.


## Changes things (4)

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

### `check_ai_visibility`

- Nothing in its name or description says what it does, so it is counted as a write.
- 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
Check whether AI answer-engines recommend a brand: 0-100 score, competitors winning, GEO fix-list. Paid: $4 USDC via x402.
```

### `extract_web_data`

- Nothing in its name or description says what it does, so it is counted as a write.
- Tag untrusted-input: The description's first sentence says "scrape": it reads web pages, which anyone can write.
- 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
Scrape a public URL into the exact structured JSON you ask for (prices, contacts, listings, specs). Paid: $0.05 USDC via x402.
```

### `make_marketing_video`

- Nothing in its name or description says what it does, so it is counted as a write.
- 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
Produce a finished, on-brand short marketing video from one prompt. Paid: $12 USDC via x402.
```

### `verify_output`

- 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
Verify another agent's deliverable is real + meets spec before you pay for it. Paid: $1 USDC via x402.
```

## Only reads (2)

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

### `list_vevang_agents`

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

Description, as the server wrote it:

```untrusted-server-text
List Vevang's live autonomous AI agents — what they do, prices, and endpoints.
```

### `read_web_page`

- The name "read_web_page" says "read": a word for reading.
- Tag untrusted-input: The name "read_web_page" says "read" and "web": it reads web pages, which anyone can write. The description's first sentence says "read" and "url": it reads web pages, which anyone can write. The input takes a URL (input.url), and the tool reads it: it reads web pages, which anyone can write.
- Tag outbound: The input takes a URL (input.url): a request to a URL can carry data to whoever runs it.
- Claude Code: ask, because it is tagged outbound.

Description, as the server wrote it:

```untrusted-server-text
Read any public URL as clean, LLM-ready markdown (main content + title + links). Paid: $0.01 USDC via x402.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__agents__list_vevang_agents"
    ],
    "ask": [
      "mcp__agents__make_marketing_video",
      "mcp__agents__check_ai_visibility",
      "mcp__agents__verify_output",
      "mcp__agents__read_web_page",
      "mcp__agents__extract_web_data"
    ],
    "deny": []
  }
}
```

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

- `mcp__agents__make_marketing_video`: outbound
- `mcp__agents__check_ai_visibility`: outbound
- `mcp__agents__read_web_page`: untrusted-input, outbound
- `mcp__agents__extract_web_data`: untrusted-input, outbound

| HTTP status of an anonymous initialize | `200` |
| tools/list served without credentials | `yes` |

- **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 4 tools that change things (4 write). Whether a call also works without credentials was not tested: tools are never called.

https://mcp.vevang.com/mcp: tools/list returned 6 tools to an anonymous client, including make_marketing_video (write), check_ai_visibility (write), verify_output (write), extract_web_data (write)
