## 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__x402-scraper-api__scrape_markdown` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__x402-scraper-api__check_url` `mcp__x402-scraper-api__extract_structured` `mcp__x402-scraper-api__page_changed` `mcp__x402-scraper-api__scrape_markdown` |

## 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_url`

- 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
FREE: preflight target URL safety and pricing
```

### `extract_structured`

- 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
PAID $0.02 USDC (x402, Base): URL plus JSON schema to structured JSON. Over MCP this returns payment requirements; settle by calling POST /v1/extract with x402 payment headers.
```

### `page_changed`

- 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
PAID $0.003 USDC (x402, Base): Whether a page changed since a hash or timestamp. Over MCP this returns payment requirements; settle by calling POST /v1/page/changed with x402 payment headers.
```

### `scrape_markdown`

- Nothing in its name or description says what it does, so it is counted as a write.
- Tag untrusted-input: The name "scrape_markdown" 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
PAID $0.005 USDC (x402, Base): URL to clean markdown. Over MCP this returns payment requirements; settle by calling POST /v1/scrape/markdown with x402 payment headers.
```

## Only reads (1)

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

### `compare_market_rules`

- The name "compare_market_rules" says "compare": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
PAID $0.05 USDC (x402, Base): Compare Polymarket rules with a bookmaker market description. Over MCP this returns payment requirements; settle by calling POST /v1/market-rules/compare with x402 payment headers.
```
