## 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__scanpay__scrape_url` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__scanpay__scrape_url` |

## Findings

## Changes things (6)

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

### `audit_token`

- Nothing in its name or description says what it does, so it is counted as a write.
- Findings: warn base64-blob

Description, as the server wrote it:

```untrusted-server-text
Live on-chain token & smart contract rug-pull / honeypot shield for Base, Ethereum, and Solana. Inspects live EVM bytecode (blacklist selectors, mutable tax fees, pause toggles, unverified proxies) and Solana SPL / Token-2022 mint accounts (active mint authority, freeze authority, Permanent Delegate wallet seizure, Transfer Hook honeypots) plus live DexScreener liquidity and 24h buy/sell ratios. Price: $0.05 Base USDC or 0.00035 SOL.
```

### `create_session_deposit`

- The name "create_session_deposit" says "create": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Activate a prepaid session voucher (0.006 SOL or 0.85 Base USDC for 10 operations). Eliminates per-request payment prompts and RPC latency in autonomous agent loops.
```

### `health_check`

- 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
Check ScanPay engine health, available AST rules, and x402 payment configurations.
```

### `scan_code`

- Nothing in its name or description says what it does, so it is counted as a write.
- Findings: warn base64-blob

Description, as the server wrote it:

```untrusted-server-text
Deterministic code security scanner for AI agents. Analyzes Python, JavaScript, and TypeScript code for 45+ vulnerability patterns (injection, hardcoded secrets, wallet key exfiltration, SSRF, infinite x402 loops, unsimulated Solana transactions). Returns deterministic AST patches, unified diffs, and execution verdicts (PASS, WARN, BLOCK). Price: $0.10 Base USDC or 0.0007 SOL.
```

### `scrape_url`

- Nothing in its name or description says what it does, so it is counted as a write.
- Tag untrusted-input: The name "scrape_url" 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.
- Findings: warn base64-blob

Description, as the server wrote it:

```untrusted-server-text
Anti-bot web access & scraper oracle for AI agents. Fetches web pages with stealth headers to bypass Cloudflare Turnstile, WAFs, and anti-bot challenges. Purifies HTML by removing scripts, stylesheets, tracking pixels, ads, and navigation boilerplate, returning clean, token-efficient Markdown ready for LLM consumption with cryptographic oracle attestation. Price: $0.02 Base USDC or 0.00015 SOL.
```

### `simulate_tx`

- Nothing in its name or description says what it does, so it is counted as a write.
- Findings: warn base64-blob

Description, as the server wrote it:

```untrusted-server-text
Pre-flight transaction & drainer shield for AI agents. Simulates and inspects EVM (Base/Ethereum) and Solana transactions before signing or broadcasting. Detects unlimited approvals, known drainers, honeypots, MEV sandwich exposure (min_output=0), and unauthorized Solana authority takeovers. Returns execution verdict (ALLOW, WARN, BLOCK) and cryptographic oracle attestation. Price: $0.05 Base USDC or 0.00035 SOL.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [],
    "ask": [
      "mcp__scanpay__scan_code",
      "mcp__scanpay__simulate_tx",
      "mcp__scanpay__audit_token",
      "mcp__scanpay__scrape_url",
      "mcp__scanpay__create_session_deposit",
      "mcp__scanpay__health_check"
    ],
    "deny": []
  }
}
```

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

- `mcp__scanpay__scrape_url`: untrusted-input, outbound
