## 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__crypto-pulse__get_market_pulse` `mcp__crypto-pulse__get_market_sample` `mcp__crypto-pulse__get_market_spots` |
| 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.


## Only reads (3)

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

### `get_market_pulse`

- The name "get_market_pulse" says "get": a word for reading.
- 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
PAID live full pulse ($0.02 USDC on Solana via x402). One call replaces four data sources (spots + Fear & Greed + Hyperliquid funding + DefiLlama). This MCP tool returns payment requirements and the HTTP URL — pay via x402 HTTP (Solana USDC), then GET the URL. For a free preview call get_market_sample first.
```

### `get_market_sample`

- The name "get_market_sample" says "get": a word for reading.
- 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
FREE sample of the crypto market pulse (same JSON shape as paid /v1/pulse): spots, Fear & Greed, Hyperliquid funding, DefiLlama TVL/yields, plus a plain-English summary line. Data may be up to 15 minutes old. Use get_market_pulse for live paid data.
```

### `get_market_spots`

- The name "get_market_spots" says "get": a word for reading.
- 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
PAID live BTC/ETH/SOL/HYPE spot prices only ($0.005 USDC). Returns payment requirements + HTTP URL for x402. Prefer get_market_pulse when you also need Fear & Greed, funding, or DeFi. Free preview: get_market_sample.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `crypto-pulse`:

```json
{
  "permissions": {
    "allow": [
      "mcp__crypto-pulse__get_market_sample",
      "mcp__crypto-pulse__get_market_pulse",
      "mcp__crypto-pulse__get_market_spots"
    ],
    "ask": [],
    "deny": []
  }
}
```

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

- `mcp__crypto-pulse__get_market_sample`: untrusted-input
- `mcp__crypto-pulse__get_market_pulse`: untrusted-input
- `mcp__crypto-pulse__get_market_spots`: untrusted-input
