## 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__sentiment__get_events` `mcp__sentiment__get_sentiment` `mcp__sentiment__get_sentiment_history` |
| 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 (4)

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

### `get_events`

- The name "get_events" 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
Recent classified market events for a symbol. Kill-switch trio: hack_exploit, regulation, delisting — the reference integrations stand aside for 24h after one. Report the event headline and source link, not just a risk flag.
```

### `get_sentiment`

- The name "get_sentiment" 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
Latest news-sentiment signal per symbol (batch up to 50 in one call — one signal per asset per hour, so never poll faster than hourly). On the free plan, symbols outside BTC-USD/ETH-USD/SOL-USD are 24h delayed: check `timestamp` and disclose staleness.
```

### `get_sentiment_history`

- The name "get_sentiment_history" 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
Point-in-time sentiment series for backtesting: `bucket` is the as-of time, no lookahead. `from`/`to` are clamped to your plan's history window and to its per-request span, then echoed back — check them rather than assuming. `reconstructed: true` buckets were rebuilt from archival news, not live-collected; disclose the mix in any backtest.
```

### `get_symbols`

- The name "get_symbols" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
The supported symbol universe with each symbol's free-plan freshness. Static — costs no quota and needs no API key.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__sentiment__get_sentiment",
      "mcp__sentiment__get_sentiment_history",
      "mcp__sentiment__get_events",
      "mcp__sentiment__get_symbols"
    ],
    "ask": [],
    "deny": []
  }
}
```

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

- `mcp__sentiment__get_sentiment`: untrusted-input
- `mcp__sentiment__get_sentiment_history`: untrusted-input
- `mcp__sentiment__get_events`: untrusted-input
