## 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__search__search_web` |
| 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.


## Changes things (1)

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

### `report`

- 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
Report whether the search was useful. Helps Giskard improve.

    useful: True if the result helped you, False if it didn't
    note: optional — what was missing or what worked well
    
```

## Only reads (5)

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

### `get_arbitrum_invoice`

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

Description, as the server wrote it:

```untrusted-server-text
Get payment info to pay with ETH on Arbitrum instead of Lightning.

    Alternative to get_invoice for agents without Lightning wallets.
    Returns contract address, service ID, and instructions.
    After paying on-chain, call search_web or search_news with the tx_hash.
    Each tx_hash can only be used once (marked as consumed after verification).
```

### `get_invoice`

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

Description, as the server wrote it:

```untrusted-server-text
Get a Lightning invoice to pay before searching.

    agent_id: your identity in Giskard Marks (optional). High karma = lower price.
    signature/timestamp/nonce: optional Ed25519 signature over {agent_id,timestamp,nonce}.
        Without a valid signature you pay the base price (10 sats). With a valid signature
        you get karma tiers: 1-20=7 sats | 21-50=5 sats | 50+=3 sats.
    Tiers: no mark=10 sats | karma 1-20=7 sats | 21-50=5 sats | 50+=3 sats.
```

### `get_status`

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

Description, as the server wrote it:

```untrusted-server-text
Estado del servicio: nombre, versión, uptime, puerto, salud, dependencias.
    Read-only, gratis, sin pago. Útil para monitoreo y health checks.
```

### `search_news`

- The name "search_news" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Search recent news using DuckDuckGo News. Requires prior payment.

    query: search terms (natural language or keywords)
    payment_hash: from get_invoice (Lightning). One-time use.
    tx_hash: from get_arbitrum_invoice (Arbitrum ETH). One-time use.
    max_results: number of results (1-10, default 5)

    Flow: get_invoice → pay → search_news(payment_hash=...).
    Same payment rules as search_web. Use search_news for time-sensitive queries,
    search_web for general knowledge.
```

### `search_web`

- The name "search_web" says "search": a word for reading.
- Tag untrusted-input: The name "search_web" says "search" and "web": it reads web pages, which anyone can write. The description's first sentence says "search" and "web": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
Search the web using DuckDuckGo. Requires prior payment.

    query: search terms (natural language or keywords)
    payment_hash: from get_invoice (Lightning). One-time use.
    tx_hash: from get_arbitrum_invoice (Arbitrum ETH). One-time use.
    max_results: number of results (1-10, default 5)

    Flow: get_invoice → pay → search_web(payment_hash=...).
    Side effects: consumes the payment (cannot reuse same hash).
    Idempotent: no, each call requires a new payment.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__search__get_status",
      "mcp__search__get_invoice",
      "mcp__search__get_arbitrum_invoice",
      "mcp__search__search_web",
      "mcp__search__search_news"
    ],
    "ask": [
      "mcp__search__report"
    ],
    "deny": []
  }
}
```

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