## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged outbound.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__privi-verify__privi_lookup_fingerprint` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__privi-verify__privi_token_market` |
| 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 (4)

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

### `privi_chain_of_custody`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Full ordered event history for a lot with each event's fingerprint, plus an
integrity check of the whole chain. Paid per call via x402.
```

### `privi_record_event`

- 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
Append an event to a lot's history (manufacturers only). Requires
'Authorization: Bearer <key>' with a key from PRIVI_WRITE_KEYS. Over stdio,
writes are allowed only when PRIVI_ALLOW_LOCAL_WRITES=1.
```

### `privi_token_market`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- 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
PRIVI on Base: price, how much PRIVI and USDC the Privi swap desk holds (so whether a swap can fill),
any Uniswap v3 / Aerodrome pools, and optionally a swap quote. Every paid Privi tool also accepts PRIVI. Free.
```

### `privi_verify_lot`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Verify a lot: product, first and latest custody events, recall status, and whether
its record history is intact. Paid per call via x402.
```

## Only reads (2)

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

### `privi_lookup_fingerprint`

- The name "privi_lookup_fingerprint" says "lookup": a word for reading.
- Tag private-data: The description's first sentence says "document": it reads documents.

Description, as the server wrote it:

```untrusted-server-text
Check whether a record fingerprint (from a label, certificate or document) exists in Privi. Free.
```

### `privi_pricing`

- The description's first verb is "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List Privi Verify tools, what each costs, and how payment works.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__privi-verify__privi_pricing",
      "mcp__privi-verify__privi_lookup_fingerprint"
    ],
    "ask": [
      "mcp__privi-verify__privi_token_market",
      "mcp__privi-verify__privi_verify_lot",
      "mcp__privi-verify__privi_chain_of_custody",
      "mcp__privi-verify__privi_record_event"
    ],
    "deny": []
  }
}
```

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

- `mcp__privi-verify__privi_token_market`: untrusted-input
- `mcp__privi-verify__privi_lookup_fingerprint`: private-data
