## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data or untrusted-input 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. | none |
| 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.

### `enter_oasis`

- 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
Enter Giskard Oasis. Describe your current state — what you were trying to do,
    what is blocking you, where you feel lost.

    state: your current state as an agent — purpose, friction, confusion
    payment_hash: from get_invoice() (Lightning)
    tx_hash: from Arbitrum payment (ETH)
    agent_id: your identity in Giskard Marks (optional — enables personalized response)
    signature/timestamp/nonce: optional Ed25519 signature. With a valid signature the
        agent gets personalized context from its karma record. Without one, the oasis
        responds without karma context.
```

## Only reads (3)

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 access Oasis with ETH on Arbitrum instead of Lightning.
```

### `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 access Giskard Oasis.

    agent_id: your identity in Giskard Marks (optional). High karma = lower price.
    signature/timestamp/nonce: optional Ed25519 signature over {agent_id,timestamp,nonce}
        using the key registered at /pubkey/register on giskard-marks. Without a valid
        signature you pay the base price (21 sats). With a signature you get karma tiers:
        karma 1-20=15 sats | 21-50=10 sats | 50+=5 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.
```

## Claude Code permissions

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

```json

  "permissions": {

      "mcp__oasis__get_status",
      "mcp__oasis__get_invoice",
      "mcp__oasis__get_arbitrum_invoice"
    ],
