## Exfil surface

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

| 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__swap__swap_quote` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__swap__swap_quote` |

## Findings

- **warn** Annotations that disagree with the tool in `swap_quote` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "swap_quote" read-only (readOnlyHint: true), and its own name, description or input give the class "irreversible".

annotations: {"readOnlyHint":true,"openWorldHint":true}; The input addresses people (input.recipient): what it sends cannot be taken back.
```


## Can't be undone (1)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `swap_quote`

- The input addresses people (input.recipient): what it sends cannot be taken back.
- 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.
- Tag outbound: The input takes a destination (input.recipient): what the tool writes goes there.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Best-price token swap on one EVM chain (KyberSwap aggregator) or cross-chain bridge (LI.FI, fallback Relay; set toChain). Returns expected and minimum output, price impact, gas, every fee (MoneyTools fee: 0.25% on same-chain swaps, disclosed), safety warnings, and an UNSIGNED transaction (plus exact-amount ERC-20 approval) for your own wallet to sign. Free. Never signs or holds funds.
```

## Only reads (1)

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

### `list_swap_tokens`

- The name "list_swap_tokens" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List supported chains, chain ids, native tokens and the token symbols accepted by swap_quote (any ERC-20 address also works with amountBaseUnits).
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__swap__list_swap_tokens"
    ],
    "ask": [
      "mcp__swap__swap_quote"
    ],
    "deny": []
  }
}
```

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

- `mcp__swap__swap_quote`: untrusted-input, outbound
