## Findings

No check matched anything in these tool definitions.


## Can't be undone (1)

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

### `set_refund_address`

- The name "set_refund_address" says "set": a word for a change.
- The name "set_refund_address" also says "refund": a word that usually means money moves, which cannot be taken back.

Description, as the server wrote it:

```untrusted-server-text
Only when get_swap shows customerState { kind: "action_required", action: "refund_address" }. Saves one immutable destination; it does not start a transfer by itself.
```

## Changes things (1)

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

### `create_swap`

- The name "create_swap" says "create": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Create a durable order that spends `amount` of fromToken. Returns the deposit address and exact amount to send. Confirm with the user first. Never retry after a timeout or error: another call creates another order.
```

## Only reads (4)

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

### `get_quote`

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

Description, as the server wrote it:

```untrusted-server-text
Estimate a swap. side "from" (default) quotes spending `amount`; side "to" quotes receiving `amount`. A quote is an estimate, not a funding instruction.
```

### `get_swap`

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

Description, as the server wrote it:

```untrusted-server-text
Current status and customerState of an order. Amounts are atomic; *Decimals fields give scale.
```

### `list_chains`

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

Description, as the server wrote it:

```untrusted-server-text
Chains available right now, which ids can be a source or a destination, and featured tokens.
```

### `search_tokens`

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

Description, as the server wrote it:

```untrusted-server-text
Find a token address and decimals by symbol, name or address.
```
