## 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.

### `swap_build_tx`

- The input addresses people (input.recipient): what it sends cannot be taken back.

Description, as the server wrote it:

```untrusted-server-text
Build an unsigned, non-custodial swap transaction (plus ERC-20 approval tx if needed) for the caller's wallet to sign. Same fee as swap_quote.
```

## Changes things (3)

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

### `crosschain_create_shift`

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

Description, as the server wrote it:

```untrusted-server-text
Create a variable-rate SideShift order; returns a deposit address. Funds settle directly to settleAddress (non-custodial for us).
```

### `crosschain_rate`

- 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
Cross-chain / cross-asset rate (BTC, XMR, LTC, SOL, ETH, USDC on many networks) via SideShift.ai. Same rate as sideshift.ai.
```

### `swap_quote`

- 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
Best-price same-chain token swap quote via the KyberSwap aggregator (ethereum, base, arbitrum, optimism, polygon, bsc). Includes a disclosed 0.1% integrator fee.
```

## Only reads (1)

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

### `shift_status`

- The name "shift_status" says "status": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Status of a SideShift order created here.
```
