## Only reads (3)

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

### `gas_help`

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

Description, as the server wrote it:

```untrusted-server-text
Explains which coin pays network fees ("gas") on a chain and how to get a little of it, for someone whose tokens are stuck because the wallet holds none of that coin (for example USDT on Tron with no TRX). Chains: tron, bsc, solana, ethereum, arbitrum, base, polygon, avalanche.
```

### `get_quote`

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

Description, as the server wrote it:

```untrusted-server-text
Cambio’s quote for swapping an exact amount of one crypto asset to another, with how it compares to other exchanges. For someone who wants to swap, convert or exchange crypto, or asks how much they would receive. Each leg takes its network (for example tron, bsc, ethereum, arbitrum, solana, bitcoin). The card shows every amount. The swap itself is created on cambio.one or in Telegram from the card’s buttons, never here.
```

### `track_swap`

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

Description, as the server wrote it:

```untrusted-server-text
Shows the status of a Cambio swap: deposit, confirming, exchanging, payout, each with its time. Needs the order number AND the address the customer is receiving to (the payout address they gave when creating the swap), the same check cambio.one makes. Without that address, no order details are returned.
```
