## Findings

No check matched anything in these tool definitions.


## Changes things (4)

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

### `address_report`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
One-call snapshot of any Base address: ETH balance, USDC balance, transaction count, and whether it is a smart contract or a regular wallet. Use it to sanity-check a counterparty or a payment address before sending funds. Input: a 0x address.
```

### `gas_now`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Current gas price on the Base network (Coinbase's Ethereum L2), in gwei and wei, read live from a Base RPC node. Use before sending a Base transaction or estimating its cost. Takes no input.
```

### `token_balance`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
How much of an ERC-20 token a wallet holds on Base, returned both human-formatted (using the token's decimals) and raw. Pass the token contract address and the holder address, both 0x + 40 hex. Example: USDC 0x833589fcd6edb6e08f4c7c32d4f71b54bda02913.
```

### `token_info`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
ERC-20 token metadata on Base, read on-chain: name, symbol, decimals, and total supply, plus whether the address really behaves like an ERC-20. Use it to verify a token contract before trusting or displaying it. Input: the token contract address (0x + 40 hex).
```

## Only reads (1)

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

### `tx_status`

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

Description, as the server wrote it:

```untrusted-server-text
Look up a Base transaction by hash and report whether it is pending, succeeded, or failed, with from, to, value, block number, and gas used. Use it to confirm a payment or contract call landed. Input: the transaction hash (0x + 64 hex; the 0x is optional).
```
