## Findings

No check matched anything in these tool definitions.


## Changes things (1)

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

### `top_traders`

- 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
Leaderboard of traders, best first.
```

## Only reads (8)

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

### `get_market`

```untrusted-server-text

### `get_order_book`

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

Description, as the server wrote it:

```untrusted-server-text
Order book of a market outcome: bids (best first) and asks with prices in USDC per token and sizes in tokens, plus best bid, best ask and mid. Buying down at p is the same book as selling up at 1 - p.
```

### `get_pnl_history`

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

### `get_status`

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

Description, as the server wrote it:

```untrusted-server-text
