| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__signals__find_vaults` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | none |

## Findings

No check matched anything in these tool definitions.


## Only reads (4)

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

### `analyze_wallet`

- The name "analyze_wallet" says "analyze": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Look up a specific wallet's worth-copying read (copyability / Realizability Score / risk) by address. venue 'hl' (Hyperliquid) or 'pm' (Polymarket).
```

### `find_copyable_traders`

- The name "find_copyable_traders" says "find": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List Hyperliquid traders that are actually copyable AND realizable for a follower, pre-gated by copy-lag decay, de-leverage, and alpha-vs-beta (NOT raw leaderboard PnL). Returns copyability tier, Realizability Score 0-100, risk grade, PnL, return, copy-lag tolerance. Use when you need vetted copy candidates, not noisy 'top trader' lists.
```

### `find_pm_traders`

- The name "find_pm_traders" says "find": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List Polymarket wallets with copyability classification (edge-family), PnL, edge-per-dollar, drawdown, category, invisible-maker volume. PM is structurally near-uncopyable; useful for edge-family research.
```

### `find_vaults`

- The name "find_vaults" says "find": a word for reading.
- Tag private-data: The name "find_vaults" says "find" and "vault": it reads secrets. The description's first sentence says "list" and "vault": it reads secrets.

Description, as the server wrote it:

```untrusted-server-text
List Hyperliquid vaults ranked by allocation-worthiness (Sharpe, drawdown, operator skin-in-game, concentration, fees). Vaults are deposit products. Returns verdict, risk score, CAGR, max drawdown, TVL, APR.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `signals`:

```json
{
  "permissions": {
    "allow": [
      "mcp__signals__find_copyable_traders",
      "mcp__signals__find_vaults",
      "mcp__signals__find_pm_traders",
      "mcp__signals__analyze_wallet"
    ],
    "ask": [],
    "deny": []
  }
}
```

Capability tags behind the rules (a read tagged outbound is asked about):

- `mcp__signals__find_vaults`: private-data
