## Findings

No check matched anything in these tool definitions.


## Changes things (3)

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

### `build_swap_tx`

- 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
Free. Returns an UNSIGNED base64 transaction for the taker wallet to sign. Advan never signs and never holds keys. Default (selfBroadcast false) keeps JupiterZ routes, which need Jupiter POST /swap/v2/execute to add the market-maker co-signature. Pass selfBroadcast true to exclude jupiterz so the taker can broadcast the signed transaction.
```

### `token_risk`

- 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
Paid token risk report ($0.02 USDC via x402 exact on solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp). Combines RPC mint/freeze authority, Jupiter Tokens V2, and RugCheck. Ordinary MCP clients that cannot pay receive a payment-required error.
```

### `wallet_portfolio`

- 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
Paid wallet portfolio ($0.02 USDC via x402 exact). SOL plus SPL Token and Token-2022 balances, priced with Jupiter Price V3.
```

## Only reads (1)

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

### `get_quote`

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

Description, as the server wrote it:

```untrusted-server-text
Free Jupiter Swap API V2 quote (GET /swap/v2/order, no taker). Returns amounts, route, slippage, and referral fee fields. Does not return a transaction.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__advan__get_quote"
    ],
    "ask": [
      "mcp__advan__build_swap_tx",
      "mcp__advan__token_risk",
      "mcp__advan__wallet_portfolio"
    ],
    "deny": []
  }
}
```
