## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data or untrusted-input or outbound.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | none |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | none |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

No check matched anything in these tool definitions.


## Changes things (8)

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

### `bundle_check`

- 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
Bundle/sniper signals for a token (base, bsc, robinhood, arc): who bought
in the first blocks after launch, how much of the early supply they took,
and whether any were funded by the deployer or a shared wallet. Signals,
not advice. $0.02 USDC. Data by GeckoTerminal.
```

### `contract_check`

- 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
On-chain contract check (EVM chains: base, ethereum, arbitrum, optimism,
polygon, bsc): ownership renounced?, LP burn share, ERC-20 metadata, red
flags. $0.01 USDC.
```

### `deployer_history`

- 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
Deployer launch history from CurveCall's hourly launch-outcome index on
Base, Robinhood Chain and Arc (built since 2026-09-24): every launch this
deployer made and how it ended (survived, rugged, died), with rug rate and
dev-behavior flags (dev moved tokens, relaunch count). Answers 'has this
deployer rugged before?' $0.01 USDC. Data by GeckoTerminal.
```

### `precheck`

- 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
Pre-trade bundle: snapshot + risk screen + curve trade simulation in ONE
call. Tells you what your buy will do - quote, slippage, rug-risk verdict.
$0.01 USDC. No other x402 service sells trade simulation.
```

### `quote_buy`

- 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
Bonding-curve BUY quote (constant product, virtual reserves). $0.001 USDC.
```

### `quote_sell`

- 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
Bonding-curve SELL quote (constant product, virtual reserves). $0.001 USDC.
```

### `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
Heuristic 0-100 token risk screen with explainable flags. $0.01 USDC.
```

### `verdict`

- The description's first verb is "start": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
START HERE before buying a token. One call returns a buy / watch / avoid
decision with the reasons, risk score, key numbers (price, liquidity, volume,
age) and heuristic sizing and stop distance. $0.01 USDC. For full raw data
use precheck. Heuristic screen, not financial advice.
```

## Only reads (3)

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

### `search_tokens`

- The name "search_tokens" says "search": a word for reading.

Description, as the server wrote it:

Search tokens by name, symbol or contract address across chains.
$0.005 USDC.
```

### `token_snapshot`

- The name "token_snapshot" says "snapshot": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Normalized token market snapshot (price, liquidity, FDV, volume, age). $0.005 USDC.
```

### `wallet_snapshot`

- The name "wallet_snapshot" says "snapshot": a word for reading.
