## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data 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. | `mcp__crypto-quant__backtest` `mcp__crypto-quant__get_schema` `mcp__crypto-quant__health` `mcp__crypto-quant__market_signals` `mcp__crypto-quant__optimize_strategy` `mcp__crypto-quant__token_check` `mcp__crypto-quant__universe_snapshot` `mcp__crypto-quant__validate_backtest` `mcp__crypto-quant__validate_optimize` `mcp__crypto-quant__validate_token_check` `mcp__crypto-quant__validate_universe` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

No check matched anything in these tool definitions.


## Changes things (4)

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

### `backtest`

- 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.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Backtest any crypto strategy on 399 Coinbase coins, bias-free. Breakout, momentum, dip-buy or MA trend rules on Coinbase daily data with fees, slippage, H1/H2 split, luck flag and survivorship-bias-free universe. Price: $0.05 USDC per call (x402, Base mainnet). Free pre-check: validate_backtest.
```

### `health`

- 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.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Free: service status, prices, network and data range.
```

### `market_signals`

- 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.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Daily crypto market regime: BTC/ETH trend, breadth, breakout watchlist. BTC/ETH vs 20/50-day MAs, market breadth (% of point-in-time top-N above 20DMA), coins nearest a 20-day breakout, and the R1 breakout strategy's gate and entry signals. Completed UTC daily closes only. Price: $0.01 USDC per call (x402, Base mainnet).
```

### `token_check`

- 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.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Token scam check: honeypot, mint/pause/blacklist, fake-USDC lookalikes. Scam/honeypot/rug risk check for a Base, Ethereum or Solana token: unverified code, sell restrictions, mint/pause/blacklist powers, taxes, upgradeable proxy, age, liquidity, fake major-token impersonation and spam-airdrop patterns. Never visits metadata URLs. Price: $0.02 USDC per call (x402, Base mainnet). Free pre-check: validate_token_check.
```

## Only reads (7)

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

### `get_schema`

- The name "get_schema" says "get": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Free: request schemas, examples, prices and limits for every paid tool/endpoint.
```

### `optimize_strategy`

- The description's first verb is "find": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Find robust strategy params, not lucky ones: tests up to 50 combos of a backtest strategy; ranks by worst-half (H1/H2) return with neighbourhood smoothing, flags overfitting, and recommends the most robust parameters rather than the best-fit ones. Price: $0.50 USDC per call (x402, Base mainnet). Free pre-check: validate_optimize.
```

### `universe_snapshot`

- The name "universe_snapshot" says "snapshot": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Survivorship-free top-N coin list for any past date. Top-N Coinbase USD pairs by trailing 20-day dollar volume as of a past date, using only data available that day (survivorship-bias-free universe for backtests). Price: $0.05 USDC per call (x402, Base mainnet). Free pre-check: validate_universe.
```

### `validate_backtest`

- The name "validate_backtest" says "validate": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```

```

### `validate_token_check`

- The name "validate_token_check" says "validate": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

```untrusted-server-text
Free: format-check a token_check request (no on-chain lookups).
```

### `validate_universe`

- The name "validate_universe" says "validate": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```

## Claude Code permissions
