**4 tools: 3 change things and 1 only read.**

| Group | Class | Tools | Claude Code |
| --- | --- | --- | --- |
| Deletes or cancels | destructive | 0 | deny |
| Can't be undone | irreversible | 0 | ask |
| Changes things | write | 3 | ask |
| Only reads | read | 1 | allow |

## 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__pnllabs__check_token_safety` `mcp__pnllabs__check_trade_cost` `mcp__pnllabs__check_wallet_forensics` `mcp__pnllabs__check_wallet_trust` |
| 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 (3)

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

### `check_trade_cost`

- 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
Estimates what a trade of a given size would cost in a Solana token's main liquidity pool. Returns: expected slippage in percent, an estimated round-trip cost calibrated against measured live execution overhead, a recommended maximum size in SOL, pool liquidity, and a verdict (ACCEPTABLE_COST, ELEVATED_COST, HIGH_COST, UNTRADEABLE, NO_POOL, UNKNOWN).
```

### `check_wallet_forensics`

- 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
Traces where a Solana wallet's funding came from and how old it is, using on-chain transfer history. Returns: origin classification (CEX_FUNDED, WALLET_FUNDED, UNKNOWN_ORIGIN, UNVERIFIABLE_ORIGIN, UNKNOWN), the funding transaction, wallet age, and a fresh_wallet flag.
```

### `check_wallet_trust`

- 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
Recomputes the realized SOL profit and loss of a Solana wallet from its on-chain transaction history and returns a trust verdict. Returns: verdict (TRUSTED, NEUTRAL, UNTRUSTED, INSUFFICIENT, UNVERIFIABLE, UNKNOWN), a confidence level, realized profit/loss in SOL, the number of coins analyzed, stable reason codes, and flags such as known_sniper_bot. Returns UNVERIFIABLE when the history cannot be reconstructed reliably rather than estimating.
```

## Only reads (1)

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

### `check_token_safety`

- The description's first verb is "analyze": 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
Analyzes structural risk of a Solana token from on-chain data: real-holder concentration with bonding-curve and liquidity-pool accounts excluded, presence of known sniper-bot addresses among early buyers, and a simulated buy/sell round trip to detect honeypot behavior. Returns: verdict (LOW_RISK, ELEVATED, HIGH_RISK, CRITICAL, UNKNOWN), stable reason codes, and top-holder percentages. Scope is structural only; it does not detect risk that exists purely in trading behavior.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__pnllabs__check_token_safety"
    ],
    "ask": [
      "mcp__pnllabs__check_wallet_trust",
      "mcp__pnllabs__check_wallet_forensics",
      "mcp__pnllabs__check_trade_cost"
    ],
    "deny": []
  }
}
```

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

- `mcp__pnllabs__check_wallet_trust`: untrusted-input
- `mcp__pnllabs__check_wallet_forensics`: untrusted-input
- `mcp__pnllabs__check_trade_cost`: untrusted-input
- `mcp__pnllabs__check_token_safety`: untrusted-input

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T14:54:07.265Z, unchanged since 2026-10-22T14:54:07.265Z. No credentials were sent and no tool was called. Values are shown as the endpoint returned them. Method: https://anlyon.dev/methodology#remote-posture

| HTTP status of an anonymous initialize | `200` |
| tools/list served without credentials | `yes` |
| Tools that change things, listed without credentials | `3` |

- **warn** Tools that change things, listed to anyone ([unauth-remote-writes](https://anlyon.dev/methodology#unauth-remote-writes))

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 3 tools that change things (3 write). Whether a call also works without credentials was not tested: tools are never called.

https://api.pnllabs.com/mcp: tools/list returned 4 tools to an anonymous client, including check_wallet_trust (write), check_wallet_forensics (write), check_trade_cost (write)
