**3 tools: 1 do something that can't be undone and 2 change things.**

| Group | Class | Tools | Claude Code |
| --- | --- | --- | --- |
| Deletes or cancels | destructive | 0 | deny |
| Can't be undone | irreversible | 1 | ask |
| Changes things | write | 2 | ask |
| Only reads | read | 0 | allow |

## 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.


## Can't be undone (1)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `simulate_transfer`

- The name "simulate_transfer" says "transfer": a word for a change that another call does not undo.

Description, as the server wrote it:

```untrusted-server-text
Simulate buy-then-sell on-chain. Args: address (0x...), chain. Returns: canBuy, canSell, revertReason, verdict (ALLOW/REVIEW/BLOCK). Uses real eth_call simulation.
```

## Changes things (2)

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

### `honeypot_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
Fast honeypot check. Args: address (0x...), chain. Returns: honeypot boolean, canBuy, canSell, buyTax, sellTax, riskScore.
```

### `scan_token`

- 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
Full token security scan. Args: address (0x...), chain (ethereum|base|arbitrum|optimism|polygon|bsc|avalanche). Returns risk score 0-100, honeypot, tax, source verification.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `token-security`:

```json
{
  "permissions": {
    "allow": [],
    "ask": [
      "mcp__token-security__scan_token",
      "mcp__token-security__honeypot_check",
      "mcp__token-security__simulate_transfer"
    ],
    "deny": []
  }
}
```

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T15:16:23.369Z, unchanged since 2026-10-22T15:16:23.369Z. No credentials were sent and no tool was called. Values are shown as the endpoint returned them. Method: https://anlyon.dev/methodology#remote-posture

| Fact | Observed |
| --- | --- |
| Reachable | `yes` |
| HTTP status of an anonymous initialize | `200` |
| tools/list served without credentials | `yes` |
| Tools that change things, listed without credentials | `3` |
| Protocol version | `2025-03-26` |
| WWW-Authenticate on 401 | `not observed` |
| resource_metadata in WWW-Authenticate | `none` |
| RFC 9728 protected resource metadata | `none` |
| Authorization servers | `none` |
| Legacy HTTP+SSE transport | `no` |
| Dynamic client registration | `not observed` |
| Client ID metadata documents | `not observed` |

- **high** 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 (1 irreversible, 2 write). Whether a call also works without credentials was not tested: tools are never called.

https://hexscan.xyz/mcp: tools/list returned 3 tools to an anonymous client, including simulate_transfer (irreversible), scan_token (write), honeypot_check (write)
```
