No check matched anything in the tool definitions. No finding is not a safety guarantee. How the checks work.

Tools

Open a tool for its reasons and full description. Descriptions are the publisher's own words, shown as they are.

3 tools

Can't be undone 1Claude Code: ask
  • simulate_transferSimulate buy-then-sell on-chain.No findings

    Why it is in this group

    • The name "simulate_transfer" says "transfer": a word for a change that another call does not undo.
    Description, as the server wrote it
    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 2Claude Code: ask
  • honeypot_checkFast honeypot check.No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    Description, as the server wrote it
    Fast honeypot check. Args: address (0x...), chain. Returns: honeypot boolean, canBuy, canSell, buyTax, sellTax, riskScore.
  • scan_tokenFull token security scan.No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    Description, as the server wrote it
    Full token security scan. Args: address (0x...), chain (ethereum|base|arbitrum|optimism|polygon|bsc|avalanche). Returns risk score 0-100, honeypot, tax, source verification.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.

Exfil surface

Which tools read private data, which read text someone else can write, and which can send data out. One of each is a path a prompt injection can use.

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

Reads private data0
Reads files, mail, messages, databases, secrets, calendars or repositories.
Reads text others write0
Brings in text someone else can write: web pages, inbound email, messages, issues and comments.
Can send data out0
Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL.

Other servers in the same agent add their own tools to these paths. Audit your whole setup to see them together.

Remote posture

What anyone on the internet sees at the remote endpoint: an anonymous initialize and tools/list, and the public OAuth metadata.

  • HighThe whole server

    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.

    Matched text

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

    What this check looks for

Install

Pinned to version 1.0.0. Values in angle brackets are yours to fill in.

claude mcp add --transport http token-security https://hexscan.xyz/mcp

Run in a terminal.

Claude Code permissions

Allow the reads, ask before a change or a way out, deny the deletes. Paste into .claude/settings.json.

.claude/settings.json
{
  "permissions": {
    "allow": [],
    "ask": [
      "mcp__token-security__scan_token",
      "mcp__token-security__honeypot_check",
      "mcp__token-security__simulate_transfer"
    ],
    "deny": []
  }
}

Tools that only read are allowed, tools that change things ask first, tools that delete or cancel are denied. A read that can send data out (it takes a URL, say) asks first too. It assumes the server is installed as token-security. Review it before you use it.
