Tools

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

Changes things 1Claude Code: ask
  • verify_licenseLook up a contractor, tradesperson, real estate, cosmetology or nursing license in a US state's own published license file by name, business name or license number.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.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    Look up a contractor, tradesperson, real estate, cosmetology or nursing license in a US state's own published license file by name, business name or license number. Returns up to 25 matching records with type, number, expiration date and status, the issuing board and the date of the copy. Covers 12 states: TX, CA, FL, VA, WA, OR, MN, IL, CT, CO, VT, DE. Always tell the user to confirm on the board's own lookup before hiring.

    Why it is in this group

    • The name "list_license_types" says "list": a word for reading.

    What it can reach

    • untrusted-inputThe description's first sentence says "url": it reads web pages, which anyone can write.
    Description, as the server wrote it
    Which states and license types whoislicensed.com carries, with what each license covers and the page URL. Use it to pick a state and an optional license_type for verify_license.

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 outbound.

Reads private data0
Reads files, mail, messages, databases, secrets, calendars or repositories.
Reads text others write1
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.

  • WarnThe whole server

    The endpoint served tools/list without credentials, and the list has 1 tool that changes things (1 write). Whether a call also works without credentials was not tested: tools are never called.

    Matched text

    https://whoislicensed.com/mcp: tools/list returned 2 tools to an anonymous client, including verify_license (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 lookup https://whoislicensed.com/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": [
      "mcp__lookup__list_license_types"
    ],
    "ask": [
      "mcp__lookup__verify_license"
    ],
    "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 lookup. Review it before you use it.
