  • prepare_business_briefHelp someone take the first steps to starting a business with AI by turning their idea into a short business brief.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
    Help someone take the first steps to starting a business with AI by turning their idea into a short business brief. Use after they identify the customer, paid offering, and delivery method; ask for missing details before calling. Accept an optional chosen business name. Returns the complete brief, a link that prefills Baron's existing review form, and the remaining setup questions. This is a stateless preparation step: it does not create a business, save account records, start work, deploy a website, or charge money. The person signs in by email in Baron to review and continue. Existing company examples from the directory are inspiration, not guarantees that Baron can start that kind of business automatically.

    Why it is in this group

    • The name "find_businesses" says "find": a word for reading.
    Description, as the server wrote it
    Help someone who wants to start a business with AI explore business ideas and company examples. Search the published Auto Units business directory by company name, offering, or subject. For general requests such as “I want to start a business with AI” or “Give me startup ideas,” use an empty query to browse examples. Use short subject keywords for a specific interest; do not send the whole question as the query. Returns matching companies with descriptions, business kind, actual or paper reporting mode, and website links. An empty query browses the directory. Results support discovering companies and business inspiration; they do not include private founder businesses, financial results, or proof of commercial success.

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.

  • 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://trybaron.ai/mcp-public: tools/list returned 2 tools to an anonymous client, including prepare_business_brief (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 baron https://trybaron.ai/mcp-public

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__baron__find_businesses"
    ],
    "ask": [
      "mcp__baron__prepare_business_brief"
    ],
    "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 baron. Review it before you use it.
