## 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.


## Changes things (1)

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

### `prepare_business_brief`

- 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:

```untrusted-server-text
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.
```

## Only reads (1)

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

### `find_businesses`

- The name "find_businesses" says "find": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
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.
```

## Claude Code permissions

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

  "permissions": {
    "allow": [
      "mcp__baron__find_businesses"
    ],
    "ask": [
      "mcp__baron__prepare_business_brief"
    ],
    "deny": []
  }
}

| Fact | Observed |

| HTTP status of an anonymous initialize | `200` |
| tools/list served without credentials | `yes` |
| Tools that change things, listed without credentials | `1` |

- **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 1 tool that changes things (1 write). Whether a call also works without credentials was not tested: tools are never called.

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