## Exfil surface

1 private-data -> untrusted-input -> outbound path in this server alone. Denying 1 outbound tool breaks every one: `mcp__business-lookup__business_lookup`.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__business-lookup__business_lookup` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__business-lookup__business_lookup` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__business-lookup__business_lookup` |

| Private data | Untrusted input | Outbound |
| --- | --- | --- |
| `mcp__business-lookup__business_lookup` | `mcp__business-lookup__business_lookup` | `mcp__business-lookup__business_lookup` |

## Findings

No check matched anything in these tool definitions.


## Only reads (1)

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

### `business_lookup`

- The name "business_lookup" says "lookup": a word for reading.
- Tag private-data: The description's first sentence says "read" and "contact": it reads contacts.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. The description's first sentence says "read" and "http": it reads web pages, which anyone can write. The input takes a URL (input.url), and the tool reads it: it reads web pages, which anyone can write.
- Tag outbound: The input takes a URL (input.url): a request to a URL can carry data to whoever runs it.
- Claude Code: ask, because it is tagged outbound.

Description, as the server wrote it:

As is; not advice or verification. $0.005 USDC x402. Max 3 requests. Provided as is, with no warranty or guarantee of accuracy or fitness.
