## Exfil surface

3 private-data -> untrusted-input -> outbound paths in this server alone. Denying 1 untrusted-input tool breaks every one: `mcp__falcon-docs__preview_document`.

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

| Private data | Untrusted input | Outbound |
| --- | --- | --- |
| `mcp__falcon-docs__preview_document` | `mcp__falcon-docs__preview_document` | `mcp__falcon-docs__extract_document` |

## Findings

No check matched anything in these tool definitions.


## Changes things (2)

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

### `extract_document`

- Nothing in its name or description says what it does, so it is counted as a write.
- Tag outbound: The input takes a URL (input.url): a request to a URL can carry data to whoever runs it.

Description, as the server wrote it:

```untrusted-server-text
Full extraction of all pages. Costs $0.03 USDC (x402).
```

### `spread_bank_statement`

- Nothing in its name or description says what it does, so it is counted as a write.
- Tag outbound: The input takes a URL (input.url): a request to a URL can carry data to whoever runs it.

Description, as the server wrote it:

```untrusted-server-text
Bank statement → every transaction + underwriting metrics (ADB, NSF, MCA/loan positions, revenue trend, DSCR inputs, tamper flags). Costs $0.25 USDC (x402).
```

## Only reads (1)

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

### `preview_document`

- The name "preview_document" says "preview": a word for reading.
- Tag private-data: The name "preview_document" says "preview" and "document": it reads documents. The input names a file (input.file_base64), and the tool reads: it reads files.
- Tag untrusted-input: 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:

```untrusted-server-text
Free: extract page 1 of a PDF (auto-detects invoice/receipt/PO/W-9/bank statement) with per-field confidence.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `falcon-docs`:

```json
{
  "permissions": {
    "allow": [],
    "ask": [
      "mcp__falcon-docs__preview_document",
      "mcp__falcon-docs__extract_document",
      "mcp__falcon-docs__spread_bank_statement"
    ],
    "deny": []
  }
}
```

Capability tags behind the rules (a read tagged outbound is asked about):

- `mcp__falcon-docs__preview_document`: private-data, untrusted-input, outbound
- `mcp__falcon-docs__extract_document`: outbound
- `mcp__falcon-docs__spread_bank_statement`: outbound
