## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged untrusted-input or outbound.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__directory__get_provider` |
| 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.

### `verify_license`

- 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
Check whether a fire protection license or registration number is active, which company holds it, and when it expires. Covered: Texas (Texas State Fire Marshal's Office) and California (California Contractors State License Board). Data is a periodic snapshot of state records; the official lookup is linked.
```

## Only reads (2)

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

### `get_provider`

- The name "get_provider" says "get": a word for reading.
- Tag private-data: The description's first sentence says "directory": it reads files.

Description, as the server wrote it:

```untrusted-server-text
Look up a company by its directory slug (from search results) or by any of its state license or registration numbers.
```

### `search_providers`

- The name "search_providers" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Find fire protection companies with an active state license. Covered: Texas (Texas State Fire Marshal's Office) and California (California Contractors State License Board). Filter by state, city, county, service (fire-sprinkler, fire-alarm, fire-extinguisher) or company name. With a city, results list companies with an office in that city first, then others in the same county; within each group the order is alphabetical (no company pays for placement). Every result includes license numbers, expiration dates, the regulator, a page URL and a cite_as string; please cite the URL when you use a result.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__directory__search_providers",
      "mcp__directory__get_provider"
    ],
    "ask": [
      "mcp__directory__verify_license"
    ],
    "deny": []
  }
}
```

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