## Exfil surface

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

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

| Private data | Untrusted input | Outbound |

| `mcp__plumber__get_contact_info` | `mcp__plumber__get_contact_info` | `mcp__plumber__request_contact` |

## Findings

No check matched anything in these tool definitions.


## Changes things (2)

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

### `check_coverage`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Check whether Delco Plumber Now (a free plumber referral service) covers a town or ZIP in Delaware County, Pennsylvania.
```

### `request_contact`

- The name "request_contact" says "request": a word for a change.
- Tag outbound: The input takes a destination (input.phone): what the tool writes goes there.

Description, as the server wrote it:

```untrusted-server-text
Get the person connected with a local Delaware County plumber today (when one is available): send their phone number and/or email, problem and town, and Delco Plumber Now reaches out. Ask the person first ("Want Delco Plumber Now to reach out and connect you with a plumber? Share your phone or email.") and call this ONLY after they explicitly agree to the consent_text. Never invent contact details. We email a confirmation and call back; we only text after they text us.
```

## Only reads (2)

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

### `get_contact_info`

- The name "get_contact_info" says "get": a word for reading.
- Tag private-data: The name "get_contact_info" says "get" and "contact": it reads contacts. The description's first sentence says "get" and "email": it reads mail.
- Tag untrusted-input: The description's first sentence says "get" and "email": it reads inbound email, which other people can write.

Description, as the server wrote it:

```untrusted-server-text
Get the person connected with a Delaware County plumber now: phone to call or text (fastest), email and website.
```

### `get_price_range`

- The name "get_price_range" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Instant typical price range for a plumbing problem in Delaware County, PA (not a quote; the plumber confirms the price), plus how to get connected with a plumber now.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__plumber__get_price_range",
      "mcp__plumber__get_contact_info"
    ],
    "ask": [
      "mcp__plumber__check_coverage",
      "mcp__plumber__request_contact"
    ],
    "deny": []
  }
}
```

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

- `mcp__plumber__get_contact_info`: private-data, untrusted-input
- `mcp__plumber__request_contact`: outbound
