## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data 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. | `mcp__arugula__explain_match` `mcp__arugula__find_offers` `mcp__arugula__get_offers` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

- **warn** Annotations that disagree with the tool in `find_offers` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "find_offers" as not read-only (readOnlyHint: false), and its words say it reads.

annotations: {"readOnlyHint":false,"destructiveHint":false,"idempotentHint":false,"openWorldHint":true}; The name "find_offers" says "find": a word for reading.
```


## Changes things (1)

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

### `find_offers`

- The name "find_offers" says "find": a word for reading.
- The server marks it as not read-only (readOnlyHint: false).
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. The description's first sentence says "url": it reads web pages, which anyone can write.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Turns the user's request, with any context they stated (location, dates, budget, party size, preferences), into an intent and returns the offers that fit, best first, each with a tracked link to show the user (tracked_url). Matching runs in the background; when no offers are back yet, call get_offers with the intent_id in a few seconds. It never buys anything. By using Arugula you agree to arugulanet.com/terms. Privacy: arugulanet.com/privacy.
```

## Only reads (2)

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

### `explain_match`

- The name "explain_match" says "explain": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
One match with its explanation: why the offer fits the request, its fit and verification, and the draft terms (getMatch). brief: true leaves the explanation out. By using Arugula you agree to arugulanet.com/terms. Privacy: arugulanet.com/privacy.
```

### `get_offers`

- The name "get_offers" says "get": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. The description's first sentence says "url": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
The offers ranked for an intent from find_offers, best first, only those that fit, each with its tracked link (tracked_url) and how_to_buy. offer_id is the offer's public ID: lst_ for a merchant listing (open tracked_url to book with the merchant, no sign-in), off_ for a seller's offer on Arugula. By using Arugula you agree to arugulanet.com/terms. Privacy: arugulanet.com/privacy.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__arugula__get_offers",
      "mcp__arugula__explain_match"
    ],
    "ask": [
      "mcp__arugula__find_offers"
    ],
    "deny": []
  }
}
```

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

- `mcp__arugula__find_offers`: untrusted-input
- `mcp__arugula__get_offers`: untrusted-input
- `mcp__arugula__explain_match`: untrusted-input
