## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data or untrusted-input 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. | 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 (2)

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

### `pick_secret_santa_gift`

- 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
Filters Santa's vetted 212 hand-checked gift ideas - the Secret Santa subset of the shared 255-idea bank it shares with its sister site The Present Picker, sorted here for Secret Santa by the budget band your group agreed for its draw - with strict parameters, and returns up to three picks. Parameters: budget_band (required: under_25, 25_to_50, 50_to_100, over_100); recipient_type (anyone, kid - only ideas from the bank's Kid shelf, or adult - everything except the Kid shelf); one interest hint (books, cooking, cozy, fitness, games, gardening, music, outdoors, science, tech, travel, or surprise) which ranks matches first; and avoid, a list of words - any idea whose name, blurb, or why mentions an avoid word is excluded, and the answer says how many ideas the filters set aside. Each pick names the kind of gift, why it fits, and what to look for and avoid. No brands, no stores, no exact prices: budget bands are guides, not exact prices. This tool never asks who the gift is for by name and knows nothing about any draw.
```

### `plan_secret_santa_setup`

- 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
Configures a Secret Santa group of 3 to 30 right here in chat and hands the organizer one pre-filled link to pickmysecretsanta.com, where the zero-knowledge draw runs in their browser - no server sees the matches, and each match will live inside one private link - hidden from plain sight, not locked. Give it the group's names and, optionally, a group name, a budget band, and keep_apart pairs (two-name lists, like [["Ana", "Ben"]], for people who must not draw each other): it validates the setup (3 to 30 people, no shared names - the site's draw cannot tell two same-named people apart) and checks that a valid draw exists under the keep-apart pairs before it returns the link with the group, names, budget, and pairs already in the form, plus the site's honest warnings; if the pairs leave no fair draw, it names the conflict plainly and returns no link. The link carries setup only - nobody has been assigned anyone. Names are used once to build the link and are never stored. With only a headcount (group_size) and no names, it instead returns the setup checklist the site prescribes: what to agree out loud first (buy-by date, what counts as a gift, the late-joiner rule, the reveal), the budget step, and how the browser draw works.
```

## Only reads (1)

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

### `explain_secret_santa_rules`

- The name "explain_secret_santa_rules" says "explain": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
The rules and fairness answers pickmysecretsanta.com itself publishes, worded the site's way. Topics: basics (the classic rules), fairness_and_secrecy (how the sealed draw works and its honest limits), organizer_view (the organizer sees names and links, never matches), keep_apart_pairs, late_joiner (the two honest ways to add someone after the draw), budget (the four bands), white_elephant (how it differs).
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `pick-my-secret-santa`:

```json
{
  "permissions": {
    "allow": [
      "mcp__pick-my-secret-santa__explain_secret_santa_rules"
    ],
    "ask": [
      "mcp__pick-my-secret-santa__pick_secret_santa_gift",
      "mcp__pick-my-secret-santa__plan_secret_santa_setup"
    ],
    "deny": []
  }
}
```
