## 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.

### `eini_create_meal_plan`

- The name "eini_create_meal_plan" says "create": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Make a NEW weekly meal plan (lunch and dinner, 7 days) in the user's EINI account, built around this week's Swiss supermarket deals, with its shopping list. Uses the user's saved EINI settings (people, diets, stores); you may change people, diets or language. Call it only when the user asks for a new plan: the new plan becomes their current plan in the app (earlier plans are not deleted). The account may need an EINI subscription for it (the answer says so). Needs the user's EINI login.
```

### `eini_my_meal_plan`

- 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
The user's current weekly meal plan from their EINI account (lunch and dinner per day, built around this week's Swiss supermarket deals). Without 'day': the week overview. With 'day': that day's recipes with ingredients, quantities and steps. Needs the user's EINI login. If there is no plan yet, the answer says so.
```

## Only reads (3)

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

### `eini_compare_health_insurance`

- The name "eini_compare_health_insurance" says "compare": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Official monthly premiums of Swiss basic health insurance (KVG / LAMal) for next year, cheapest insurer first, for a municipality or postcode, an age and a franchise. Optional: model (standard, family doctor 'hausarzt', HMO, Telmed) and accident cover (employees working 8+ hours a week are usually covered by their employer and can leave it out). Data: BAG, all insurers.
```

### `eini_my_shopping_list`

- The name "eini_my_shopping_list" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
The shopping list of the user's current EINI meal plan: each item with quantity, the store and product EINI picked (cheapest, using this week's deals), pack price in CHF and whether it is on promotion. By default only items not ticked off yet. Needs the user's EINI login.
```

### `eini_search_deals`

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

Description, as the server wrote it:

```untrusted-server-text
Find this week's promotions (Aktionen) at Swiss supermarkets: Coop, Migros, Lidl, Aldi, Denner, Aligro, Volg and Otto's. Search by product (any language; German/French/Italian names match best), filter by store and category. Returns at most 20 deals, biggest discount first, with price, regular price, discount and last day (null = while stocks last). A multi-buy offer (Coop's 'ab 2 Stück') adds a condition; its price is for one piece. Switzerland only, prices in CHF.
```

## Claude Code permissions

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 2 tools that change things (2 write). Whether a call also works without credentials was not tested: tools are never called.

https://api.eini.app/mcp: tools/list returned 5 tools to an anonymous client, including eini_my_meal_plan (write), eini_create_meal_plan (write)
