## 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__nutrition__lookup_food` |
| 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 (3)

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

### `check_claim`

- 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
For a RAW or minimally-processed whole food, or an unfortified single-ingredient flour, report which nutrition claims ("source of iron", "high in vitamin C", "high fibre") the published data supports under GB/EU rules (15%/30% of NRV per 100 g, Reg. 1924/2006) and US rules (10-19%/20% of DV per RACC, 21 CFR 101.54), and flags where that answer depends on which national food-composition table was used, since the 30 tables reconciled here disagree on the same food by a median of 1.96x. Applies to claims wherever they appear, including websites and advertising (Reg. 1924/2006 Art. 1(2)), not only packaging. NOT valid for cooked or manufactured products — their composition depends on recipe and processing. Screening only: under Art. 5(1)(b)(i) the nutrient must be in THE FINAL PRODUCT, so a supported claim still needs an analysis of the producer's own produce. Results list the tables that do and do not support each claim; the tool does not select a qualifying table.
```

### `health_topic`

- 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
What to eat for a health goal — the nutrients involved, why each one, and which raw recipes carry them — the "what should I eat for X" question. Accepts a goal ("gut health", "bone-health") or a named condition ("PCOS", "ADHD", "anaemia"): condition names resolve even though topic titles are physiological. Topics often looked up alongside a diagnosis include a note on what the evidence does and does not support, with its own evidence rating; for ADHD and autism the note states that diet is not a treatment, per NICE. Omit the argument to list every topic.
```

### `nutrient_ranking`

- 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
Ranks whole plant foods by the amount of one nutrient per 100 g of edible portion, optionally within one food category. Each row of `results` gives the value per 100 g, the number of sources behind it and, where heathy.org holds a typical serving for the food, that serving and the amount in it; the order is per 100 g. Foods eaten a few grams at a time (dried herbs, spices, tea leaves, and dried seaweed, mushrooms and vegetables) are not ranked in `results`. They are reported beside it in `also_higher.small_amounts`: a count of those holding more per 100 g than the last row, and the first five. They are ranked in `results` when include_small_amounts is true, and when the category filter selects mostly such foods ("spice", "tea", "seaweed"). With min_sources above 1, foods measured by fewer sources are reported in `also_higher.fewer_sources` in the same way. A nutrient that reads 0 on every food returns an explanation in `all_zero` and no ranking.
```

## Only reads (5)

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

### `get_recipe`

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

Description, as the server wrote it:

```untrusted-server-text
Get one Heathy recipe in full: ingredients with their food slugs and gram weights, method, per-serving nutrition, allergens and carbon footprint. All recipes are original, strictly raw / no-cook and vegan. The nutrition is computed from the ingredient food rows rather than entered by hand, so each figure traces back to the national datasets lookup_food cites. Accepts a slug or the recipe name; use search_recipes to find one.
```

### `herb_monograph`

- The description's first verb is "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Get a sourced monograph for an Ayurvedic herb, with traditional use and modern research kept strictly separate and never blended: `traditional` records what the tradition claims, `modern` records what research shows with an evidence tier (1 = strongest). Each response includes attribution, disclaimer, source_url and a `safety` block with cautions, pregnancy guidance and drug interactions. Accepts English, Sanskrit, Hindi or botanical names ("turmeric", "haldi", "Curcuma longa").
```

### `lookup_food`

- The name "lookup_food" says "lookup": a word for reading.
- Tag private-data: The description's first sentence says "get" and "table": it reads databases.

Description, as the server wrote it:

```untrusted-server-text
Get the full per-100 g nutrient profile of a whole plant food, reconciled across up to 30 national food-composition tables (USDA, UK CoFID, IFCT India, Ciqual, BLS, Fineli, and more). Unlike a single-source table, every value reports how many sources contributed, which ones, and the per-source spread — so the number can be cited rather than asserted. Covers Indian foods from IFCT 2017 (ICMR–NIN, India). Accepts a slug ("bitter-gourd") or a plain or regional name ("karela", "chickoo").
```

### `search_foods`

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

Description, as the server wrote it:

```untrusted-server-text
Find the Heathy slug for a food or Ayurvedic herb by name, including regional and non-English aliases (Hindi, Sanskrit, botanical names). Resolves a plain-English or local name to the slug that lookup_food and herb_monograph accept. Returns ranked candidates rather than guessing a single answer.
```

### `search_recipes`

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

Description, as the server wrote it:

```untrusted-server-text
Find raw / no-cook vegan recipes on Heathy by free text, health goal, category, ingredient, time or allergen. Every recipe is original and its per-serving nutrition is computed from the same food rows lookup_food returns, so figures are checkable rather than asserted. Returns ranked summaries — call get_recipe with a slug for ingredients, method and full nutrition. health_topic covers what the evidence supports for a goal or a named condition.
```

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 3 tools that change things (3 write). Whether a call also works without credentials was not tested: tools are never called.

https://mcp.heathy.org/mcp: tools/list returned 8 tools to an anonymous client, including nutrient_ranking (write), health_topic (write), check_claim (write)
