## Findings

No check matched anything in these tool definitions.


## Changes things (3)

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

### `interactions_check`

- 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
Which vitamins and minerals interact with given medications (generic or brand names, e.g. "warfarin", "Synthroid") or conditions, per the NIH Office of Dietary Supplements fact sheets, with timing advice (e.g. take levothyroxine 4 hours apart from calcium). No product list needed; to check an actual stack, pass medications to stack_analyze instead. Not exhaustive.
```

### `nutrients_reference`

- 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
NIH reference values (RDA, EAR, AI, UL) for one vitamin or mineral at a given age and sex, with what the UL protects against. Offline and instant.
```

### `products_fda_reports`

- 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
FDA recalls and adverse event reports (CAERS) for one supplement, from openFDA. Give a product name, barcode, DSLD ID, or brand and name. Recalls are listed only when they carry the barcode or the brand and every product-name word; adverse event reports are counted with their most common reactions. Reports do not show that a product caused an event.
```

## Only reads (4)

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

### `products_get`

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

Description, as the server wrote it:

```untrusted-server-text
Full normalized supplement labels by DSLD ID (up to 10): every ingredient with label amount, converted amount, form and %DV.
```

### `products_lookup`

- The name "products_lookup" says "lookup": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Look up a supplement by the UPC/EAN barcode printed on the bottle. Returns the newest matching DSLD label, normalized, and any older versions.
```

### `products_search`

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

Description, as the server wrote it:

```untrusted-server-text
Search the NIH Dietary Supplement Label Database by product name, brand or ingredient. Returns up to 10 products (one per product; older label versions listed in other_versions) with DSLD IDs.
```

### `stack_analyze`

- The name "stack_analyze" says "analyze": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Check a list of dietary supplements for a person: per-nutrient daily totals against NIH upper limits (UL) and RDA/AI, which products overlap, what each UL protects against, and single-product changes that would bring an above-UL nutrient back under it. Products can be given as names ("Centrum Silver Women 50+"), barcodes, DSLD IDs, or custom ingredient lists; optional candidates are evaluated as additions. Pass the person's medications and conditions (smoker, kidney_disease, hemochromatosis, lab_test_soon, cancer_treatment) to check them against the interactions in the NIH fact sheets. Returns agent_summary (plain sentences to relay), resolutions, suggestions, interactions, nutrient_totals and data_gaps. Label data only; food is included only with diet "typical".
```
