## Findings

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

```untrusted-server-text
The server marks "request_quote" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The name "request_quote" says "request": a word for a change.
```

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

```untrusted-server-text
The server marks "request_sds" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The name "request_sds" says "request": a word for a change.
```


## Changes things (5)

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

### `packaging_calculator`

- 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
How many drums, IBCs, bags or ISO tanks a quantity needs, from KORKİMYA product packaging data (same logic as the korkimya.com/araclar order calculators). calculator: 'dmea' (DMEA (Dimetiletanolamin)), 'dea99' (Dietanolamin Saf (DEA)), 'c9' (C9 Hidrokarbon Reçine), 'metilen' (Diklorometan (Metilen Klorür)), 'tofa' (TOFA (Tall Oil Yağ Asidi)). Counts are rounded up to whole packages; bulk options return no count. Commercial terms are quotation-only.
```

### `polymer_grade_selector`

- 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
Filter KORKİMYA polyethylene (PE) and polypropylene (PP) grades by polymer type, processing method (extrusion, injection moulding, blow moulding) and melt flow index range (g/10 min). Returns matching grades with melt flow index, density, processing methods and product page URL; grades whose specification does not state a filtered property are returned as 'unstated'.
```

### `request_quote`

- The name "request_quote" says "request": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Returns the matched product and the steps for requesting a quotation for it from the KORKİMYA Sales Department (contact page and email). Read-only: it submits nothing and collects no personal data.
```

### `request_sds`

- The name "request_sds" says "request": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Returns the matched product and the steps for requesting its safety data sheet (SDS) from the KORKİMYA Sales Department; SDS documents are shared on request. Read-only: it submits nothing and collects no personal data.
```

### `tofa_grade_selector`

- 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 KORKİMYA tall oil fatty acid (TOFA) or distilled tall oil (DTO) grades fit an application, optionally limited by maximum rosin acid (%) and minimum acid value (mg KOH/g). Each grade is marked guaranteed, typical, undefined or excluded against the constraints, with the evidence line from the product page and key specification values. application: alkid-recine, baski-murekkebi, dimer-asit, flotasyon, endustriyel-sabun, bitum-asfalt, metal-kesme-sivisi, yapistirici, kaucuk, yakit-katkisi, emulgator, yaglayici-gres, kaplama-vernik, esterlesme, endustriyel-recine, briket-pelet.
```

## Only reads (7)

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

### `cas_lookup`

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

Description, as the server wrote it:

```untrusted-server-text
Look up a chemical by CAS number (e.g. '111-42-2') or substance name (e.g. 'diethanolamine', 'TOFA'). Returns CAS checksum validity, PubChem identifiers (name, formula, molecular weight, IUPAC name, InChIKey, SMILES, CID), a GHS hazard summary when PubChem has one, and matching KORKİMYA catalogue products with product page URLs. This is not an official SDS: the safety data sheet is shared on request by the KORKİMYA Sales Department. Commercial terms are quotation-only.
```

### `compare_ethoxylates`

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

Description, as the server wrote it:

```

### `find_by_application`

- The name "find_by_application" says "find": a word for reading.

Description, as the server wrote it:

```untrusted-server-text

```
