## Findings

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

```untrusted-server-text
The server marks "cross_walk" 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 description's first verb is "find": a word for reading.
```


## Changes things (3)

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

### `classify_text`

- 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
FREE TRIAL without a key: 20 calls per day per IP address in total for tariff_semantic_search, classify_text and finma_search. Each answer states the trial calls left; check every result on the NOGA publications of the Federal Statistical Office before use. Classify a business activity description (French, German, Italian or English) into the closest NOGA 2025 subclasses (6 digits) with their class (the NACE 2.1 class), official hierarchy and a similarity score, using a pinned multilingual mpnet model. A NOGA code as text lists its subclasses. Each answer states the index provenance and the classification reference version; combine with cross_walk for NACE, ISIC or NOGA 2008.
```

### `company_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
Look up a Swiss company by its UID (CHE-xxx.xxx.xxx): commercial register data (LINDAS), FINMA register entries and LEI records (GLEIF), each fact with its source and, when known, the date it was read, plus exact cross-checks between sources and checks of the registered address against the official localities and streets directories (swisstopo, when published). No score. When available, the commercial register status (active, in liquidation or deleted, with the deletion date) is read from Zefix (OFRC). FOSC publications, SECO sanctions and officers are not covered.
```

### `cross_walk`

- The description's first verb is "find": a word for reading.
- The input takes a statement or command to run (input.code), which can change anything it can reach.
- 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
Find correspondences between NOGA 2008, NOGA 2025, NACE 2.0, NACE 2.1 and ISIC 4 activity codes (Swiss, EU and UN classifications). Returns the exact or approximate relation, its sources and the documented path. Never chains two non-exact relations; a non-exact correspondence needs expert validation.
```

## Only reads (4)

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

### `finma_search`

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

Description, as the server wrote it:

```untrusted-server-text
FREE TRIAL without a key: 20 calls per day per IP address in total for tariff_semantic_search, classify_text and finma_search. Each answer states the trial calls left; check every result on the official FINMA register before use. Search the FINMA register by entity name, tolerant of case, accents, legal forms (AG, SA, Sàrl, GmbH, Ltd), ae/oe/ue spellings and one or two typos per word. Results are ranked exact, word start, whole word, prefix, substring, all words in any order, then typo guesses, each labelled with match_type. Set include_warnings=true to also search the FINMA warnings list. Each answer states the FINMA data version.
```

### `kyc_check`

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

Description, as the server wrote it:

```untrusted-server-text
Search the FINMA register of supervised institutions and the FINMA warnings list by name (case- and accent-insensitive). Returns the closest top_k authorised entities and warning entries (exact name, then whole word, then substring; all words in any order as a fallback) with the total number of matches. Only an identical name is reported as a FINMA warning-list match; a merely similar name is listed separately, to verify, and is never called a match. Use it for basic counterparty screening; no result is not a compliance certificate.
```

### `tariff_lookup`

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

Description, as the server wrote it:

```untrusted-server-text
Look up the Swiss customs tariff (TARES). An 8-digit Swiss tariff number (dots allowed) returns the full line: designations in FR/DE/IT/EN, MFN duty, preferential regimes, restrictions and customs relief codes. A 2- to 7-digit HS prefix (for example the international HS6 code) lists the Swiss 8-digit lines under it. Every result carries an unofficial-copy notice that the agent must show to the end user.
```

### `tariff_semantic_search`

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

Description, as the server wrote it:

```untrusted-server-text
FREE TRIAL without a key: 20 calls per day per IP address in total for tariff_semantic_search, classify_text and finma_search. Each answer states the trial calls left; check every result on the official tariff at xtares.admin.ch before use. Find Swiss customs tariff (TARES) lines from a description of the goods in French, German, Italian or English, or from a tariff number. Each line is indexed with its official hierarchy (heading, intermediate texts, 8-digit line) in the four languages; ranking puts shared official words first and uses meaning (pinned multilingual mpnet model) as a tie-breaker and for synonyms. Returns the 8-digit code, its official path, a relative score, the TARES data version and the index provenance. Always inlines a non-official disclaimer.
```
