## Findings

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

```untrusted-server-text
The server marks "verify_company_claims" as not read-only (readOnlyHint: false), and its words say it reads.

annotations: {"readOnlyHint":false,"destructiveHint":false,"idempotentHint":false,"openWorldHint":true}; The description's first verb is "resolve": a word for reading.
```


## Changes things (1)

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

### `verify_company_claims`

- The description's first verb is "resolve": a word for reading.
- The server marks it as not read-only (readOnlyHint: false).
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Resolve a company, compare supported claims with current company evidence, preserve a proof record, and optionally monitor verified claims for change. This call consumes normal CompanyProof claim credits and writes to the account evidence ledger.
```

## Only reads (2)

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

### `get_company_profile`

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

Description, as the server wrote it:

```untrusted-server-text
Retrieve a CompanyProof company profile and enrichment payload by the opaque company ID returned from search_companies. This read-only operation requires an active CompanyProof evaluation or paid plan and live account access, and consumes one shared claim credit.
```

### `search_companies`

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

Description, as the server wrote it:

```untrusted-server-text
Find ranked CompanyProof company matches by name, registration number, VAT/tax identifier or ticker, optionally narrowed by subdivision and city/state. This read-only operation requires an active CompanyProof evaluation or paid plan and live account access, and consumes one shared claim credit.
```
